Description

Technical Field

[0001] This application relates to the field of display technologies, and particularly to a display panel and a display device. Background Art

[0002] Touch display panels are widely used in various electronic devices, such as mobile phones, tablet computers, smart watches, and in-vehicle central control displays. As an important interface for human-computer interaction, the display quality of touch display panels is a key concern for users.

[0003] Currently, the display surface of touch display panels usually has a relatively high reflectivity. When external light irradiates the display surface of the touch display panel, a part of the light will be reflected. This reflection not only causes a decrease in the clarity of the displayed content, affecting the accurate reading of the display information by users; but also easily forms glare on the display surface of the touch display panel. Especially in strong light environments (such as direct sunlight outdoors or strong indoor lighting), the glare will seriously interfere with users' viewing of the displayed content and increase eye fatigue.

[0027] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. The described technical solutions are only used to explain and illustrate the idea of the present application, and should not be regarded as a limitation on the protection scope of the present application.

[0028] In the description of the present application, it should be understood that terms such as "first", "second" and similar words do not denote any order, quantity or importance, but are only used to distinguish different technical features. The term "plurality" and similar words mean two or more, unless otherwise clearly defined.

[0029] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0030] The use of "for" in the present application means open and inclusive language, which does not exclude devices that are suitable for or configured to perform additional tasks or steps.

[0031] In the present application, the term "exemplary" is used to mean "serving as an example, illustration, or explanation". Any embodiment described as "exemplary" in the present application is not necessarily construed as being more preferred or advantageous than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application.

[0032] The various embodiments of the present application are similar, and the features in different embodiments and / or different examples can be combined with each other.

[0033] Some embodiments of the present application provide a display panel, as Figures 1 to 3 shown, the display panel 100 includes a first touch layer 11 and a second touch layer 13 sequentially arranged along its light-emitting direction.

[0034] The first touch layer 11 includes a plurality of first touch structures 111; the second touch layer 13 includes a plurality of second touch structures 131, and each second touch structure 131 is electrically connected to a first touch structure 111. As an example, the display panel 100 further includes an insulating layer 12 located between the first touch layer 11 and the second touch layer 13, and the second touch structure 131 is electrically connected to the first touch structure 111 through a via 120 in the insulating layer 12.

[0035] Wherein, one of the first touch structure 111 and the second touch structure 131 is a touch electrode, and the other is a touch trace. For example, the first touch structure 111 is a touch electrode, and the second touch structure 131 is a touch trace. Or, the first touch structure 111 is a touch trace, and the second touch structure 131 is a touch electrode.

[0036] In some examples, multiple touch electrodes may be arranged in an array (e.g., in a matrix arrangement). By means of the array arrangement, a uniform touch sensing area can be formed on the surface of the display panel.

[0037] When a finger approaches or touches the display surface of the display panel 100, a capacitance is formed between the touch electrode located within the touch sensing area corresponding to the finger and the finger. Since the human body is a conductor, it will change the electric field distribution around the touch electrode, thereby causing a change in the capacitance value of the touch electrode. Through the signal input and output of the touch trace, the change in the capacitance value of the touch electrode can be monitored, thereby determining the touch position of the finger.

[0038] In some examples, each touch electrode may be rectangular, diamond-shaped or circular, and the embodiments of the present application do not limit this. As an example, each touch electrode is rectangular, and its side length can be set in the range of 3 mm to 4 mm. Optionally, the above side lengths can be 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 4.0 mm.

[0039] In some embodiments, as Figure 2 shown, the second touch structure 131 is used to reflect the first part of the ambient light L1 and transmit the second part of the ambient light L2. The first touch structure 111 is used to reflect the second part of the light L2 so that the second part of the light L2 interferes with the first part of the light L2. In Figure 2 the figure, the ambient light is represented by a thick black solid line with an arrow, the first part of the light L1 is represented by a thin black solid line with an arrow, and the second part of the light L2 is represented by a dotted line with an arrow.

[0040] With this setting, when the external light (i.e., the ambient light) passes through the display surface of the display panel 100, the first part of the light L1 is reflected by the second touch structure 131, and the second part of the light L2 is transmitted to the surface of the first touch structure 111, and then reflected by the first touch structure 111 and finally exits. The first part of the light L1 and the second part of the light L2 disappear due to interference, so that the light reflected by the display surface of the display panel 100 is reduced or disappears, thereby effectively reducing the reflectivity of the display panel 100 to the ambient light.

[0041] As an example, by making the first part of the light L1 and the second part of the light L2 have the same frequency, the same vibration direction, and a constant phase difference, the first part of the light L1 and the second part of the light L2 can be made to interfere.

