Display panel and display device

[0001] Cross-reference to related applications

[0002] The present application claims priority to the Chinese patent application No. 202411389365.8, filed on September 30, 2024, and entitled "A display panel and display device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the technical field of light sensing, in particular to a display panel and display device. BACKGROUND

[0004] In related technologies, a light sensing transistor is integrated on a display panel supporting light sensing function, and an external ambient light intensity is detected through the light sensing transistor, such as a thin film transistor (TFT), so as to adjust display brightness. When the external ambient light irradiates the light sensing transistor, an electric current is generated when the light sensing transistor is turned on. The greater the light intensity, the greater the electric current. Therefore, the light intensity of the external ambient light can be determined according to the size of the electric current.

[0005] At present, the number of light sensing transistors integrated on the display panel is usually fixed during manufacturing. However, in a low-illumination environment, if the number of light sensing transistors is small, the electric current changes little due to weak ambient light, and it is difficult to achieve light intensity recognition accuracy. In a high-illumination environment, if the number of light sensing transistors is too large, the electric current is too large due to strong ambient light, which easily exceeds the light intensity recognition range, and it is difficult to obtain a recognition result.

[0071] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0072] FIG. 1 shows a structural schematic diagram of a display panel 10 according to an embodiment of the present application, which includes:

[0073] a plurality of integrated light sensing groups 101, each of which includes a plurality of light sensing transistors; wherein the light sensing transistors are configured to receive ambient light and generate a sensing signal at a first electrode of the light sensing transistors;

[0074] a plurality of first wires 102, each of which is connected to one of the integrated light sensing groups 101; wherein the first electrode of the light sensing transistors in the integrated light sensing group 101 is connected to the first wire 102 corresponding to the integrated light sensing group 101;

[0075] a plurality of signal output ends 103, each of which is connected to one of the first wires 102; wherein the first wire 102 is configured to transmit the sensing signal of the integrated light sensing group 101 to the signal output end 103.

[0076] In some embodiments, the display panel 10 supports a light sensing function, which refers to sensing and identifying the intensity of ambient light. The light sensing function generates a sensing signal through the light sensing transistors in the integrated light sensing group 101 receiving ambient light, so that the control circuit 20 connected to the display panel 10 detects the intensity and color temperature of the ambient light according to the sensing signal. A plurality of light sensing transistors are provided on the display panel 10. In this embodiment, the light sensing transistors are grouped into a plurality of integrated light sensing groups 101, each of which includes a plurality of light sensing transistors.

[0077] In some embodiments, the light sensing transistors in the display panel 10 can be the same size, such as the same type, size, and other parameters. For example, the light sensing transistors can be thin film transistors (TFT) with a W / L ratio of 20:4. The light sensing transistors can include a control electrode, a first electrode, and a second electrode, such as a gate electrode, a drain electrode, and a source electrode of the light sensing TFT. The light sensing transistors can receive ambient light and generate a sensing signal, such as a current signal, through photoelectric conversion.

[0078] Optionally, the number of light sensing transistors in different integrated light sensing groups 101 can be different.

[0079] In some embodiments, the number of light sensing transistors in different integrated light sensing groups 101 can be the same or different, which is not limited in the embodiments of the present application. Specifically, the light sensing transistors can be evenly grouped to obtain a plurality of integrated light sensing groups 101, and each integrated light sensing group 101 includes the same number of light sensing transistors. Alternatively, the light sensing transistors can be flexibly grouped, and the number of light sensing transistors in different integrated light sensing groups 101 can be different.

[0080] In this way, for the evenly grouped case, the number of light sensing transistors can be changed by adjusting the number of integrated light sensing groups 101 connected to the detection input end 201 of the control circuit 20. When the number of light sensing transistors in different integrated light sensing groups 101 is different, the detection input end 201 of the control circuit 20 can be directly connected to the integrated light sensing group 101 including the corresponding number of light sensing transistors according to the required number of light sensing transistors, and a plurality of integrated light sensing groups 101 can be connected to the detection input end 201 to flexibly combine different numbers of light sensing transistors to achieve more choices.

[0081] For example, the display panel 10 includes two integrated light sensing groups 101, and each of the two integrated light sensing groups 101 includes 75 light sensing transistors. When the detection input end 201 is connected to one integrated light sensing group 101, the number of light sensing transistors is 75, and when the detection input end 201 is connected to two integrated light sensing groups 101, the number of light sensing transistors is 150, that is, there are two selection schemes. Alternatively, the first integrated light sensing group 101 includes 75 light sensing transistors, and the other integrated light sensing group 101 includes 150 light sensing transistors, so that three selection schemes of 75, 150, and 225 can be obtained to provide more flexible choices.

[0082] In some embodiments, the light-sensing transistor can be a TFT or a Metal Oxide Semiconductor (MOS) field effect transistor, such as a Complementary Metal Oxide Semiconductor (CMOS) field effect transistor with a light-sensing function. The control electrode of the transistor can be a gate electrode, the first electrode can be a source electrode or a drain electrode, and the second electrode can be a drain electrode or a source electrode. For example, the light-sensing transistor can be an N-type TFT or a P-type TFT, and embodiments of the present application are not limited in this regard.

[0083] In some embodiments, the display panel 10 can be applied to a Liquid Crystal Display (LCD) device, an Organic Light-Emitting Diode (OLED) display device, or the like. For example, the display panel 10 can be an amorphous silicon (a-Si) LCD display panel. This is merely an example, and embodiments of the present application are not limited in this regard.

[0084] In some embodiments, each integrated light-sensing group 101 is further provided with a first wire 102 and a signal output terminal 103. That is, the first wires 102 corresponding to different integrated light-sensing groups 101 are different, and the signal output terminals 103 corresponding to different integrated light-sensing groups 101 are also different. Specifically, the plurality of integrated light-sensing groups 101 are connected to the plurality of first wires 102 in one-to-one correspondence. The first electrode of each light-sensing transistor in the integrated light-sensing group 101 is connected to the first wire 102 corresponding to the integrated light-sensing group 101. The plurality of signal output terminals 103 are connected to the plurality of first wires 102 in one-to-one correspondence, so that the first electrode of each light-sensing transistor is connected to the signal output terminal 103 corresponding to the integrated light-sensing group 101. In this way, the sensing signals generated by each light-sensing transistor can be transmitted to the signal output terminal 103 through the first wire 102.

[0085] For example, the integrated light-sensing group 101 is composed of a group of light-sensing TFTs. The drain electrodes of the light-sensing TFTs are connected to a signal line, which is referred to as a first wire 102. The first wire 102 is connected to the signal output terminal 103 corresponding to the integrated light-sensing group 101. The sensing signal corresponding to the integrated light-sensing group 101 includes the sensing signals generated by all the light-sensing transistors in the integrated light-sensing group 101.

[0086] In the embodiments of the present application, the display panel 10 includes a plurality of integrated light sensing groups 101, a plurality of first wires 102, and a plurality of signal output ends 103. The first wires 102 are connected to the integrated light sensing groups 101 one by one, and the signal output ends 103 are connected to the first wires 102 one by one. Therefore, each integrated light sensing group 101 has a corresponding first wire 102 and a corresponding signal output end 103. The integrated light sensing group 101 includes a plurality of light sensing transistors. When receiving ambient light, the light sensing transistors can generate a sensing signal at the first electrode of the light sensing transistor, that is, the light sensing transistor can detect ambient light and generate a corresponding sensing signal. The first electrode of the light sensing transistor is connected to the corresponding first wire 102 of the integrated light sensing group 101. Therefore, the sensing signal generated by each light sensing transistor of the integrated light sensing group 101 can be transmitted to the corresponding signal output end 103 of the integrated light sensing group 101 through the first wire 102. In this way, for different illuminance environments, the number of sensing signals output by the signal output end 103 can be flexibly selected, thereby selecting the number of integrated light sensing groups 101, and further matching the number of light sensing transistors with the current light environment. This can avoid the problem that the number of integrated light sensing transistors of the existing display panel 10 is fixed and may not adapt to the light environment, resulting in failure to meet the identification requirements.

