With the development of electronic technologies, the screen-to-body ratio of electronic devices such as smart phones is getting larger and larger, and the area on the display screen of the electronic device for arranging electronic components such as sensors is getting smaller and smaller. Therefore, on more and more electronic devices, the ambient light sensor is arranged under the display screen to detect the brightness of the ambient light through the ambient light sensor.

[0003] Since ambient light includes visible light with wavelengths in the range of 380 - 780 nanometers and non-visible light with wavelengths outside the range of 380 - 780 nanometers, for an ambient light sensor, only the visible light with wavelengths in the range of 380 - 780 nanometers is the effective sensing light wave, and the non-visible light with wavelengths outside the range of 380 - 780 nanometers will affect the detection result of the ambient light sensor, and further affect the dimming effect of the display screen.

However, the present application can be specifically implemented in many alternative forms and should not be construed as being limited only to the embodiments set forth herein.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] Figure 1 This is a display panel provided by the first embodiment of the present application. As Figure 1 shown, the display panel 100 includes an infrared light detection module 200, a light intensity calculation module 300, and a control module 400. The infrared light detection module 200 is used to detect the intensity of infrared light in ambient light. The light intensity calculation module 300 is connected to the infrared light detection module 200 and calculates the intensity of visible light in ambient light according to the detection result of the infrared light detection module 200. The control module 400 is connected to the light intensity calculation module 300 and controls the display brightness of the display panel 100 according to the intensity of visible light in ambient light.

[0028] Compared with the current design of directly detecting the ambient light brightness through an ambient light sensor and then performing dimming, in the embodiment of the present application, the infrared light detection module 200 is used to detect the intensity of infrared light in ambient light, and then the light intensity calculation module 300 calculates the intensity of visible light in the corresponding ambient light according to the detected intensity of infrared light, so that the control module 400 can control the display brightness of the display panel 100 only according to the intensity of visible light in ambient light, thereby avoiding the interference of invisible light in ambient light on the ambient light sensor, improving the detection accuracy of ambient light brightness, and improving the dimming effect of the display panel 100.

[0029] Compared with other non-visible lights, infrared light has weak scattering, stronger penetrability, and a relatively large proportion in ambient light. Using infrared light to calculate visible light has better stability and detection effect.

[0030] In the embodiment of the present application, the infrared light detection module 200 is an infrared light sensor 210, which directly detects the intensity of infrared light in the detected ambient light by using the infrared light sensor 210.

[0031] Among them, the infrared light sensor 210 adopts a thin-film transistor structure and is synchronously fabricated with the switches of pixels in the display panel 100 to reduce the manufacturing process of the display panel 100. Of course, in other embodiments, the infrared light sensor 210 can also be attached to the display panel 100 by using a chip mounting process, or fabricated inside the display panel 100 by using other structural designs.

[0032] In the embodiment of the present application, the light intensity calculation module 300 and the control module 400 can be integrated in the driving circuit of the display panel 100 to improve the integration degree of the driving circuit 600. Since ambient light is composed of multiple visible lights and multiple non-visible lights, and infrared light is only one of the ambient lights and has a relatively large proportion in ambient light, generally about 43%, the intensity of visible light can be calculated based on the proportion of infrared light in ambient light and the detection result of infrared light.

[0033] Moreover, since infrared light is affected by conditions such as time and air quality, the light intensity calculation module 300 can synchronously receive the information of the weather software and time software in the display panel 100 to adjust the proportion of infrared light in ambient light under the current conditions, thereby improving the calculation accuracy of the visible light intensity.

[0034] In the embodiment of the present application, the display panel 100 can be a liquid crystal panel, an organic electroluminescent display panel 100, or other types of display panels. When the display panel 100 is a liquid crystal panel, the control module 400 directly adjusts the light output brightness of the backlight module in the display panel 100; when the display panel 100 is an organic electroluminescent display panel 100, the control module 400 directly adjusts the self-luminous brightness of the display panel 100.

[0035] Figure 2 This is a display panel provided by the second embodiment of the present application, as Figure 2As shown, compared with the first embodiment, the infrared light detection module 200 in the embodiment of the present application is composed of a feedback unit 220 and at least one variable resistance unit 230. The variable resistance unit 230 is used to receive ambient light, and the resistance value of the variable resistance unit 230 changes with the intensity of infrared light in the ambient light. The feedback unit 220 is respectively connected to the variable resistance unit 230 and the light intensity calculation module 300, and outputs a corresponding infrared light intensity value according to the resistance value of the variable resistance unit 230. The light intensity calculation module 300 calculates the intensity of visible light in the ambient light according to the infrared light intensity value.

