Fig. 2 is a schematic top view of a display screen in an evaluation method of the display screen according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of a display screen and an off-screen device according to an embodiment of the present invention. Specifically, the evaluation method of the display screen comprises the following steps:
s10: at least one first display parameter in a first display area of the display screen and at least one second display parameter in a second display area of the display screen are acquired.
As can be seen in fig. 2, the display screen 100 includes a first display area 10 and a second display area 20 adjacent to each other, and in particular, the second display area 20 is disposed around the first display area 10.
In one embodiment, the first display area 10 of the display screen 100 corresponds to the off-screen device 30 of the display screen 100; preferably, the underscreen device 30 comprises a camera, see in particular fig. 3.

Specifically, a display difference quantization value of the display screen is obtained through a series of operations according to the acquired first display parameter and the acquired second display parameter.
S30: and evaluating the display effect of the display screen according to the display difference quantization value.
Specifically, whether the display effect of the display screen is qualified or not is evaluated according to the display difference quantization value obtained through the operation.
In one embodiment, the first display parameter and the second display parameter include at least one of a brightness, a color coordinate, or a color temperature. Various possible embodiments of the first display parameter and the second display parameter are provided.
It is known that the first display parameter and the second display parameter correspond, i.e. when the first display parameter is a color coordinate, the second display parameter is also a color coordinate. Preferably, the first display parameter and the second display parameter may be brightness, and the brightness is acquired more conveniently and quickly.
It is understood that the first display parameter and the second display parameter may also include other parameters representing display effects, which may be set according to practical applications, and are not limited specifically herein.
In one embodiment, at S10: the step of acquiring at least one first display parameter in a first display area of the display screen and at least one second display parameter in a second display area of the display screen further comprises the following steps:
s01: the first display area is divided into at least one first display sub-area, and the second display area is divided into at least one second display sub-area.
Specifically, each first display sub-area corresponds to one first display parameter, and each second display sub-area corresponds to one second display parameter. Specifically, referring to fig. 4, fig. 4 is a schematic top view of a display screen according to another embodiment of the present invention. The display screen 100 is divided into a plurality of display sub-regions, that is, the first display region a is divided into at least one first display sub-region (a1, a2 … … a9), the second display region B is divided into at least one second display sub-region (B1, B2 … … B40), the area and the shape of each display sub-region may be the same or different, and may be specifically set according to an actual situation, in this embodiment, the area and the shape of the first display sub-region and the second display sub-region are the same.
In one embodiment, the second display parameter is the display parameter of the second display sub-area closest to the first display area 10. It will be appreciated that the extent of the second display region 20 is large and that the second display parameter is acquired from the region of the second display sub-region closest to the first display region 10. See in particular the second display sub-area located closest to the periphery (up, down, left, right) of the first display area 10 in fig. 4. It can be understood that the display effect of the second display sub-region closest to the first display region 10 should be close to the display effect of the first display region 10, further ensuring the accuracy of the evaluation method of the display screen.
In one embodiment, the length of the first display sub-region in the first direction (see the X direction in fig. 4) is 0.5 to 1.5mm, the length of the second display sub-region in the first direction (see the X direction in fig. 4) is 0.5 to 1.5mm, the length of the first display sub-region in the second direction (see the Y direction in fig. 4) is 0.5 to 1.5mm, and the length of the second display sub-region in the second direction (see the Y direction in fig. 4) is 0.5 to 1.5 mm. Preferably, the length of the first display sub-region in the first direction (see the X direction in fig. 4) is 1mm, the length of the second display sub-region in the first direction (see the X direction in fig. 4) is 1mm, the length of the first display sub-region in the second direction (see the Y direction in fig. 4) is 1mm, and the length of the second display sub-region in the second direction (see the Y direction in fig. 4) is 1 mm. By setting the lengths of the first and second display sub-regions in the first and second directions within this range, division of the display screen 100 into regions is facilitated.