[0087] Optionally, the display panel 10 includes a display area and a non-display area surrounding the display area.

[0088] The display area includes a pixel array; and the plurality of integrated light sensing groups 101 are arranged in the non-display area.

[0089] The plurality of integrated light sensing groups 101 are arranged in the non-display area along a first direction to form a light sensing array; and the first direction is parallel to a row direction of the pixel array.

[0090] In some embodiments, the plurality of integrated light sensing groups 101 are arranged in the non-display area surrounding the display area on the display panel 10. The non-display area of the display panel 10 includes a frame area outside the display area. Therefore, the plurality of integrated light sensing groups 101 are arranged in the frame area outside the display area of the display panel 10. Specifically, the display area of the display panel 10 is provided with a pixel array in which a plurality of pixels are arranged along a row direction and a column direction. The plurality of integrated light sensing groups 101 in the embodiments can be arranged in an array like the pixel array. The plurality of integrated light sensing groups 101 can be arranged in one or more rows along a first direction, which is not limited in the embodiments of the present application. In this way, a plurality of light sensing transistors in the plurality of integrated light sensing groups 101 form a light sensing array, and the display panel 10 detects ambient light through the light sensing array in the non-display area.

[0091] In some embodiments, the non-display area of the display panel 10 can include four bezel areas surrounding the display area, and the light sensing array can be arranged in at least one of the four bezel areas. Arranging the light sensing array in the non-display area of the display panel 10 and arranging the light sensing array in the pixel row direction of the pixel array in the display area can avoid occupying the area of the display area by the light sensing array, and improve the utilization rate of the display panel 10.

[0092] For example, the light sensing array formed by the plurality of integrated light sensing groups 101 can be arranged in the upper bezel area of the display panel 10, and the lower bezel area of the display panel 10 can be a binding area. Alternatively, the plurality of integrated light sensing groups 101 can be divided into two parts and arranged in the left and right bezel areas of the display panel 10. Here, only an example is given, and the embodiments of the present application do not limit this.

[0093] Optionally, the non-display area includes a binding area and a light sensing area.

[0094] The binding area is located at a first side of the display area, and the light sensing area is located at a second side of the display area; the first side and the second side are opposite sides of the display area.

[0095] The light sensing array is arranged in the light sensing area.

[0096] In some embodiments, the display panel 10 is bound to the control circuit 20 in the binding area. In the embodiments, the binding area is located at a first side of the display area of the display panel 10, and the light sensing array formed by the plurality of integrated light sensing groups 101 can be arranged in the light sensing area located at a second side of the display area. The first side and the second side are opposite sides of the display area. For example, the binding area can be located in the lower bezel area of the display panel 10, and the light sensing area can be located in the upper bezel area of the display panel 10, and the binding area and the light sensing area are arranged opposite to each other with respect to the display area.

[0097] In some embodiments, the plurality of integrated light sensing groups 101 can be arranged in a row in the light sensing area along a first direction, and the plurality of light sensing transistors in each integrated light sensing group 101 can be arranged in an array along the first direction. In the embodiments, the plurality of light sensing transistors in the integrated light sensing group 101 can be arranged in one or more rows, and the embodiments of the present application do not limit this. Alternatively, the plurality of integrated light sensing groups 101 can be arranged in a plurality of rows in the light sensing area along the first direction, and each row includes at least one integrated light sensing group 101, and the plurality of light sensing transistors in each integrated light sensing group 101 can be arranged in one or more rows along the first direction, and the embodiments of the present application do not limit this.

[0098] In some embodiments, the light sensing array is arranged in the light sensing area opposite to the binding area, so that the light sensing area and the binding area are arranged oppositely on the display panel 10 with respect to the display area, the width difference of the frame area on both sides of the display panel 10 can be reduced, the frame areas on both sides of the display panel 10 are as wide as possible, and the use effect of the display panel 10 is improved.

[0099] Optionally, in the light sensing area, the plurality of integrated light sensing groups 101 are arranged in a row along the first direction as the light sensing array.

[0100] In some embodiments, the plurality of integrated light sensing groups 101 are arranged in the light sensing area opposite to the binding area, and the plurality of integrated light sensing groups 101 are arranged side by side along the first direction, so that the plurality of integrated light sensing groups 101 are arranged in a row along the first direction as the light sensing array. In this way, the width of the frame area occupied by the light sensing array on the display panel 10 can be reduced, the frame area where the light sensing area is located is as narrow as possible, and the use effect of the display panel 10 is improved.

[0101] For example, the display panel 10 includes two integrated light sensing groups 101, the first integrated light sensing group 101 includes 75 light sensing TFTs, and the other integrated light sensing group 101 includes 150 light sensing TFTs. The two integrated light sensing groups 101 can be arranged in a row along the pixel row direction of the pixel array, i.e., the first direction, that is, the 75 light sensing TFTs and the 150 light sensing TFTs are arranged side by side along the first direction to obtain the light sensing array.

[0102] Optionally, in the plurality of integrated light sensing groups 101 arranged in a row, the plurality of light sensing transistors are arranged along the first direction.

[0103] In some embodiments, in order to further reduce the width of the frame area occupied by the light sensing array on the display panel 10, in the case of arranging the plurality of integrated light sensing groups 101 in a row in the light sensing area, the light sensing transistors in each integrated light sensing group 101 can also be arranged side by side, that is, the plurality of light sensing transistors in the integrated light sensing group 101 are arranged along the first direction.

[0104] Specifically, the light sensing transistor includes a control electrode, a first electrode, and a second electrode. The control electrodes of the plurality of light sensing transistors can be arranged in the opposite direction of the first direction, and the first electrode and the second electrode of the light sensing transistor are arranged in a direction perpendicular to the first direction, so that the light sensing transistors in the plurality of integrated light sensing groups 101 are arranged along the first direction, thereby arranging the light sensing transistors in the light sensing area in a row to form the light sensing array, and further reducing the width of the frame area occupied by the light sensing array in the direction perpendicular to the first direction.

[0105] For example, the 75 light-sensing TFTs and the 150 light-sensing TFTs of the two integrated light-sensing groups 101 are arranged in the light-sensing region along the first direction, and the 225 light-sensing TFTs of the two integrated light-sensing groups 101 form a row to form a light-sensing array.

[0106] Optionally, the first wires 102 include first portions of the wires located in the light-sensing region.

[0107] The first portions of the wires extend along the first direction.

[0108] In some embodiments, the signal output end 103 corresponding to the integrated light-sensing group 101 can not be arranged in the light-sensing region, and the first wires 102 are led out from the light-sensing region to connect the integrated light-sensing group 101 in the light-sensing region and the signal output end 103 outside the light-sensing region. The portion of the first wires 102 located in the light-sensing region is referred to as a first portion of the wire, that is, the light-sensing region is provided with a first portion of the wire corresponding to each first wire 102, that is, a plurality of first portions of the wires.

[0109] In some embodiments, the plurality of integrated light-sensing groups 101 are arranged in the light-sensing region along the first direction to form a light-sensing array. Correspondingly, the portion of the first wires 102 corresponding to the integrated light-sensing group 101 in the light-sensing region also extends along the first direction, and the first portions of the wires corresponding to the integrated light-sensing groups 101 in the light-sensing region extend along the first direction, so that the plurality of first portions of the wires in the light-sensing region are parallel to each other. In this way, the area of the plurality of first wires 102 occupying the frame area of the display panel 10 can be reduced.