[0036] In the embodiment of the present application, the infrared light intensity is detected by the variable resistance unit 230 and the feedback unit 220. Compared with the solution of directly detecting the infrared light intensity by using an infrared sensor, the solution of the embodiment of the present application has higher detection accuracy.

[0037] In the embodiment of the present application, the variable resistance unit 230 includes an elastomeric fiber membrane 240 and a connection component 250. One end of the connection component 250 receives an electrical signal V1, and the other end of the connection component 250 is connected to the feedback unit 220. The elastomeric fiber membrane 240 and the connection component 250 are correspondingly arranged. The elastomeric fiber membrane 240 has elasticity, and the extension size of the elastomeric fiber membrane 240 is proportional to the intensity of infrared light in the ambient light.

[0038] Among them, the electrical signal V1 is a constant voltage or constant current signal provided by the driving circuit.

[0039] Specifically, the elastomeric fiber membrane 240 is a dielectric liquid crystal elastomeric fiber membrane, and the dielectric liquid crystal elastomeric fiber membrane includes alternately arranged rigid liquid crystal units and flexible spacer groups. When the dielectric liquid crystal elastomeric fiber membrane is irradiated with infrared light, the dielectric liquid crystal elastomeric fiber membrane will perform microscopic stretching and shrinking movements. The rigid liquid crystal units subjected to stretching will be oriented under force, thereby forming an ion channel to change the conductivity of the dielectric liquid crystal elastomeric fiber membrane. Among them, the intensity of infrared light is proportional to the stretching degree of the dielectric liquid crystal elastomeric fiber membrane, and the stretching and shrinking process of the dielectric liquid crystal elastomeric fiber membrane is reversible. Of course, in other embodiments, the elastomeric fiber membrane 240 can also adopt other deformation structures, and even the variable resistance unit 230 can adopt other structures that do not deform, such as infrared photoresistors, etc.

[0040] In an embodiment of the present application, the connection component 250 includes a first connection segment 251 and a second connection segment 252. One end of the first connection segment 251 receives an electrical signal, and the other end of the first connection segment 251 is connected to the elastomeric fiber membrane 240; one end of the second connection segment 252 is connected to the elastomeric fiber membrane 240, and the other end of the second connection segment 252 is connected to the feedback unit 220. Through the above design, a path is formed among the first connection segment 251, the elastomeric fiber membrane 240, and the second connection segment 252. When the elastomeric fiber membrane 240 is irradiated by ambient light or the infrared light intensity changes, the resistance value of the elastomeric fiber membrane 240 will change, causing the electrical signal output by the second connection segment 252 to the feedback unit 220 to decrease. The feedback unit 220 outputs a corresponding infrared light intensity value according to the relationship or calculation formula between the internal stored current (or voltage) and the infrared light intensity. The embodiment of the present application can adjust the brightness of the display panel 100 in real time according to the infrared light intensity to improve the dimming effect.

[0041] Further, as Figure 3 shown, the infrared light detection module 200 includes a first variable resistance unit 260 and a second variable resistance unit 270. A shielding layer 500 is provided above the first variable resistance unit 260, and the shielding layer 500 is used to shield ambient light; the upper part of the second variable resistance unit 270 is transparent and unobstructed, and the second variable resistance unit 270 can receive ambient light; the feedback unit 220 is connected to both the first variable resistance unit 260 and the second variable resistance unit 270, and outputs a corresponding infrared light intensity value according to the resistance values of the first variable resistance unit 260 and the second variable resistance unit 270. Through the above design, since the first variable resistance unit 260 and the second variable resistance unit 270 are the same in all other conditions except for external light irradiation, the feedback unit 220 uses the difference between the first variable resistance unit 260 and the second variable resistance unit 270 to obtain the detection result of the infrared light detection module 200 only for the infrared light intensity, avoiding interference caused by conditions such as temperature to the infrared light detection module 200.

[0042] Specifically, taking a liquid crystal panel as an example, the display panel 100 includes an array substrate and a color filter substrate arranged opposite to each other. The first variable resistance unit 260 and the second variable resistance unit 270 are arranged in the non-display area of the array substrate, and a light-shielding layer for preventing light leakage is provided in the non-display area of the color filter substrate. By digging a hole in the light-shielding layer above the second variable resistance unit 270 to expose the second variable resistance unit 270 below, the elastomeric fiber membrane 240 in the second variable resistance unit 270 can receive ambient light.