[0042] In some examples, the refractive indices of the second touch structure 131 and the insulating layer 12 can be adjusted so that the first part of the light L1 and the second part of the light L2 can interfere.

[0043] In some embodiments, the proportions of the first partial light L1 and the second partial light L2 in the ambient light are the same. For example, the proportion of each is 50%.

[0044] In this case, the amount of ambient light reflected by the second touch structure 131 and the amount of ambient light reflected by the first touch structure 111 can be made the same, so that this part of the ambient light can be better made to disappear through the interference effect, thereby effectively reducing the reflectivity of the display panel 100 to the ambient light.

[0045] In some examples, the second touch structure 131 includes a reflective metal. By setting the planar coverage rate of the reflective metal on the second touch structure 131, the second touch structure 131 can have a semi-transmissive and semi-reflective function.

[0046] The second touch structure 131 may further include a transmissive portion, and the transmissive portion may be made of a transparent conductive material. As an example, the transmissive portion has a grid structure, so that the light transmittance of the transmissive portion can be improved. In this case, by adjusting the reflective metal and the transmissive portion, it is beneficial to control the proportions of the first partial light L1 and the second partial light L2 in the ambient light.

[0047] In other examples, the second touch structure 131 may include a semi-transmissive and semi-reflective metal material.

[0048] In some embodiments, as Figure 2 shown, the first touch structure 111 is a touch trace 110, and the second touch structure 131 is a touch electrode 130.

[0049] By arranging the touch trace 110 at a layer position relatively far from the display surface of the display panel 100, the interference of external factors on the signals in the trace can be effectively reduced. In addition, since the touch trace 110 needs to be connected to a touch chip or a control circuit, etc., arranging the touch trace 110 at a layer position relatively far from the display surface of the display panel 100 can also enable the touch trace 110 to be connected to the touch chip or the control circuit with a shorter path, thereby reducing the loss during the signal transmission process.

[0050] In some embodiments, as Figure 3 and Figure 4 shown, the first touch layer 11 further includes a reflective structure 112, and the reflective structure 112 is arranged at an interval from the touch trace 110. The reflective structure 112 is used to reflect a part of the light transmitted through the second touch layer 13.

[0051] Compared with the touch electrode 130, the touch trace 110 has a smaller area, so the amount of light it reflects is less. By providing the reflection structure 112, the reflection area of the first touch layer 11 for the light transmitted through the second touch layer 13 can be increased, thereby improving the reflection effect on this part of the light, increasing the amount of interfering light, and further reducing the reflectivity of the display panel 100 to ambient light.

[0052] It should be noted that during the wiring process of the touch traces 110, different touch traces 110 are spaced apart from each other, and any touch trace 110 does not come into contact with the reflection structure 112.

[0053] In some examples, the surface of the reflection structure 112 and the surface of the touch trace 110 can be in the same plane, which can make the reflection structure 112 and the touch trace 110 have the same reflection effect on ambient light, thereby effectively reducing the reflectivity of the display panel 100 to ambient light.

[0054] In some embodiments, the surface of the reflection structure 112 has a micro-nano structure, and the micro-nano structure includes periodically arranged nano-columns or nano-holes, which can enhance the light reflectivity of the reflection structure 112.

[0055] In some embodiments, please continue to refer to Figure 3 and Figure 4 , the reflection structure 112 has a plurality of wiring channels T, and each touch trace 110 is located in a wiring channel T.

[0056] By providing the wiring channels T on the reflection structure 112, the reflection structure 112 can have a relatively large area, thereby improving the reflection effect of the reflection structure 112 on the light transmitted through the second touch layer 13, increasing the amount of interfering light, and further reducing the reflectivity of the display panel 100 to ambient light.

[0057] In some embodiments, as Figure 3 and Figure 5 shown, the display panel 100 has a first area A1 and a second area A2. The second area A2 is located on one side of the first area A1. The touch electrode 130 is located in the first area A1. The display panel 100 further includes a touch chip 31 located in the second area A2. One end of each touch trace 110 is electrically connected to a touch electrode 130 through a via 120 in the insulating layer 12, and the other end of the touch trace 110 is electrically connected to the touch chip 31. Among them, the second area A2 can be used as a touch function area of the display panel for arranging the touch chip 31.

[0058] As Figure 5 shown, the plurality of wiring channels T include a first wiring channel T1 and a second wiring channel T2;

[0059] The multiple touch traces 110 include a first touch trace 1101 electrically connected to the touch electrodes on the side away from the touch chip 31 and a second touch trace 1102 electrically connected to the touch electrodes on the side close to the touch chip 31. Among them, the first touch trace 1101 is located in the first wiring channel T1, the second touch trace 1102 is located in the second wiring channel T2, and the length of the first wiring channel T1 is greater than the length of the second wiring channel T2.