[0110] Optionally, the display panel 10 further comprises:

[0111] a control wire 104, and the plurality of integrated light-sensing groups 101 are connected to the same control wire 104; wherein the control electrode of the light-sensing transistor is connected to the control wire 104;

[0112] a second wire 105, and the plurality of integrated light-sensing groups 101 are connected to the same second wire 105; wherein the second electrode of the light-sensing transistor is connected to the second wire 105.

[0113] In some embodiments, the control electrode of the light-sensing transistor is connected to the control wire 104 of the display panel 10, the second electrode is connected to the second wire 105 of the display panel 10, and the first electrode is connected to the first wire 102 corresponding to the integrated light-sensing group 101. In this way, the first electrodes of the plurality of light-sensing transistors in the integrated light-sensing group 101 are led out by one first wire 102, the control electrodes of all the light-sensing transistors in the plurality of integrated light-sensing groups 101 are led out by one control wire 104, and the second electrodes of all the light-sensing transistors are led out by one second wire 105. The plurality of light-sensing transistors in each integrated light-sensing group 101 are connected in parallel.

[0114] In some embodiments, the light sensing transistors receive ambient light, and the sensing signal generated by the light sensing transistors can be transmitted to the signal output end 103 corresponding to the integrated light sensing group 101 to which the light sensing transistor belongs through the first wire 102 when the light sensing transistor is turned on. Since the control electrodes of all the light sensing transistors in the plurality of integrated light sensing groups 101 are connected to the control wire 104, and the second electrodes of all the light sensing transistors are connected to the second wire 105, all the light sensing transistors can be turned on or turned off by controlling the control wire 104 and the second wire 105, so that the sensing signals generated by the light sensing transistors can be transmitted to the corresponding signal output end 103. In this way, the light sensing transistors can be turned on or turned off uniformly, the number of wires can be reduced, the control logic can be simplified, and the cost of the display panel 10 can be reduced.

[0115] For example, 75 light sensing TFTs are connected in parallel to form an integrated light sensing group 101, and 150 light sensing TFTs are connected in parallel to form another integrated light sensing group 101. The drain electrodes of the 75 light sensing TFTs are connected to one first wire 102, and the drain electrodes of the 150 light sensing TFTs are connected to another first wire 102. The first wire 102 can be a drain signal line, and the two first wires 102 are connected to the corresponding signal output end 103, respectively. The gate electrodes of the 75 light sensing TFTs and the 150 light sensing TFTs are connected to one control wire 104, and the source electrodes are connected to one second wire 105. The control wire 104 can be a gate signal line, and the second wire 105 can be a source signal line.

[0116] In some embodiments, the control wire 104 and the second wire 105 can also be arranged corresponding to each integrated light sensing group 101. In this way, the display panel 10 includes a plurality of control wires 104 and a plurality of second wires 105. The plurality of control wires 104 are connected to the integrated light sensing groups 101 one by one, and the plurality of second wires 105 are connected to the integrated light sensing groups 101 one by one. In this way, the control electrodes of the light sensing transistors in the integrated light sensing group 101 are connected to the control wire 104 corresponding to the integrated light sensing group 101, and the second electrodes are connected to the second wire 105 corresponding to the integrated light sensing group 101. This is only an example, and the embodiments of the present application are not limited thereto.

[0117] In this way, each integrated light sensing group 101 has a corresponding control wire 104, first wire 102, and second wire 105. The different integrated light sensing groups 101 are independent of each other, and each integrated light sensing group 101 can be controlled independently, so that the light sensing transistors in the integrated light sensing group 101 can be turned on or turned off uniformly. The number of integrated light sensing groups 101 can be selected more flexibly, and the number of light sensing transistors that are turned on can be selected flexibly.

[0118] For example, in a low-illumination environment, the number of turned-on light sensing transistors can be increased, so that the sensing signals generated by the light sensing transistors can reach the recognition accuracy. In a high-illumination environment, the number of turned-on light sensing transistors can be reduced to avoid exceeding the recognition range, so that the number of turned-on light sensing transistors can be more matched with the current illumination environment, and the versatility and flexibility of the display panel 10 can be improved.

[0119] In some embodiments, the plurality of first wires 102 can be arranged in the same layer or different layers, which is not limited in the embodiments of the present application. When arranged in the same layer, the plurality of first wires 102 can be arranged side by side, so that the area occupied by the first wires 102 on the display panel 10 can be reduced. When arranged in different layers, the plurality of first wires 102 can be arranged in two or more layers, which is not limited in the embodiments of the present application. In addition, the first wires 102 can be arranged in a single film layer, or the first wires 102 can be arranged in the same layer as other wires on the display panel 10, which is not limited in the embodiments of the present application.

[0120] Optionally, the plurality of first wires 102 are arranged in the same layer as the control wires 104,

[0121] and / or the plurality of first wires 102 are arranged in the same layer as the second wires 105.

[0122] In some embodiments, the control wires 104 can be arranged in a single layer, the second wires 105 can also be arranged in a single layer, or the control wires 104 and the second wires 105 can be arranged in the same layer, which is not limited in the embodiments of the present application. For example, the light sensing transistor is a light sensing TFT, the control wires 104 can be gate signal lines, the second wires 105 can be source signal lines, the control wires 104 can be arranged in a gate layer, the second wires 105 can be arranged in a source layer, or the control wires 104 and the second wires 105 can be arranged in the gate layer. This is only an example, which is not limited in the embodiments of the present application.

[0123] In some embodiments, the plurality of first wires 102 are arranged in the same layer and also arranged in the same layer as the control wires 104. Alternatively, the plurality of first wires 102 are arranged in the same layer and also arranged in the same layer as the second wires 105, or the plurality of first wires 102, the control wires 104, and the second wires 105 are all arranged in the same layer. In this way, the number of film layers of the display panel 10 can be reduced, and the cost of the display panel 10 can be reduced.

[0124] For example, the light sensing transistor is a light sensing TFT, the first wire 102 can be a drain signal line, and the plurality of first wires 102 can be arranged together with the control wire 104 in the gate layer. Alternatively, the plurality of first wires 102 can be arranged together with the second wire 105 in the source layer. Alternatively, the control wire 104 and the source wire are arranged in the gate layer, and the plurality of first wires 102 can also be arranged in the gate layer. Here, only an example is given, and the embodiments of the present application do not limit this.

[0125] Optionally, the at least one first wire 102 is arranged in the same layer as the control wire 104,

[0126] And / or, the at least one first wire 102 is arranged in the same layer as the second wire 105.

[0127] The control wire 104 and the second wire 105 are arranged in different layers.

[0128] In some embodiments, the control wire 104 and the second wire 105 are arranged in different layers, and the plurality of first wires 102 are also arranged in different layers. In order to reduce costs, a part of the first wires 102 can be arranged in the same layer as the control wire 104, and a part of the first wires 102 can be arranged in the same layer as the second wire 105. The plurality of first wires 102 can be arranged in two or more layers. When the plurality of first wires 102 are arranged in two layers, the two layers can be the film layer in which the control wire 104 is arranged and the film layer in which the second wire 105 is arranged. In this way, the number of film layers of the display panel 10 can be reduced, thereby reducing costs.

[0129] In related technologies, the sensing signal generated by the light sensing transistor is a current signal. One end of the sensing signal line of the light sensing transistor is connected to one end of the collection resistor, and the other end of the collection resistor is grounded. Therefore, the voltage signal corresponding to the current signal can be collected at the collection resistor. The greater the light intensity, the greater the current, and the greater the voltage at the collection resistor. Then, the ambient light intensity can be determined according to the voltage signal.

