[0039] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0040] As people's quality of life improves, their demands for display quality are also increasing. Wide color gamut, high contrast, high refresh rate, and multi-level brightness and color temperature adjustment are all trends in future display development. Color temperature is an indicator of display color tone. Lower color temperatures indicate warmer tones, while higher color temperatures indicate cooler tones. Setting the appropriate display color temperature can significantly improve viewing quality.

[0041] However, even if the display is set to the same color temperature under different ambient light conditions, it will appear different to the human eye, resulting in problems such as color difference. To improve the user's viewing experience, the display color temperature needs to be adjusted according to different ambient light conditions. Therefore, identifying the ambient light type becomes an important factor in adjusting the display color temperature.

[0042] In related technologies, in order to reduce the power consumption of the display panel and improve eye comfort, a photosensor is set in the display panel and the type of ambient light is calculated through algorithm processing. The display color temperature is then adjusted according to the type of ambient light. However, the detection method using the photosensor cannot distinguish between ambient light with similar spectra.

[0043] Figure 1 1 is a cross-sectional view of a display panel 10 according to an embodiment of the present application, Figure 2 Shows a top view of an embodiment of the present application, see Figure 1 and Figure 2 The embodiment of the present application provides a display panel 10, which is divided into a display area and a non-display area, wherein the non-display area surrounds the display area. The display panel 10 includes a base substrate and a photosensitive module 100.

[0044] For example, the base substrate may be an inorganic material or an organic material; of course, it may also be a composite substrate formed by laminating an inorganic material and an organic material. For example, in some embodiments of the present application, the base substrate may be made of glass materials such as soda-lime glass, quartz glass, and sapphire glass.

[0045] The photosensitive module 100 is disposed on one side of the substrate and in the non-display area. The photosensitive module 100 includes a plurality of first color resists 110, a plurality of first photosensitive transistors 120, a second color resist 130, and a second photosensitive transistor 140. The plurality of first color resists 110 and the plurality of first photosensitive transistors 120 are disposed in a one-to-one correspondence, and the first color resist 110 is disposed on the side of the corresponding first photosensitive transistor 120 facing away from the substrate; the second color resist 130 and the second photosensitive transistor 140 are disposed in a corresponding manner, and the second color resist 130 is disposed on the side of the second photosensitive transistor 140 facing away from the substrate;

[0046] The first color resist 110 is configured to transmit any one of the three primary colors of ambient light, and the first photosensitive transistor 120 is configured to detect the primary color light transmitted through the corresponding first color resist 110 and generate a first electrical signal. The second color resist 130 is configured to transmit mixed light in the ambient light, where the wavelength range of the mixed light is the intersection of the wavelength ranges of two of the three primary colors, and the second photosensitive transistor 140 is configured to detect the mixed light transmitted through the second color resist 130 and generate a second electrical signal.

[0047] Since the ambient light emitted by different types of light sources is obtained by mixing different amounts of the three primary colors of red, green, and blue, and the three primary colors of light pass through color resistors of different colors, the induced current generated by the first photosensitive transistor 120 is also different. Therefore, the type of ambient light can be determined by the detection amount of the first photosensitive transistor 120 corresponding to the different color resistors.

[0048] For example, Figure 3 FIG. 4 is a schematic diagram showing the spectrum of ambient light passing through the color filter layer 400 according to an embodiment of the present application, see FIG. Figure 3When the first color resist 110 transmits green primary light, after the ambient light passes through the color filter of the display panel 10 and the first color resist 110, the wavelength of the green primary light detected by the first photosensitive transistor 120 is 470nm to 640nm. When the first color resist 110 transmits blue primary light, after the ambient light passes through the color filter of the display panel 10 and the first color resist 110, the wavelength of the blue primary light detected by the first photosensitive transistor 120 is 380nm to 548nm. When the first color resist 110 transmits red primary light, after the ambient light passes through the color filter of the display panel 10 and the first color resist 110, the wavelength of the red primary light detected by the first photosensitive transistor 120 is 580nm to 800nm. Since the wavelengths of the green primary light, the blue primary light, and the red primary light overlap slightly, when the first color resist 110 transmits the blue primary light, it also transmits the green primary light whose wavelength overlaps with the blue primary light. When the first color resist 110 transmits the red primary light, it also transmits the green primary light whose wavelength overlaps with the red primary light. This makes the detection result of the first photosensitive transistor 120 inaccurate, resulting in the inability to accurately distinguish different types of light sources when performing algorithm processing based on the first electrical signal.

