It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

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

Referring to fig. 1 to 6, an embodiment of the present application discloses a display module applied to an electronic device, and the 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 sequentially stacked, and a portion of the pixel units 210 of the pixel layer 200 is disposed opposite to the light incident side of the light guide plate 300, and at this time, light emitted from the pixel units 210 opposite to the light incident side of the light guide plate 300 enters the light guide plate 300 from the light incident side. The photosensitive device 400 is disposed on a 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 incident on the light guide plate 300 is transmitted through the light guide plate 300, and is emitted from the light emitting side of the light guide plate 300, and is incident on the light sensing device 400.

In the above embodiment, the photosensitive device 400 has two arrangements, one is disposed between the first substrate 100 and the pixel layer 200, as shown in fig. 1, to be disposed on the surface of the first substrate 100 facing the side of the light guide plate 300. As shown in fig. 2, the other is disposed on a surface of the pixel layer 200 facing a side of 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 meanwhile, structures such as a thin film transistor and a trace line for driving the pixel layer 200 may also be disposed on the first substrate 100. The light sensing device 400 may be a light sensor, a photoelectric converter, or the like, and the light sensing device 400 performs photoelectric conversion first, so that photocurrent data of light emitted by the display module can be obtained.

In the embodiment of the present application, the light sensing device 400 receives the light emitted from the pixel layer 200 through the light guide plate 300, and the light sensing device 400 detects photocurrent data corresponding to the light emitted from the pixel layer 200, where the photocurrent data is compared with standard photocurrent data, where the standard photocurrent data refers to photocurrent data corresponding to a white point coordinate. When the photocurrent data obtained by the light sensing 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, and the display effect of the display module is improved.

According to the conventional optical knowledge, the pixel unit 210 of the display module generally includes three pixel units 210 of red, green and blue, and the three pixel units are superimposed to form white light by selecting different light intensities. The ratio of the luminous intensities of the pixel units 210 of three colors of red, green and blue is generally 3: 6: 1. the photocurrent converted from light of different luminous intensities varies in magnitude.

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

In addition, in this scheme, photocurrent data detected by the light sensing device 400 can also be fed back to a camera module of the electronic device to calibrate the color of a picture taken 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 fed back photoelectric flow data, so that the picture does not have the effect of reddish appearance, and the shooting quality of the picture is improved.

In another alternative embodiment, the light incident side and the light exiting side of the light guide plate 300 may be provided with the gratings 310, the gratings 310 may be located on the surface of the side away from the pixel layer 200, and the gratings 310 located on the light incident side are disposed opposite to part of the pixel units 210. The grating 310 on the light exit side is disposed opposite to the light sensing device 400. In this embodiment, the grating 310 can change the propagation path of the light, so that the amount of the light received by the photosensitive device 400 can be increased, thereby increasing the detection accuracy of the photosensitive device 400.

Optionally, the reflection angle of light can be changed by adjusting parameters such as the screen duty ratio, the depth, the duty ratio, and the like of the grating 310, so as to change the propagation direction of light, and then the grating 310 is reasonably arranged on the light guide plate 300, which belongs to the protection range of the scheme.

In the above embodiment, the ambient light can penetrate through the grating 310 on the light emitting side, and then enter the light guide plate 300 and then enter the light sensing device 400, so that the light sensing device 400 can also detect the photocurrent of the ambient light. At this moment, light sensing device 400 can also detect ambient light to obtain the light and shade change of external environment according to ambient light's photocurrent, thereby adjust display module's luminance, further improved display module's performance.

In the specific operation process, when the display module does not display, the display module does not emit light, so that the photocurrent of the external environment light can be collected; when the display module emits light, the photocurrent of the ambient light and the photocurrent of the light emitted by the display module are collected simultaneously. 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 does not emit light, so that the photocurrent of the light emitted by the display module can be obtained.

In another alternative embodiment, the photosensitive device 400 may be located between the first substrate 100 and the pixel layer 200 and on a surface of the first substrate 100 on a side facing the light guide plate 300. The pixel layer 200 is provided with a black matrix 220 and a pixel unit 210, the pixel unit 210 and the black matrix 220 are embedded, the black matrix 220 is provided with a light hole 221, the light hole 221 can be arranged opposite to the light emitting side of the light guide plate 300, and the photosensitive device 400 is arranged opposite to the light hole 221.

In this scheme, the light sensing device 400 can be disposed between the first substrate 100 and the pixel layer 200, so that the light sensing device 400 can be prevented from colliding with other components, and meanwhile, in order to prevent the black matrix 220 on the pixel layer 200 from shielding light, the black matrix 220 is provided with the light transmission hole 221, so that the light emitted from the light guide plate 300 can penetrate through the light transmission hole 221 and enter the light sensing device 400, and further, the optical performance of the light sensing device 400 is improved.

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

Based on this, in another alternative embodiment, the light guide plate 300 may include a first color light guide plate 310, a second color light guide plate 320, and a third color light guide plate 330, and the first color light guide plate 310, the second color light guide plate 320, the third color light guide plate 330, and the pixel layer 200 are sequentially stacked. The first color light guide plate 310, the second color light guide plate 320, and the third color light guide plate 330 may guide light of a color corresponding to the pixel layer 200 into the photosensitive device 400. In this scheme, the light guide plate 300 of different colours can propagate the light of different colours to can be easier detect alone the photocurrent of every colour, thereby improve and detect the precision, further improve display module's compensation precision.

It should be noted that the first color light guide plate 310 can only transmit the light of the corresponding color, and the light of the color not corresponding to the light can pass through the first color light guide plate 310. For example, the first color light guide plate 310 can transmit red light, and blue 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, and thus are not described herein again.

Alternatively, the first color light guide plate 310 may transmit red light, the second color light guide plate 320 may transmit green light, and the second color light guide plate 320 may transmit blue light. Of course, the first color light guide plate 310, the second color light guide plate 320 and the third color light guide plate 330 may also transmit other colors of light, and the disclosure is not limited thereto.

Further, the light sensing device 400 may include a first color light sensing unit 401, a second color light sensing unit 402, and a third color light sensing unit 403. The first color light unit is used for receiving the light guided by the first color light guide plate 310. The second color photosensitive unit 402 may be used to receive the light introduced by the second color light guide plate 320. The third color photosensitive unit 403 may be used to receive light guided by the third color light guide plate 330. In this scheme, each colour light guide plate corresponds a colour sensitization unit, consequently can detect the photocurrent of every colour alone to make the photocurrent of measuring more accurate, further improve and detect the precision.