[0060] For the second touch trace 1102, since it is electrically connected to the touch electrodes on the side close to the touch chip 31, its wiring length is shorter than that of the first touch trace 1101. By setting the second wiring channel T2 where the second touch trace 1102 is located to be shorter in length, the layout area of the reflection structure 112 can be increased, thereby improving the reflection effect of the reflection structure 112 on the light transmitted through the second touch layer 13, increasing the amount of interfering light, and further reducing the reflectivity of the display panel 100 to ambient light.

[0061] In some embodiments, such as Figure 4 and Figure 5 as shown, two adjacent wiring channels T are communicated with each other.

[0062] For example, the first wiring channel T1 and the second wiring channel T2 can be two adjacent wiring channels T. When the first wiring channel T1 and the second wiring channel T2 are not communicated, there are gaps between the first touch trace 1101 and the side walls of the wiring channel where it is located, and between the second touch trace 1102 and the side walls of the wiring channel where it is located, so as to ensure that neither the first touch trace 1101 nor the second touch trace 1102 contacts the reflection structure 112. In this way, there are four gaps between the two touch traces 110 and the side walls of their respective wiring channels.

[0063] By setting the first wiring channel T1 and the second wiring channel T2 to be communicated with each other, the first touch trace 1101 and the second touch trace 1102 can share the gap between them, so that there are only three gaps between the two touch traces 110 and the side walls of their respective wiring channels. This is beneficial to increasing the layout area of the reflection structure 112, thereby improving the reflection effect of the reflection structure 112 on the light transmitted through the second touch layer 13, increasing the amount of interfering light, and further reducing the reflectivity of the display panel 100 to ambient light.

[0064] In some embodiments, along the thickness direction perpendicular to the display panel 100, the total area of the reflection structure 112 and all the touch traces 110 is greater than the total area of all the touch electrodes 130.

[0065] By setting it in this way, the first touch layer 11 can have a relatively large reflection area, so that a good reflection effect can be formed on the ambient light transmitted to the first touch layer 11, thereby increasing the amount of interfering light and further reducing the reflectivity of the display panel 100 to the ambient light.

[0066] In some embodiments, such as Figure 3 and Figure 6 shown, the touch electrode 130 is provided with a first opening K1.

[0067] The display panel 100 further includes: a plurality of light-emitting devices 41, and a spacer layer 22 and a driving circuit layer 21 that are sequentially arranged on a side of the first touch layer 11 away from the insulating layer 12, and the driving circuit layer 21 is located on a side of the spacer layer 22 away from the first touch layer 11. Among them, the spacer layer 22 can be made of an insulating material.

[0068] Each light-emitting device 41 is at least partially located in the first opening K1 and is electrically connected to the driving circuit layer 21 through a contact hole in the spacer layer 22.

[0069] By setting it in this way, since the light-emitting device 41 is located in the first opening K1, it can effectively avoid the light emitted by the light-emitting device 41 being easily blocked by the first touch layer 11 and the second touch layer 13 when the light-emitting device 41 is arranged on a side of the first touch layer 11 close to the driving circuit layer 21. In this way, a good display effect can be obtained. Therefore, the display panel 100 in this embodiment has both display and touch functions, the overall thickness of the display panel 100 is relatively thin, and the manufacturing process is also relatively simple.

[0070] As an example, the light-emitting device 41 can be a miniature light-emitting diode (abbreviated as LED), for example, a Mirco LED or a Mini LED.

[0071] It should be noted that during the electrical connection process between the light-emitting device 41 and the driving circuit layer 21, a contact electrode electrically connected to the driving circuit layer 21 can be set, and a relatively large contact hole is opened in the spacer layer 22 to expose the contact electrode, so that the contact electrode has a relatively large contact surface for connecting the light-emitting device 41, which is beneficial to the installation of the light-emitting device 41.

[0072] In some examples, each touch electrode 130 is provided with a plurality of first openings K1, and three consecutive first openings K1 may constitute an opening unit, in which three light-emitting devices 41 with different luminous colors may be provided. The three light-emitting devices 41 with different luminous colors may respectively emit red light, blue light, and green light, so that the light-emitting devices 41 in the opening unit may together constitute a pixel unit. One or more opening units may be provided on each touch electrode 130. When a plurality of opening units are provided, the plurality of opening units may be arranged in an array. In this case, by controlling the light emission of the light-emitting device 41, color display of the display panel 100 may be achieved.

[0073] In some embodiments, please refer to Figure 3 and Figure 6 The display panel 100 further includes a covering layer 14 located on a side of the second touch layer 13 away from the insulating layer 12. The covering layer 14 has a second opening K2 at a position corresponding to the first opening K1. The covering layer 14 covers the edge of the first opening K1. The light emitting device 41 is at least partially located in the second opening K2.