[0130] Optionally, the display panel 10 further comprises:

[0131] A plurality of collection resistors 106, the plurality of collection resistors 106 are connected one by one with the plurality of first wires 102; wherein the first end of the collection resistor 106 is connected with the first wire 102 to be connected to the signal output end 103; and the second end of the collection resistor 106 is grounded.

[0132] In some embodiments, each integrated light sensing group 101 corresponds to a collection resistor 106, and the collection resistor 106 is arranged on the display panel 10, that is, the display panel 10 further includes a plurality of collection resistors 106, and the collection resistors 106 correspond to the integrated light sensing groups 101 in a one-to-one manner. The first end of the collection resistor 106 is connected to the first trace 102 corresponding to the integrated light sensing group 101 and the signal output end 103, respectively. Then, the plurality of collection resistors 106 are connected to the plurality of first traces 102 in a one-to-one manner, and the plurality of collection resistors 106 are also connected to the plurality of signal output ends 103 in a one-to-one manner. In this way, the collection resistor 106 does not need to be arranged on the circuit board bound to the display panel 10, and the area occupation of the circuit board can be reduced.

[0133] In some embodiments, the sensing signal received by the light sensing transistor due to the ambient light can be a current signal. For example, the light sensing transistor receives the ambient light and generates photoelectric conversion to generate photo-generated carriers. When the light sensing transistor is turned on, a current signal is generated at the first electrode of the light sensing transistor due to the existence of the photo-generated carriers. The current signal is transmitted to the collection resistor 106 through the first trace 102, so that the first end of the collection resistor 106 generates a voltage signal, and the voltage signal is proportional to the current signal generated by the light sensing transistor. Then, the voltage signal is transmitted to the signal output end 103, so that the control circuit 20 can detect the ambient light according to the voltage signal.

[0134] Optionally, the display panel 10 includes a display area and a non-display area surrounding the display area.

[0135] The plurality of collection resistors 106 are arranged in the non-display area.

[0136] In some embodiments, the plurality of collection resistors 106 corresponding to the plurality of integrated light sensing groups 101 can be arranged in the frame area outside the display area, that is, the plurality of collection resistors 106 are arranged in the non-display area. Specifically, the plurality of collection resistors 106 can be arranged in one or more of the upper, lower, left and right frame areas of the display panel 10, and the present application does not limit this. In this way, the area occupation of the display area by the collection resistor 106 can be avoided, and the utilization rate of the non-display area can be improved.

[0137] In some embodiments, the light sensing area and the binding area on the display panel 10 are arranged relative to the display area, the plurality of collection resistors 106 can be arranged in the light sensing area together with the light sensing array, or the plurality of collection resistors 106 can be arranged in the binding area, and the present application does not limit this. When the plurality of collection resistors 106 are arranged in the binding area, the plurality of first traces 102 can pass through the frame areas on the other two sides of the display area, connect the light sensing transistors located in the light sensing area and the collection resistors 106 located in the binding area, and then the plurality of signal output ends 103 can be arranged in the binding area, and the plurality of first traces 102 can be connected to the plurality of signal output ends 103 in a one-to-one manner.

[0138] Optionally, the non-display area includes a binding area, and a first bezel area and a second bezel area adjacent to the binding area.

[0139] The acquisition resistor 106 is arranged in the first bezel area.

[0140] And / or, the acquisition resistor 106 is arranged in the second bezel area.

[0141] In some embodiments, the non-display area includes a binding area and a light sensing area arranged opposite to the binding area with respect to the display area. In order to avoid the bezel area where the light sensing area and the binding area are located being too wide, a plurality of acquisition resistors 106 can be arranged in the two side bezel areas adjacent to the binding area. Specifically, the non-display area includes four bezel areas around the display area, and the binding area and the sensing area are located in the opposite two side bezel areas, and the plurality of acquisition resistors 106 can be arranged in the remaining two side bezel areas.

[0142] In some embodiments, the two side bezel areas adjacent to the binding area are referred to as the first bezel area and the second bezel area. The plurality of acquisition resistors 106 can be all arranged in the first bezel area, or all arranged in the second bezel area, or part of the acquisition resistors 106 are arranged in the first bezel area and the remaining acquisition resistors 106 are arranged in the second bezel area, and the embodiments of the present application do not limit this. In this way, the acquisition resistors 106 can be arranged in the bezel area separated from the light sensing area and the binding area, improve the utilization rate of the non-display area, reduce the width difference of the four bezel areas of the display panel 10, and improve the use effect of the display panel 10.

[0143] Optionally, the plurality of integrated light sensing groups 101 are divided into two parts, the acquisition resistors 106 corresponding to the first part of the integrated light sensing groups 101 are arranged in the first bezel area, and the acquisition resistors 106 corresponding to the second part of the integrated light sensing groups 101 are arranged in the second bezel area.

[0144] The panel area occupied by the acquisition resistor 106 in the first bezel area is substantially equal to the panel area occupied by the acquisition resistor 106 in the second bezel area.

[0145] In some embodiments, the more the number of light sensing transistors in the integrated light sensing group 101, the greater the current transmitted through the first wire 102. In order to avoid the voltage signal generated at the first end of the collection resistor 106 exceeding the recognition range of the control circuit 20, the resistance value of the collection resistor 106 should be set according to the number of light sensing transistors in the integrated light sensing group 101. For example, the integrated light sensing group 101 composed of 75 light sensing TFTs can have a collection resistor 106 with a resistance value in the range of 80-120 megaohms (MΩ), and the integrated light sensing group 101 composed of 150 light sensing TFTs can have a collection resistor 106 with a resistance value in the range of 5-20 MΩ. This is only an example, and the embodiments of the present application do not limit this.

[0146] In some embodiments, the collection resistor 106 needs to occupy a certain area when it is arranged on the display panel 10, and the resistance value of the resistor is positively correlated with the size of the area occupied by the resistor. The resistance values of the collection resistors 106 corresponding to different integrated light sensing groups 101 can not be equal, and the panel area occupied by the collection resistors 106 corresponding to different integrated light sensing groups 101 can also not be equal. When the collection resistor 106 is arranged in the frame area of the display panel 10, the size of the panel area occupied by the collection resistor 106 will affect the size of the frame area, and thus affect the width of the frame of the display panel 10.

[0147] In some embodiments, the plurality of collection resistors 106 are arranged in two parts in the first frame area and the second frame area. In order to reduce the influence of the collection resistor 106 on the width of the frame of the display panel 10, and to reduce the width difference between the first frame area and the second frame area, the panel area occupied by the collection resistor 106 can be divided so that the panel area occupied by the collection resistor 106 in the first frame area and the second frame area is approximately equal. In this way, the width of the first frame area and the second frame area of the display panel 10 can be approximately equal, the symmetry of the first frame area and the second frame area of the display panel 10 can be improved, and the use effect of the display panel 10 can be improved.

[0148] Optionally, the first wire 102 includes a second part of the wire located in the first frame area; the second part of the wire extends along a second direction; the second direction is perpendicular to the first direction;

[0149] Alternatively, the first wire 102 includes a third part of the wire located in the second frame area; the third part of the wire extends along the second direction.

[0150] In some embodiments, the signal output end 103 corresponding to the integrated light sensing group 101 is arranged outside the light sensing area, the collection resistor 106 corresponding to the integrated light sensing group 101 is arranged in the first frame area or the second frame area, and the first trace 102 corresponding to the integrated light sensing group 101 passes through the frame area and then is connected with the signal output end 103. If the first trace 102 passes through the first frame area, the part of the first trace 102 in the first frame area is referred to as a second part of the trace. If the first trace 102 passes through the second frame area, the part of the first trace 102 in the second frame area is referred to as a third part of the trace.