[0043] It should be noted that, at the bottom of the first variable resistor unit 260 and the second variable resistor unit 270, that is, on the side facing the backlight module, a light shielding structure may not be provided, or a light shielding structure may be provided, so that the first variable resistor unit 260 and the second variable resistor unit 270 are affected by the backlight in the same way and have the same backlight conditions, thereby avoiding the interference of the backlight on the detection.

[0044] In some embodiments, the first connecting line segment 251 and the second connecting line segment 252 are deposited on the array substrate, and can be carried out synchronously with the original metal structure manufacturing process on the array substrate to improve production efficiency. The elastomeric fiber film 240 is disposed on the first connecting line segment 251 and the second connecting line segment 252, covering a part of the first connecting line segment 251 and a part of the second connecting line segment 252. When the elastomeric fiber film 240 is irradiated by ambient light, the elastomeric fiber film 240 extends above the first connecting line segment 251 and the second connecting line segment 252, without affecting the stability of the first connecting line segment 251 and the second connecting line segment 252, and at the same time ensuring a large connection area between the elastomeric fiber film 240 and the first connecting line segment 251 and the second connecting line segment 252 to prevent connection detachment. Among them, the elastomeric fiber film 240 can be disposed on the first connecting line segment 251 and the second connecting line segment 252 through a coating process.

[0045] Figure 4 This is a display panel provided by the third embodiment of the present application. As Figure 4 shown, compared with the second embodiment, the connection component 250 in the embodiment of the present application adopts another design. Specifically, the connection component 250 includes at least two test lines 253, the test lines 253 are arranged in parallel with the elastomeric fiber film 240, and along the direction away from the elastomeric fiber film 240, the test lines 253 are arranged in sequence; when the intensity of infrared light in the ambient light reaches a threshold value, the elastomeric fiber film 240 is connected to the connection component 250; one end of the at least two test lines 253 receives the same electrical signal V1, and the other ends of the at least two test lines 253 are respectively connected to the feedback unit 220.

[0046] Adopting the design of the embodiment of the present application, the intensity of infrared light is divided into corresponding levels according to the number of test lines 253. Taking the connection component 250 having three test lines 253 as an example, the three test lines 253 are divided into an inner test line 254, a middle test line 255, and an outer test line 256 according to the distance from the elastomeric fiber film 240.

[0047] When the elastomeric fiber membrane 240 is irradiated by ambient light and the infrared light reaches the first level, the elastomeric fiber membrane 240 extends to contact the test line 253 (inner test line 254) closest in distance. At this time, the electrical signal passes through the inner test line 254 and the elastomeric fiber membrane 240. Since the elastomeric fiber membrane 240 has a certain resistance, the electrical signal finally output by the inner test line 254 will change, while the electrical signals output by the other test lines 253 do not change. At this time, the feedback unit 220 identifies that the elastomeric fiber membrane 240 has extended to the first level based on the output results of the three test lines 253, and only needs to control the brightness of the display panel 100 to the corresponding brightness level. When the infrared light reaches the second level, the elastomeric fiber membrane 240 extends to contact the middle test line 255. At this time, the electrical signals of both the inner test line 254 and the middle test line 255 pass through the elastomeric fiber membrane 240, resulting in changes in the electrical signals output by both the inner test line 254 and the middle test line 255. At this time, only the electrical signal passing through the outer test line 256 does not change. The feedback unit 220 identifies that the elastomeric fiber membrane 240 has extended to the second level based on the output results of the three test lines 253, and only needs to control the brightness of the display panel 100 to the corresponding brightness level. When the infrared light reaches the third level, the elastomeric fiber membrane 240 extends to contact the test line 253 (outer test line 256) farthest in distance. At this time, the electrical signals of the inner test line 254, the middle test line 255, and the outer test line 256 all pass through the elastomeric fiber membrane 240, resulting in changes in the electrical signals output by the inner test line 254, the middle test line 255, and the outer test line 256. At this time, the feedback unit 220 identifies that the elastomeric fiber membrane 240 has extended to the third level based on the output results of the three test lines 253, and only needs to control the brightness of the display panel 100 to the corresponding brightness level.