[0074] In this way, the covering layer 14 can be used to cover the portion of the touch electrode 130 at the edge of the first opening K1, thereby effectively preventing the portion of the touch electrode 130 at the edge of the first opening K1 from making electrical contact with the light emitting device 41 located in the second opening K2.

[0075] In some embodiments, Figure 3 and Figure 4 As shown, when the first touch layer 11 includes a reflective structure 112, a third opening K3 is formed in the reflective structure 112. A fourth opening K4 is formed in the insulating layer 12 at a position corresponding to the third opening K3, and the insulating layer 12 covers the edge of the third opening K3. The light emitting device 41 passes through the second opening K2 and the fourth opening K3 and is electrically connected to the driving circuit layer.

[0076] In this configuration, the insulating layer 12 covers the portion of the reflective structure 112 at the edge of the third opening K3, thereby effectively preventing the portion of the reflective structure 112 at the edge of the third opening K3 from making electrical contact with the light emitting device 41 partially located in the fourth opening K4.

[0077] To further illustrate the structure of the display panel 100 in the embodiment of the present application, Figure 7 As shown, the driving circuit layer 21 may include a pixel circuit, the pixel circuit includes a thin film transistor, and the light emitting device 41 is electrically connected to the source or drain of the thin film transistor to realize the input of the driving signal.

[0078] As an example, the driving circuit layer 21 is disposed on a substrate. The substrate may include a substrate 211 and a buffer layer 212, and the substrate may be made of a glass material.

[0079] The thin-film transistor includes an active layer, a gate, a source, and a drain located on the substrate. The film layer where the active layer is located is the semiconductor layer 213, the film layer where the gate is located is the gate layer 215, and the film layers where the source and the drain are located are the source-drain electrode layer 218. A gate insulating layer 214 is provided between the semiconductor layer 213 and the gate layer 215, and at least one interlayer insulating layer is provided between the gate layer 215 and the source-drain electrode layer 218. The interlayer insulating layer may include a first interlayer insulating layer 216 and a second interlayer insulating layer 217.

[0080] The thin-film transistor may be a top-gate transistor, a bottom-gate transistor, or a double-gate transistor, and the embodiments of the present application do not limit this.

[0081] In some examples, a first passivation layer 219 and a first planarization layer 220 are sequentially provided on the side of the source-drain electrode layer 218 away from the substrate. A transfer electrode 221 is provided on the side of the planarization layer 220 away from the source-drain electrode layer 218. The transfer electrode 221 may be electrically connected to the drain of the thin-film transistor through a via hole. A contact electrode 224 is further provided on the side of the transfer electrode 221 away from the source-drain electrode layer 218. A second passivation layer 222 and a second planarization layer 223 are provided between the contact electrode 224 and the transfer electrode 221. The contact electrode 224 is electrically connected to the transfer electrode 221 through a via hole. In addition, the spacer layer 22 may expose a part of the contact electrode 224, thereby facilitating the connection between the light-emitting device 41 and the contact electrode 224.

[0082] As an example, insulating layers such as the buffer layer 212, the gate insulating layer 214, and the interlayer insulating layer may be made of inorganic insulating materials such as silicon nitride, silicon oxide, or silicon oxynitride; the first planarization layer 220 and the second planarization layer 223 may be made of organic insulating materials; in addition, metal layers such as the gate layer 215 and the source-drain electrode layer 218 may be made of metal conductive materials such as molybdenum and indium tin oxide.

[0083] In some embodiments, as Figure 5 and Figure 8 shown, the display panel 100 further includes a control circuit 32. The driving circuit layer 21 and the touch trace 110 are respectively electrically connected to the control circuit 32, and the control circuit 32 is configured to alternately output a touch signal and a display signal.

[0084] In this case, the control circuit 32 is an integrated chip integrating a display function and a touch function, which can improve the integration degree of the display panel 100, thereby facilitating the reduction of the size of the display panel 100.

[0085] As an example, asFigure 8 As shown Figure 8 Figure 8 shows the driving timing of a frame of display image of the display panel 100. In a frame display period of the display panel 100, it includes a display period and a touch period, and the display period and the touch period appear alternately. For example, a frame display period may include at least two display periods and at least two touch periods, and the number of the display periods and the touch periods is equal and they appear alternately.

[0086] In some examples, the durations of the display period and the touch period may be equal or different.

[0087] Some embodiments of the present application provide a display device, and the display device includes the display panel described in any of the above embodiments.

[0088] Due to including the display panel, the display device has the technical effects possessed by the above display panel, which will not be elaborated here.

The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