[0049] It is understood that the algorithm processing can be the ADC ratio of different color channels, for example, the ratio of the blue channel to the green channel (B / G), the ratio of the red channel to the green channel (R / G), and the ratio of the red channel to the blue channel (R / B). It should be noted that the algorithm processing can also be other calculation methods for detecting and distinguishing different types of ambient light, such as determining the type of ambient light based on the ratio of the detection amount corresponding to the first photosensitive transistor 120 and the second photosensitive transistor 140. It should be noted that the specific calculation method is not involved in the embodiments of this application and is not described in detail here.

[0050] It should be noted that the wavelength of the green primary light overlaps with the blue primary light and the red primary light, so the second color resist 130 can transmit the green primary light and the blue primary light, or the green primary light and the red primary light.

[0051] In the display panel 10 according to the embodiment of the present application, the first photosensitive transistor 120 detects the primary light transmitted through the first color resist 110 and generates a first electrical signal, while the second photosensitive transistor 140 detects the mixed light transmitted through the second color resist 130 and generates a second electrical signal. For example, in the case where the first color resist 110 transmits blue primary light and the second color resist 130 transmits the overlapping portion of the wavelengths of the blue and green primary lights, the first photosensitive transistor 120 detects the blue primary light transmitted through the first color resist 110 and generates a first electrical signal, while the second photosensitive transistor 140 detects the overlapping portion of the wavelengths of the blue and green primary lights transmitted through the second color resist 130 and generates a second electrical signal. The second electrical signal includes the spectral characteristics of the overlapping portion of the wavelengths of the blue and green primary lights. The second electrical signal is then compared with the first electrical signal to identify the type of ambient light, thereby determining the type and spectrum of the light source, further accurately identifying the ambient light and improving the accuracy of ambient light recognition.

[0052] Among them, the light source includes A light source, D65 light source, CWF light source, U30 light source, and LED light source, etc. The photosensitive module 100 of the present application is used to determine the type of the above light source.

[0053] It should be noted that when receiving ambient light, the photosensitive transistor converts the ambient light into an electrical signal. Specifically, when the gate 216 of the photosensitive transistor receives a first control signal, the gate 216 of the photosensitive transistor is set to a closed state. When exposed to light, the voltage output by the drain 215 of the photosensitive transistor increases. The voltage change is read as a light-sensing signal. Based on the response results to different wavelengths and the spectral characteristics of common ambient light, the ambient light emitted by different light sources can be identified.

[0054] In some embodiments, the present application also includes a processing module, which electrically communicates with the photosensitive module. The processing module determines the type of ambient light based on the first electrical signal and / or the second electrical signal. The processing module is used to compare the second electrical signal with the first electrical signal, thereby identifying the type of ambient light, thereby accurately identifying the corresponding light source and spectrum, and further realizing accurate identification of the light source.

[0055] In some embodiments, see Figure 1 The second color resist 130 includes a first sub-color resist 131 and a second sub-color resist 132 , and the first sub-color resist 131 and the second sub-color resist 132 are adjacent to each other along a direction perpendicular to the substrate.

[0056] One of the first sub-color resist 131 and the second sub-color resist 132 is configured to transmit blue primary light, and the other is configured to transmit green primary light. Specifically, the first sub-color resist 131 transmits blue primary light with a wavelength of 470 nm to 548 nm, while the second sub-color resist 132 transmits green primary light with a wavelength of 470 nm to 548 nm. This allows the second photosensitive transistor 140 to detect the overlapping portion of the wavelengths of the blue and green primary light transmitted through the second color resist 130 and generate a second electrical signal.

[0057] In another embodiment, one of the first sub-color resist 131 and the second sub-color resist 132 is configured to transmit green primary light, and the other is configured to transmit red primary light. Specifically, the first sub-color resist 131 transmits green primary light with a wavelength of 580 nm to 640 nm, while the second sub-color resist 132 transmits red primary light with a wavelength of 580 nm to 640 nm. This allows the second photosensitive transistor 140 to detect the wavelength of the overlapping portion of the red and green primary light transmitted through the second color resist 130 and generate a second electrical signal.