[0048] The elastomeric fiber membrane 240 is relatively sensitive to infrared light. When the infrared light changes slightly, it can correspondingly change its own resistivity. In this way, if the design of the second embodiment is adopted, the display panel 100 can adjust the light output brightness of the display panel 100 in real time according to the change of the elastomeric fiber membrane 240, achieving a good display effect. However, this will increase the computational difficulty of the chip, increase the requirements for the chip, and make the cost of the chip and the display product higher.

[0049] With the design of the embodiment of the present application, when there is weak ambient light or the degree of ambient light change is small, the elastomeric fiber membrane 240 undergoes slight extension, but does not contact any of the test lines 253. At this time, the output results of the three test lines 253 received by the feedback unit 220 do not change, and at this time, the brightness of the display panel 100 does not need to be changed; only when the elastomeric fiber membrane 240 extends to a certain extent, that is, when it contacts the inner test line 254, the middle test line 255, or the outer test line 256, will the brightness of the display panel 100 be adjusted. In the embodiment of the present application, the display panel 100 does not need to adjust the brightness for slight changes in infrared light intensity, nor does it need to perform dimming calculations. It only needs to divide into several fixed dimming levels. Therefore, the requirements for the chip are relatively low, which is beneficial to reducing the costs of the chip and the display product.

[0050] It should be noted that the embodiment of the present application does not limit the number of test lines 253. If it is necessary to improve the dimming accuracy, the number of test lines 253 can be increased to four or more, so that the display panel 100 has more dimming levels; if it is necessary to reduce the dimming accuracy, the number of test lines 253 can be reduced to two, so that the display panel 100 only has two dimming levels, making the requirements for the chip the lowest. The above can be selected according to the actual situation and is not limited here.

[0051] It should be noted that since the elastomeric fiber membrane 240 has elasticity, when the elastomeric fiber membrane 240 encounters the obstruction of the test line 253 during extension, it will adjust the extension direction and extend outward across the test line 253. Therefore, it will not generate a large extrusion force with the test line 253, resulting in the deformation or detachment of the test line 253. To further improve the extension ability of the elastomeric fiber membrane 240, the embodiment of the present application also increases the height of the elastomeric fiber membrane 240 so that the elastomeric fiber membrane 240 is higher than the test line 253. Specifically, the height of the elastomeric fiber membrane 240 can be set to twice the height of the test line 253, making it easier for the elastomeric fiber membrane 240 to cross the test line 253.

[0052] Further, in the embodiments of the present application, the test line 253 is in a broken line shape or a semi-circular shape, and each test line 253 surrounds at least three sides of the elastomeric fiber membrane 240. Due to factors such as gravity and the non-uniformity of infrared light, the degree of extension of the elastomeric fiber membrane 240 in each direction is not uniform. In some directions, the extension size is larger, and in some directions, the extension size is smaller. To prevent the elastomeric fiber membrane 240 from extending to a preset degree but not contacting the test line 253, the test line 253 is designed in a semi-circular shape in the embodiments of the present application, so that the test line 253 surrounds the elastomeric fiber membrane 240. At this time, even if the elastomeric fiber membrane 240 extends in a certain direction, it will contact the test line 253, thereby improving the test accuracy. Of course, in other embodiments, the test line 253 can also be in a straight line shape, an L shape, a C shape, etc., and can be specifically selected according to actual situations.

[0053] As Figure 5 and Figure 6 shown, as a further implementation manner, similar to the second embodiment, in order to avoid the interference caused by conditions such as temperature to the infrared light detection module 200 and improve the detection effect, in the embodiments of the present application, the infrared light detection module 200 also includes a first variable resistance unit 260 and a second variable resistance unit 270. A shielding layer 500 is provided above the first variable resistance unit 260, and the shielding layer 500 is used to shield ambient light; the upper part of the second variable resistance unit 270 is transparent to receive ambient light; the feedback unit 220 is connected to both the first variable resistance unit 260 and the second variable resistance unit 270, and outputs a corresponding infrared light intensity value according to the resistance values of the first variable resistance unit 260 and the second variable resistance unit 270.

[0054] As Figure 7 shown, the present application also discloses a display device 10, which includes a driving circuit 600 and the display panel 100 as described in the above embodiments, and the driving circuit 600 is used to drive the display panel 100.

[0055] The above content is a further detailed description of the present application in combination with specific optional implementation manners. It cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present application.