[0151] In some embodiments, in order to reduce the area occupied by the first trace 102 in the first frame area and the second frame area, the second part of the trace in the first frame area can be arranged to extend along a second direction, so that a plurality of second parts of the trace are parallel to each other, and the third part of the trace in the second frame area can be arranged to extend along the second direction, so that a plurality of third parts of the trace are parallel to each other. Specifically, the first trace 102 can extend along the second direction in the first frame area or the second frame area, the second direction is perpendicular to the first direction, and the second direction is parallel to the pixel column direction of the pixel array. In this way, the utilization rate of the frame area can be improved, and the influence of the first trace 102 passing through the frame area on the frame width of the display panel 10 can be reduced.

[0152] Optionally, the display panel 10 comprises a ground trace;

[0153] The second ends of the plurality of collection resistors 106 are connected to the same ground trace.

[0154] In some embodiments, the ground trace of the display panel 10 can be arranged in the non-display area. For example, the ground trace can be the outermost GND trace in the non-display area, the ground trace surrounds the display area of the display panel 10 and surrounds the edge of the display panel 10 once. The ground trace and the collection resistor 106 can be arranged in different layers, and the film layer where the collection resistor 106 is arranged and the film layer where the ground trace is arranged can be connected through a via. Specifically, a via is punched from the second end of the collection resistor 106 to the film layer where the ground trace is arranged and connected with the ground trace.

[0155] In this way, the ground trace of the display panel 10 can be used to ground the second ends of the plurality of collection resistors 106, and the first ends of the collection resistors 106 can generate voltage signals according to the current signals, so that the control circuit 20 can detect the ambient light according to the voltage signals.

[0156] Optionally, the display area of the display panel 10 comprises a pixel array; the pixel array comprises a plurality of pixels.

[0157] The collection resistor 106 is arranged in the same layer as the first electrode of the pixel and has the same material.

[0158] In some embodiments, in order to reduce the cost of the display panel 10, the collection resistor 106 can be arranged by using the existing film layer of the display panel 10, for example, the collection resistor 106 can be arranged on the electrode layer of the pixel, and the collection resistor 106 can be made of the electrode material.

[0159] Specifically, the first electrode of the pixel in the pixel array is located on the first electrode layer, and the plurality of collection resistors 106 can be arranged on the first electrode layer and made of the electrode material of the first electrode, so that the collection resistors 106 are arranged in the same layer as the first electrode of the pixel and made of the same material. For example, the pixel includes an indium tin oxide (ITO) anode, and the collection resistor 106 can be arranged on the ITO layer and made of ITO material.

[0160] Optionally, the collection resistor 106 is composed of one or more linear resistors in series.

[0161] The linear resistor is a rectangular structure formed by the electrode material of the first electrode.

[0162] In some embodiments, since the control circuit 20 has limited ability to collect the voltage signal, after the number of light sensing transistors in the integrated light sensing group 101 is determined, the resistance value of the collection resistor 106 corresponding to the integrated light sensing group 101 can be calculated according to the size of the leakage current generated by the highest intensity light in the environment where the display panel 10 is located, so that the collection resistor 106 can be matched with the number and characteristics of the light sensing transistors of the corresponding integrated light sensing group 101.

[0163] In some embodiments, the collection resistor 106 is arranged in the same layer as the first electrode of the pixel, and the collection resistor 106 can be made of the electrode material of the first electrode. Given the sheet resistance of the electrode material, the final resistance value of the collection resistor 106 made of the electrode material is related to the shape and size of the collection resistor 106. Specifically, the linear resistor can be made of the electrode material, and the linear resistor can be a rectangular structure, and the length and width of the linear resistor can be determined according to the resistance value of the collection resistor 106.

[0164] For example, the sheet resistance of the ITO of the pixel is 70 (ohm per square micrometer), and the resistance value of the collection resistor 106 corresponding to the integrated light sensing group 101 composed of 75 light sensing TFTs is 10MΩ, and the shape of the linear resistor is 1um in width and 143mm in length.

[0165] In some embodiments, the collection resistor 106 can be a linear resistor, one end of the linear resistor is connected with the first wire 102 and the signal output end 103 respectively, and the other end is grounded. Alternatively, the collection resistor 106 can be composed of a plurality of linear resistors in series, and the embodiments of the present application do not limit this.

[0166] Specifically, the plurality of collection resistors 106 are arranged in the four frame regions surrounding the display area on the display panel 10. In order to reduce the area occupation of the collection resistor 106 on the frame region and reduce the influence of the collection resistor 106 arranged in the frame region on the frame width of the display panel 10, the collection resistor 106 can be composed of a plurality of linear resistors in series. Specifically, each linear resistor can be arranged flexibly in the frame region of the display panel 10, and the different linear resistors are connected in series with each other, and the first ends of the plurality of linear resistors connected in series are connected to the first wire 102 and the signal output end 103 respectively, and the tail ends are grounded.

[0167] For example, in a mobile module (Mobile), for an a-Si LCD display panel 10, the long side size of the panel is about 143 mm. Taking the resistance value of the collection resistor 106 corresponding to the integrated light sensing group 101 composed of 150 light sensing TFTs as 100MΩ, the collection resistor 106 can be composed of 5 linear resistors in series, and the shape of each linear resistor is 0.5um in width and 143mm in length. Among them, the 5 linear resistors are arranged in the frame region where the long side of the display panel 10 is located, and the 5 linear resistors connected in series can be arranged side by side, and the long side of each rectangular linear resistor can be substantially parallel to the long side of the display panel 10.

[0168] Optionally, the plurality of integrated light sensing groups 101 are divided into a plurality of detection arrays; each detection array includes at least two integrated light sensing groups 101.

[0169] The display panel 10 further includes a plurality of light filtering structures; the light filtering structures are arranged on the side of the detection array away from the substrate of the display panel 10.

[0170] Among them, the plurality of light filtering structures transmit light of different colors.

[0171] In some embodiments, the color temperature of the ambient light can be detected by the light sensing transistor and the light filtering structure. The ambient light transmits through the light filtering structure and irradiates on the light sensing transistor, and the light sensing transistor can generate a corresponding sensing signal. The control circuit 20 can detect the ambient brightness and light components according to the sensing signal, and can also compensate the color temperature of the display panel 10 according to the detection result. By integrating the detection array on the display panel 10 to detect the ambient color temperature, a special device such as an ambient light sensor is not needed, and the cost can be reduced.

[0172] In some embodiments, a plurality of detection conditions can be set, each detection condition corresponds to a detection array, and the plurality of integrated light sensing groups 101 are divided into a plurality of detection arrays. Among them, each detection array includes at least two integrated light sensing groups 101, so that the number of light sensing transistors can be flexibly selected under each detection condition, and the problem of unsuitable illumination environment can be avoided.

[0173] Optionally, the number of light sensing transistors in different integrated light sensing groups 101 in the detection array is different.

[0174] In some embodiments, the number of light sensing transistors included in different integrated light sensing groups 101 in the detection array can be the same or different, and the embodiments of the present application do not limit this. Specifically, when the number of light sensing transistors in different integrated light sensing groups 101 in the detection array is the same, the number of light sensing transistors can be changed by selecting the number of integrated light sensing groups 101 that are in communication with the detection input end 201 of the control circuit 20. When the number of light sensing transistors in different integrated light sensing groups 101 in the detection array is different, the number of light sensing transistors directly connected to the detection input end 201 and any integrated light sensing group 101 participating in light sensing is different, and in addition, more flexible selection can be achieved by connecting the detection input end 201 and multiple integrated light sensing groups 101.