[0058] Figure 4 A schematic diagram showing the ADC ratio of the second photosensitive transistor 140 corresponding to different light sources, Figure 5 Schematic diagram showing the spectrum of the D65 light source and the LED light source through the color filter layer 400 according to the embodiment of the present application, see Figure 4 and Figure 5 In the related art, when judging the external light source by the ADC ratio (R / B) tested by the red color resist 111 and the blue color resist 113 among the red color resist 111, the green color resist 112, and the blue color resist 113, it is found that the ADC ratio (R / B) of the D65 light source and the LED light source are relatively close, both around 0.9, so it is difficult to distinguish the D65 light source from the LED light source.

[0059] Based on this, see Figure 1 The first sub-color resist 131 is used to transmit the blue primary color light, and the second sub-color resist 132 is used to transmit the green primary color light. The wavelength of the red primary color light is 580nm to 800nm. Figure 5As shown, the energy difference between the D65 spectrum and the LED spectrum in the wavelength band of 480nm to 500nm is relatively large, and 480nm to 500nm is the overlapping wavelength band of the red primary light and the green primary light. Therefore, the present application sets the first sub-color resistor 131 to pass the blue primary light and the second sub-color resistor 132 to pass the green primary light, so that the overlapping part of the green primary light and the blue primary light in the wavelength band of 480nm to 500nm can pass through the first sub-color resistor 131 and the second sub-color resistor 132, so that the second photosensitive transistor 140 can detect the response result of the overlapping part of the green primary light and the red primary light in the wavelength band of 480nm to 500nm passing through the second color resistor 130 and generate a second electrical signal to obtain more spectral characteristics of the overlapping part of the D65 and LED light sources, and then through subsequent algorithm processing, it is possible to identify whether the external ambient light is a D65 light source or an LED light source.

[0060] It is understandable that the colors of the transmitted light of the first sub-color resist 131 and the second sub-color resist 132 of the present application can be selected according to the two different light sources that need to be further accurately identified, and this is not limited here.

[0061] In some embodiments, see Figure 1 and Figure 2 The plurality of first color resists 110 include a red color resist 111, a green color resist 112, and a blue color resist 113. The red color resist 111 is configured to transmit red primary light, the green color resist 112 is configured to transmit green primary light, and the blue color resist 113 is configured to transmit blue primary light. The plurality of first photosensitive transistors 120 include a red photosensitive transistor corresponding to the red color resist 111, a green photosensitive transistor corresponding to the green color resist 112, and a blue photosensitive transistor corresponding to the blue color resist 113. With this configuration, the processing module can determine the type of ambient light based on the first electrical signals corresponding to the red color resist 111, the green color resist 112, and the blue color resist 113.

[0062] The ambient light emitted by different types of light sources can be considered to be obtained by mixing different amounts of red, green, and blue primary colors. In addition, different colors of the three primary colors of light pass through the red color resist 111, the green color resist 112, and the blue color resist 113, resulting in different induced currents or voltages generated by the corresponding first photosensitive transistor 120.

[0063] In some embodiments, a plurality of first color resists 110 and a plurality of first photosensitive transistors 120 are disposed correspondingly, and the orthographic projections of the first photosensitive transistors 120 on the base substrate at least partially overlap with the orthographic projections of the corresponding first color resists 110 on the base substrate, so that the first photosensitive transistors 120 can detect ambient light transmitted through the first color resists 110. The orthographic projections of the second color resists 130 on the base substrate at least partially overlap with the orthographic projections of the second photosensitive transistors 140 on the base substrate, so that the second photosensitive transistors 140 can detect ambient light transmitted through the second color resists 130.

[0064] For example, see Figure 1 The orthographic projection of the red color resist 111 on the substrate at least partially overlaps with the orthographic projection of the corresponding first photosensitive transistor 120 on the substrate. The orthographic projection of the green color resist 112 on the substrate at least partially overlaps with the orthographic projection of the corresponding first photosensitive transistor 120 on the substrate. The orthographic projection of the blue color resist 113 on the substrate at least partially overlaps with the orthographic projection of the corresponding first photosensitive transistor 120 on the substrate.

