Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work, all belong to the scope of protection of this application.

It is to be understood that data so used may be interchanged under appropriate circumstances so that embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The display module provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Referring to FIGS. 1 to 6 , an embodiment of the present application discloses a display module. The disclosed display module is applied to electronic equipment. The disclosed display module includes a first substrate 100 , a pixel layer 200 , a light guide plate 300 and a Photosensitive device 400 .

The light guide plate 300 , the pixel layer 200 and the first substrate 100 are stacked in sequence, and some pixel units 210 of the pixel layer 200 are disposed opposite to the light incident side of the light guide plate 300 . At this time, the pixel units opposite to the light incident side of the light guide plate 300 The light emitted by 210 enters the light guide plate 300 from the light incident side. The photosensitive device 400 is disposed on the side of the first substrate 100 or the pixel layer 200 facing the light guide plate 300 , and the photosensitive device 400 is disposed opposite to the light-emitting side of the light guide plate 300 . At this time, the light entering the light guide plate 300 is transmitted through the light guide plate 300 and emitted from the light exit side of the light guide plate 300 , and then enters the photosensitive device 400 .

In the above-mentioned embodiment, the photosensitive device 400 has two disposition modes. As shown in FIG. 1 , one is disposed between the first substrate 100 and the pixel layer 200 , so as to be disposed on the side of the first substrate 100 facing the light guide plate 300 . s surface. As shown in FIG. 2 , the other is disposed on the surface of the pixel layer 200 facing the light guide plate 300 . Specifically, the pixel layer 200 may be provided with a groove, and the photosensitive device 400 may be located in the groove.

Optionally, the first substrate 100 is used to carry the pixel layer 200 , and at the same time, structures such as thin film transistors and wires for driving the pixel layer 200 may also be provided on the first substrate 100 . The photosensitive device 400 may be a photo sensor, a photoelectric converter, etc. The photosensitive device 400 performs photoelectric conversion first, so that the photocurrent data of the light emitted by the display module can be obtained.

In the embodiment of the present application, the photosensitive device 400 receives the light emitted by the pixel layer 200 through the light guide plate 300, and the photosensitive device 400 detects the photocurrent data corresponding to the light emitted by the pixel layer 200, and the photocurrent data is compared with the standard photocurrent data. In contrast, the standard photocurrent data refers to the photocurrent data corresponding to the coordinates of the white point. When the photocurrent data obtained by the photosensitive device 400 deviates from the standard photocurrent data, the display module can output a compensation value to compensate the display module, so that the white point coordinates of the display module can be compensated to improve the display module. display effect.

According to the common knowledge related to optics, the pixel unit 210 of the display module generally includes three color pixel units 210 of red, green and blue, and by selecting different luminous intensities, they are superimposed into white light. Generally, the ratio of the luminous intensity of the pixel units 210 of the three colors of red, green and blue is 3:6:1. The magnitude of the photocurrent converted into light with different luminous intensity is different.

In a specific compensation operation, for example, when the detected photocurrent is at a reddish value, the current of the pixel unit 210 that emits red light can be reduced, so that the light intensity of the pixel unit 210 corresponding to the red light is reduced , and then calibrate the white point coordinates of the display module.

In addition, in this solution, the photocurrent data detected by the photosensitive device 400 can also be fed back to the camera module of the electronic device to calibrate the color of the picture captured by the camera module, thereby improving the shooting effect of the camera module. For example, when the picture of the display module is reddish, the camera module can correspondingly reduce the red purity of the picture according to the feedback photocurrent data, so that the picture does not appear to be reddish, so as to improve the shooting quality of the picture.

In another optional embodiment, gratings 310 may be provided on both the light-incident side and the light-exiting side of the light guide plate 300 , and the gratings 310 may be located on the surface of the side away from the pixel layer 200 . Some of the pixel units 210 are arranged opposite to each other. The grating 310 on the light-emitting side is disposed opposite to the photosensitive device 400 . In this solution, the grating 310 can change the propagation path of light, so the amount of light received by the photosensitive device 400 can be increased, thereby improving the detection accuracy of the photosensitive device 400 .

Optionally, by adjusting the screen ratio, depth, duty ratio and other parameters of the grating 310, the reflection angle of the light can be changed to change the propagation direction of the light, and then the reasonable arrangement of the grating 310 on the light guide plate 300 belongs to the protection of this scheme. scope.

In the above embodiment, the ambient light can pass through the grating 310 on the light-emitting side, thereby entering the light guide plate 300, and then entering the photosensitive device 400, so the photosensitive device 400 can also detect the photocurrent of the ambient light. At this time, the photosensitive device 400 can also detect the ambient light, so as to obtain the light and dark changes of the external environment according to the photocurrent of the ambient light, so as to adjust the brightness of the display module and further improve the usability of the display module.

In the specific operation process, when the display module has no display, the display module does not emit light, so the photocurrent of the external ambient light can be collected; when the display module emits light, the photocurrent of the ambient light and the light emitted by the display module are simultaneously collected. photocurrent. Therefore, when the photocurrent of the light emitted by the display module is to be obtained, the photocurrent of the ambient light and the photocurrent of the light emitted by the display module can be subtracted from the photocurrent of the ambient light detected when the display module is not emitting light, and the display module can be obtained.

In the above embodiment, the same light guide plate 300 can transmit the light of all colors of the pixel unit 210 to the sensor. In this way, it is difficult to accurately determine the individual photocurrent of each color, so the detection accuracy is low.

In this solution, the light guide plates 300 of different colors can transmit light of different colors, so that the photocurrent of each color can be easily detected separately, thereby improving the detection accuracy and further improving the compensation accuracy of the display module.

It should be noted that the first color light guide plate 310 can only transmit the light of its corresponding color, and the light of the color not corresponding to the light guide plate 310 can pass through the first color light guide plate 310 . For example, the first color light guide plate 310 can transmit red light, while the blue light and green light can pass through the first color light guide plate 310 . The effects of the second color light guide plate 320 and the third color light guide plate 330 are the same as those of the first color light guide plate 310 , so they will not be described in detail herein.