[0175] In some embodiments, the corresponding light filtering structure can be arranged on the side of the detection array away from the substrate substrate according to the detection condition, and multiple different light filtering structures can be provided under multiple detection conditions, that is, the colors of the light transmitted by the multiple light filtering structures are different. The ambient light can pass through different light filtering structures and emit light of different colors, which can then be incident on the light sensing transistors in the detection array. In this way, the corresponding sensing signals of the detection array can reflect the light components of the ambient light under the detection condition, so that the control circuit 20 can perform ambient color temperature detection according to the corresponding sensing signals of the multiple detection arrays to obtain color temperature detection results under different detection conditions.

[0176] Optionally, the colors of the light transmitted by the multiple light filtering structures include red, green, and blue.

[0177] In some embodiments, the light filtering structure can be a color filter (CF), and specifically, can include red (R), green (G), and blue (B) color filters, which can be attached to the side of the detection array away from the substrate substrate. In this way, the colors of the light transmitted by different color filters are different, and the RGB components in the ambient light can be detected by different detection arrays after the ambient light passes through multiple color filters.

[0178] In some embodiments, the colors of the light transmitted by the multiple light filtering structures can also include white / colorless, for example, a white / colorless (W) color filter can be provided, so that RGBW color filters are attached to different detection arrays for ambient color temperature detection.

[0179] In some embodiments, the integrated light sensing group 101 in each detection array is connected to the signal output end 103 through the corresponding first wire 102, and each detection array includes at least two signal output ends 103. In different detection conditions, the corresponding signal output end 103 of the detection array can be set to the corresponding detection color, so that the control circuit 20 can determine the size of the light component of the corresponding color according to the sensing signals of different detection arrays.

[0180] Optionally, the display panel 10 further includes a black matrix.

[0181] The black matrix is arranged on the side of the corresponding detection array away from the substrate.

[0182] In some embodiments, a light-free environment corresponding detection condition can also be set, and the light-free environment can be used as a reference for light intensity detection and color temperature detection, and the detection results can be compared with the results under the light-free condition. For example, the detection results of light intensity / color temperature can be subtracted from the results under the light-free condition, so that the final light intensity and light component results are more accurate.

[0183] Specifically, the plurality of detection arrays divided by the plurality of integrated light sensing groups 101 can include a detection array provided with a black matrix (BM), and the black matrix can be arranged on the side of the detection array away from the substrate. After the ambient light irradiates the black matrix, the light cannot pass through, and thus the detection array under the black matrix corresponds to a light-free condition.

[0184] In some embodiments, the integrated light sensing groups 101 in the plurality of detection arrays can be connected to the same control wire 104 and connected to the same second wire 105, and the opening or closing of the light sensing transistor can be controlled by the control circuit 20. Alternatively, the plurality of detection arrays can be divided according to different detection conditions, and controlled by a plurality of control wires 104, so that the control circuit 20 can flexibly adjust the detection conditions.

[0185] For example, the detection arrays for detecting RGB light components can be connected to the same control wire 104, while the detection arrays for detecting white / colorless (W) and black matrix (BM) can be connected to another control wire 104. The second wire 105 is not distinguished, and RGBW and BM are connected to the same second wire 105. This is only an example, and the embodiments of the present application are not limited thereto.

[0186] The embodiments of the present application provide a display device, which includes a control circuit 20 and a display panel 10 as described in the foregoing embodiments.

[0187] The signal output end 103 corresponding to at least one integrated light sensing group 101 is in communication with the detection input end 201 of the control circuit 20.

[0188] In some embodiments, the non-display area of the display panel 10 includes a binding area in which the display panel 10 and the control circuit 20 are bound. The display panel 10 and the control circuit 20 can respectively include binding pins, the detection input end 201 of the control circuit 20 can be one of the binding pins of the control circuit 20, and the signal output end 103 corresponding to the integrated light sensing group 101 can be one of the binding pins of the display panel 10. The display panel 10 includes a plurality of binding pins, and the plurality of binding pins at least include the signal output ends 103 corresponding to the integrated light sensing groups 101 respectively.

[0189] In some embodiments, when the signal output end 103 and the detection input end 201 are in communication, the sensing signal generated by the integrated light sensing group 101 corresponding to the signal output end 103 can be transmitted to the control circuit 20 through the signal output end 103 and the detection input end 201, so that the control circuit 20 detects the ambient environment light according to the sensing signal. In this way, the number of integrated light sensing groups 101 can be selected by selecting the number of signal output ends 103 in communication with the detection input end 201 of the control circuit 20, and then the number of light sensing transistors can be flexibly selected in different illumination environments, so that the number of light sensing transistors matches the current light environment.

[0190] In some embodiments, the control circuit 20 further includes a control end and a detection output end, the control end is connected with the control wire 104 of the display panel 10, and the detection output end is connected with the second wire 105 of the display panel 10. The control circuit 20 sends a control signal to the control wire 104 through the control end, and outputs a detection signal to the second wire 105 through the detection output end, so as to control the light sensing transistors in the integrated light sensing group 101 to be turned on through the control signal and the detection signal, and output the sensing signal from the first wire 102 respectively. The control circuit 20 receives the sensing signal through the detection input end 201, and detects the light intensity or color temperature of the ambient light according to the sensing signal.

[0191] For example, the control circuit 20 is a display touch integrated control chip (TDDI IC) supporting light sensing function, the gate of all light sensing TFTs on the display panel 10 is connected to the control end of the TDDI IC through a signal line, i.e., the control wire 104, and the source of all light sensing TFTs is also connected to the detection output end of the TDDI IC through a signal line, i.e., the second wire 105. The control end and the detection output end of the TDDI IC can be one of the CGOUT Pin pins of the TDDI IC respectively. The light sensing TFT can be an N-type TFT, and the high level is effective. The TDDI IC can set the control signal as a 0V voltage signal, so as to set the gate voltage of the light sensing TFT as 0V, and set the detection signal as a square wave signal with a frequency of 10Hz, a high level of VGH, and a low level of GND, so as to control the light sensing TFT to be turned on or off through the control signal and the detection signal.

[0192] In some embodiments, the control circuit 20 includes a plurality of binding pins, which include a control end and a detection output end. If the photosensitive array is arranged in the photosensitive area opposite to the binding area, the control wire 104 is led out from the photosensitive area, passes through the first frame area or the second frame area adjacent to the binding area, and is finally connected to the control end of the control circuit 20 in the binding area. The second wire 105 is also led out from the photosensitive area, passes through the first frame area or the second frame area, and is finally connected to the detection output end.

[0193] In some embodiments, the control circuit 20 can include a plurality of detection input ends 201, wherein each detection array of the display panel 10 can correspond to one detection input end 201 of the control panel. For example, the detection arrays corresponding to RGBW and BM respectively correspond to one detection input end 201 of the control circuit 20. Specifically, for each detection array, the signal output end 103 corresponding to at least one integrated photosensitive group 101 in the detection array is connected to the detection input end 201 corresponding to the detection array. In this way, for each detection condition, the number of photosensitive transistors in different light environments can be adjusted by adjusting the number of integrated photosensitive groups 101 in the detection array that are connected to the detection input end 201 of the control circuit 20, which can improve the flexibility and adaptability of the display panel 10 under each detection condition.

As shown in FIG. 2, the display panel 10 includes detection arrays corresponding to five detection conditions of RGBW and BM, and the five detection arrays are arranged in the row direction in the upper frame area of the display panel 10.