[0065] In some embodiments, see Figure 1 The photosensitive module 100 further includes a third photosensitive transistor 150 and a black color resist 160. The black color resist 160 is disposed on the side of the corresponding third photosensitive transistor 150 facing away from the substrate. The third photosensitive transistor 150 is used to detect dark-state brightness information, which can serve as a reference value for the first photosensitive transistor 120 and the second photosensitive transistor 140. Specifically, since photosensitive transistors may have leakage current, the third photosensitive transistor 150, the first photosensitive transistor 120, and the second photosensitive transistor 140 are disposed on the same layer. Therefore, it can be determined that the leakage currents of the third photosensitive transistor 150, the first photosensitive transistor 120, and the second photosensitive transistor 140 are consistent. To more accurately control a single variable, the embodiment of the present application uses the detection value of the third photosensitive transistor 150 corresponding to the black color resist 160 as a reference, thereby eliminating the influence of noise and deviation of the first photosensitive transistor 120 and the second photosensitive transistor 140 on the corresponding detection results, thereby obtaining more reliable first and second electrical signals.

[0066] It should be noted that the black color resist 160 absorbs all ambient light. Therefore, the dark-state brightness information output by the third photosensitive transistor 150 is the dark-state background current of the first photosensitive transistor 120 and the second photosensitive transistor 140. Based on this, the first electrical signal output by the first photosensitive transistor 120 and the second electrical signal output by the second photosensitive transistor 140 can be noise-reduced using the dark-state brightness information output by the third photosensitive transistor 150, thereby obtaining more accurate detection results.

[0067] More specifically, the current output by the first photosensitive transistor 120 can be subtracted from the current output by the third photosensitive transistor 150 to obtain an accurate detection result after calibration of the first photosensitive transistor 120; similarly, the current output by the second photosensitive transistor 140 can be subtracted from the current output by the third photosensitive transistor 150 to obtain an accurate detection result after calibration of the second photosensitive transistor 140.

[0068] In some embodiments, see Figure 1 The present application also includes an array substrate 200, a liquid crystal layer 300 and a color filter layer 400. The array substrate 200 is arranged on one side of the base substrate, the liquid crystal layer 300 is arranged on the side of the array substrate 200 away from the base substrate, and the color filter layer 400 is arranged on the side of the liquid crystal layer 300 away from the base substrate.

[0069] The plurality of first photosensitive transistors 120 and second photosensitive transistors 140 are fabricated in the same layer and process as the thin film transistors 210 in the array substrate 200 , thereby simplifying the fabrication process of the first photosensitive transistors 120 and second photosensitive transistors 140 and reducing processing costs.

[0070] In some embodiments, see Figure 1 The thin film transistor 210 includes a thin film transistor substrate 211 , a gate insulating layer 212 , a passivation layer 213 , a source electrode 214 , a drain electrode 215 , and a gate electrode 216 .

[0071] It is understandable that since the first photosensitive transistor 120 and the second photosensitive transistor 140 are manufactured in the same layer and the same process as the thin film transistor 210 in the array substrate 2002 , the first photosensitive transistor 120 and the second photosensitive transistor 140 are also thin film transistors 210 .

[0072] In some embodiments, the first electrical signal and the second electrical signal are voltage signals or current signals.

Therefore, the display module has all the features and advantages of the display panel 10 described above, which will not be repeated here. In general, taking the example of the first color resist 110 transmitting blue primary light and the second color resist 130 transmitting the wavelength overlap portion of the blue primary light and the green primary light, the first photosensitive transistor 120 detects the blue primary light transmitted through the first color resist 110 and generates a first electrical signal, and the second photosensitive transistor 140 detects the wavelength overlap portion of the blue primary light and the green primary light transmitted through the second color resist 130 and generates a second electrical signal. The second electrical signal includes the spectral characteristics of the wavelength overlap portion of the blue primary light and the green primary light. Then, by comparing the second electrical signal with the first electrical signal, the type of external ambient light is identified, and the type and spectrum of the light source are determined, thereby further accurately identifying the ambient light, which is conducive to improving the accuracy of ambient light identification.