The photosensitive transistor of the detection array is a photosensitive TFT, and the source of the photosensitive TFT in the five detection arrays is led out by one source signal line, i.e., the second wire 105. In the five detection arrays, the gate of the photosensitive TFT in the RGB detection array is led out by one gate signal line (Gate1), and the gate of the photosensitive TFT in the W detection array and the BM detection array is led out by one gate signal line (Gate2), and Gate1 and Gate2 are both control wires 104. The drain of the photosensitive TFT in each integrated photosensitive group 101 is led out by one drain signal line, i.e., the first wire 102.

[0195] As shown in FIG. 2, the display panel 10 is also bound with the control circuit 20, the control circuit 20 includes 5 detection inputs 201, and the 5 detection inputs 201 correspond to 5 detection arrays respectively. As shown in FIG. 2, the integrated light sensing group 101 in each detection array is connected with the corresponding detection input 201 through the corresponding first wire 102. In addition, the control wire 104 includes the left gate signal line Gate1 and the right gate signal line Gate2, and the second wire 105, i.e., the source signal line, can also be connected with the control circuit 20. The control circuit 20 can include two control ends connected with the gate signal line Gate1 and the gate signal line Gate2 respectively. The control circuit 20 can also include a detection output end connected with the source signal line.

[0196] FIG. 3 is an interface diagram of a control circuit 20 provided by an embodiment of the present application. As shown in FIG. 3, the control circuit 20 includes a plurality of binding pins, and the plurality of binding pins at least include the detection inputs 201, the control ends and the detection output end. Taking the display device shown in FIG. 2 as an example, as shown in FIG. 3, the control circuit 20 at least includes 5 detection inputs 201, i.e., D1-D5, 2 control ends, i.e., G1 and G2, and one detection output end, i.e., S.

[0197] Optionally, the display device further includes a first circuit board 30; the first circuit board 30 includes a first connection end 301 and a plurality of second connection ends 302.

[0198] The first connection end 301 is connected with the detection input 201 of the control circuit 20; and the plurality of second connection ends 302 are connected with the plurality of signal output ends 103 of the display panel 10 one by one.

[0199] Among the plurality of integrated light sensing groups 101, the second connection end 302 corresponding to at least one integrated light sensing group 101 is in communication with the first connection end 301, so that the first end of the collection resistor 106 corresponding to the integrated light sensing group 101 is in communication with the detection input 201.

[0200] In some embodiments, in the binding area of the display panel 10, the control circuit 20 is bound with the display panel 10, and the first circuit board 30 is also bound with the display panel 10. The display panel 10 and the first circuit board 30 can respectively include a plurality of binding pins. The first connection end 301 of the first circuit board 30 can be one of the plurality of binding pins, and the first connection end 301 of the first circuit board 30 and the detection input 201 of the control circuit 20 can be connected through the wire on the display panel 10. The number of the first connection end 301 can be consistent with the number of the detection input 201, and the first connection end 301 and the detection input 201 can be connected one by one. In this way, the first circuit board 30 and the control circuit 20 bound with the display panel 10 in the binding area are in communication with each other.

[0201] In some embodiments, the plurality of bonding pins of the first circuit board 30 includes a plurality of second connection terminals 302, which are connected one-to-one with a plurality of signal output terminals 103 in the display panel 10 bonding pins, so that the corresponding sensing signal of the integrated light sensing group 101 can be transmitted to the corresponding second connection terminal 302 through the signal output terminal 103. In actual application, the sensing signal corresponding to one or more integrated light sensing groups 101 needs to be transmitted to the control circuit 20 through the first connection terminal 301, and the second connection terminal 302 corresponding to the integrated light sensing group 101 can be connected with the first connection terminal 301. Further, the first end of the collection resistor 106 corresponding to each integrated light sensing group 101 is also connected with the detection input terminal 201 of the control circuit 20. The light sensing transistor receives the ambient light to generate a current signal, and when the light sensing transistor is turned on, the current signal is transmitted to the collection resistor 106, and a voltage signal can be generated at the first end of the collection resistor 106. The voltage signal is transmitted to the control circuit 20 through the signal output terminal 103, the second connection terminal 302, the first connection terminal 301 and the detection input terminal 201, that is, the control circuit 20 collects the voltage signal from the first end of the collection resistor 106.

[0202] For example, the first circuit board 30 can be a flexible printed circuit (FPC), which is bonded with the display panel 10, and the control circuit 20 can be a TDDI IC, which is also bonded with the display panel 10, and the detection input terminal 201 of the TDDI IC is connected with the first connection terminal 301 of the FPC through the wiring on the display panel 10. The drain of the light sensing TFT in the integrated light sensing group 101 is led out by a signal line, i.e., the first wiring 102, and connected to the signal output terminal 103, which is bonded with the second connection terminal 302 of the FPC corresponding to the integrated light sensing group 101. In this way, the first end of the collection resistor 106 corresponding to the integrated light sensing group 101 is connected with the second connection terminal 302 of the FPC, and the sensing signal of the integrated light sensing group 101, i.e., the voltage signal on the collection resistor 106, is led out to the device area of the FPC. In this way, the number of light sensing transistors in the current lighting environment can be changed by adjusting the position and number of the second connection terminals 302 on the FPC which are connected with the first connection terminal 301.

[0203] In the embodiment, when the ambient light irradiates the light-sensing TFT, and the source of the light-sensing TFT is in the high level stage, the drain of the light-sensing TFT will generate a current signal. Then, the current signal of each light-sensing transistor of the integrated light-sensing group 101 is transmitted to the collection resistor 106 through the first trace 102, and a voltage signal is generated at the first end of the collection resistor 106. When the corresponding second connection end 302 of the FPC of the integrated light-sensing group 101 is in communication with the first connection end 301, the TDDIIC can collect the voltage signal corresponding to the integrated light-sensing group 101 through the detection input end 201. The greater the light intensity of the external environment, the greater the current generated by the drain of the light-sensing TFT, and the greater the voltage collected by the TDDIIC from the collection circuit, that is, the external environment light intensity and the voltage signal collected by the TDDIIC are in a proportional relationship.

[0204] In this way, the TDDIIC can receive the voltage signal corresponding to the integrated light-sensing group 101 in communication with it through the detection input end 201, and then calculate the detection results such as the external environment light intensity and the light component size according to the voltage signal corresponding to each integrated light-sensing group 101 through the light-sensing curve pre-burned in the TDDIIC. In addition, the TDDIIC can also report the detection results, for example, to the mobile phone mainboard in the mobile phone module, so as to control the display brightness of the mobile phone.

[0205] In an alternative embodiment, the display panel 10 is bound to the circuit board, and the collection resistor 106 can be arranged on the circuit board. The signal line led out by the light-sensing transistor on the display panel 10 is connected to the circuit board through the binding pin (Pin), and then connected to one end of the collection resistor 106 through the trace on the circuit board. The other end of the collection resistor 106 is grounded. However, this requires adding the collection resistor 106 on the circuit board bound to the display panel 10, which will occupy the area of the circuit board and increase the cost.

[0206] Specifically, the display panel 10 is bound to the FPC, and the collection resistor 106 is arranged on the FPC. The signal line led out by the drain of the light-sensing TFT on the display panel 10 is pulled out to the FPC device area through the binding pin, and then connected to one end of the collection resistor 106 through the trace on the FPC. The other end of the collection resistor 106 is grounded. Then, the voltage signal at the front end of the collection resistor 106 on the FPC is pulled out, and is given to the TDDIIC through the binding pin of the FPC and the TDDIIC and the trace on the display panel 10. However, this requires adding the collection resistor 106 on the FPC, which will occupy the area of the FPC and increase the cost.

[0207] Fig. 4 is a structural schematic diagram of another display device provided by the embodiment of the present application. As shown in Fig. 4, two detection arrays are arranged in the frame area close to the upper edge of the display panel 10. One detection array is used for light sensing and can detect ambient light, and the other detection array is in a lightless condition and can be used as a reference for light intensity detection or color temperature detection. Each detection array includes an integrated light sensing group 101. The light sensing transistors in the integrated light sensing group 101 are light sensing TFTs. The drain of the light sensing TFT in each integrated light sensing group 101 is led out as a first wire 102. Each of the two detection arrays leads out one first wire 102. The two first wires 102 respectively pass through the frame areas on the left and right sides of the display panel 10 to the frame area at the lower edge of the display panel 10. The lower edge of the display panel 10 is provided with a binding area, and the display panel 10 is bound with an IC chip and an FPC.

[0208] As shown in Fig. 4, the FPC includes four binding pins Pin1-Pin4. The Pin2 pin and the Pin4 pin are respectively the first connection end 301 corresponding to each of the two detection arrays, and the Pin2 pin and the Pin4 pin are bound with the display panel 10 and connected with the two detection input ends 201 of the IC chip through the wires on the display panel 10. The Pin1 pin is the second connection end 302 corresponding to the detection array for light sensing, and the Pin3 pin is the second connection end 302 corresponding to the detection array in a lightless condition. The first wires 102 corresponding to the two detection arrays are respectively led out to the device area of the FPC through the Pin1 pin and the Pin3 pin. Referring to Fig. 4, a collection resistor (R) is arranged on the FPC, the Pin1 pin and the Pin3 pin are respectively connected with the first end of the collection resistor, and the second end of the collection resistor is grounded. The Pin1 pin is in communication with the Pin2 pin, and the Pin3 pin is in communication with the Pin4 pin. In this way, the IC chip can collect voltage signals and further detect ambient light.

[0209] It should be noted that the voltage signals corresponding to each integrated light sensing group 101 of the display panel 10 under several illuminations can be collected in advance, and then the light sensing curve of the display panel 10 is generated according to the actual ambient illumination and the voltage signals, and the light sensing curve is stored in the control circuit 20, so that the control circuit 20 detects the light intensity and light components according to the light sensing curve. Specifically, a standard light source can be used to collect the sensing signals of the display panel 10 under several illuminations, and the light sensing curve of the external ambient light and the sensing signals is generated according to the several illuminations and the sensing signals. The light sensing curve is pre-stored in the control circuit 20, so that the control circuit 20 detects the ambient light intensity and light components according to the light sensing curve.

[0210] For example, the light-sensing TFT generates a current signal at the drain, the TDDI IC collects a voltage signal from the first end of the collection resistor corresponding to the integrated light-sensing group 101, and burns a plurality of illumination data and the voltage signal into the TDDI IC. The TDDI IC generates a light-sensing curve of the external ambient light and the voltage signal according to a certain algorithm. In this way, when the TDDI IC collects a voltage signal from the detection input end 201, the detection result of the ambient light can be obtained according to the collected voltage signal and the pre-stored light-sensing curve. This is only an example, and the embodiments of the present application are not limited thereto.

[0211] FIG. 5 is a schematic diagram of a light-sensing curve provided by an embodiment of the present application. As shown in FIG. 5, the vertical coordinate represents the collected voltage, and the unit is volt (V), and the horizontal coordinate represents the illumination, and the unit is lux. As shown in FIG. 5, the curve formula is lux = V / k, where k is a fixed coefficient. Referring to FIG. 5, for example, after the light-sensing module is assembled into a mobile phone, when the light-sensing TFT receives external ambient light during use of the mobile phone, the TDDI IC collects a voltage signal through the light-sensing TFT drain voltage detection circuit, and then the intensity and light component of the external ambient light can be accurately calculated through the pre-burned light-sensing curve.

[0212] In some embodiments, taking an a-Si LCD light-sensing module as an example, the manufacturing process of the display device provided by the embodiments of the present application is described. As shown in the flowchart of FIG. 6, a plurality of light-sensing TFTs, i.e., a plurality of integrated light-sensing groups 101, can be manufactured on the array substrate, and a collection resistor 106 corresponding to each integrated light-sensing group 101 can be manufactured on the pixel ITO layer. The gate and source of the light-sensing TFT are led out by a signal line, and the gate of the light-sensing TFT in each integrated light-sensing group 101 is led out by a signal line. The manufacturing process can refer to the current LCD display panel 10. Then, a BM light-shielding layer can be manufactured on the color film substrate, wherein the RGB color film position needs to be hollowed out directly above the integrated light-sensing group 101, and then the RGB color film is manufactured directly above the integrated light-sensing group 101 on the BM. Next, the array substrate and the color film substrate are aligned to form a light-sensing LCD screen, large Q is cut into a single cell, and after ET lamp detection, the polarizing plate is cleaned and attached. Then, the IC chip and the FPC are bound, and the cover plate is attached and the backlight is assembled and welded, and finally the light-sensing module with ambient light detection function is completed. Then, the original illumination data is collected under a standard light source and burned into the IC chip, and the IC chip can generate a light-sensing curve according to a certain algorithm, so that the light-sensing module can detect the ambient light, such as identifying the intensity of the ambient light.

[0213] FIG. 7 is a structural schematic diagram of a display device in the related art. As shown in FIG. 7, a plurality of light-sensing TFTs are arranged in the upper frame area of the display panel, the plurality of light-sensing TFTs are connected in parallel with each other, and the gate, source and drain of the plurality of light-sensing TFTs are each led out by a signal line. As shown in FIG. 7, the gate trace, the source trace and the drain trace pass through the left frame area of the display panel to the single-layer area of the display panel. In the single-layer area of the display panel, the display panel is bonded with an IC chip and an FPC. A collection resistor is arranged on the FPC, one end of the collection resistor is connected to the bonding pin of the FPC and the display panel, and the other end of the collection resistor is connected to the ground end of the FPC. In addition, the outermost circle of the display panel further includes a GND trace, which is led out to the FPC and connected to the ground end of the FPC. The voltage signal at the D point at the front end of the collection resistor is pulled out to the IC chip, so that the IC chip can detect the ambient light intensity according to the collected D point voltage.

[0214] In the related art, in a low-illumination environment, if the number of light-sensing transistors is small, for example, 75 light-sensing TFTs, the sensitivity of the display panel is not high. When the ambient light is weak, the current generated by the light-sensing transistor is small, the voltage change at one end of the collection resistor is not large, and the change precision of the calculated ambient light cannot meet the recognition standard. For example, the recognition standard can be that the light intensity recognition precision needs to reach 0.5 lux recognition ability in low-intensity light. In a high-illumination environment, if the number of light-sensing transistors is too large, for example, 150 light-sensing TFTs, when the ambient light is strong, the current generated by the light-sensing transistor is large, the voltage generated at one end of the collection resistor is large, and is easy to exceed the voltage recognition range of the IC chip. For example, the maximum saturation voltage of the TDDI IC currently supporting light-sensing function is between 4-5V, which makes it difficult to obtain a recognition result and cannot meet the standard of recognizing high-intensity ambient light. For example, the standard can be to recognize ambient light with an intensity of 50000-100000 lux.

[0215] In addition, for the light-sensing TFT, the leakage fluctuation of the TFT itself is large, and the more the number of TFTs connected in parallel on the display panel, the larger the leakage fluctuation. In this way, the voltage signal collected by the TDDI IC is not only generated by the external environment, but also by the leakage fluctuation of the TFT itself, which causes the ambient light intensity calculated by the TDDI IC to deviate from the true ambient light intensity, i.e., the accuracy is not high and can be lower than the error standard. For example, the error standard is that the error is <15%.

The first part of the first wire 102 in the light sensing area extends along the first direction.
