This flexible shielding piece 4 can be extruded by sensor holder 13 and display screen 1 and produce elastic deformation to be full of the clearance between sensor holder 13 and the display screen 1, thereby guarantee that external ambient light can not cross flexible shielding piece 4 and produce the influence to the measuring result of light sensor 3.

The working principle is as follows:
as shown in fig. 10-11, the display device is in a normal use state without any obstruction in the front of the display screen 1, while the light sensor device is in a completely hidden state (refer to fig. 11-11a position) when the display device is viewed from the front. When the display device needs to correct the brightness and chromaticity of the display screen 1, firstly, the first driving unit 8 is extended, so that the right-angle connecting piece 10, the second driving unit 9, the flat plate 11, the third driving unit and the sensor unit 2 are linearly displaced upwards and exceed the height of the upper side surface of the display screen 1 (refer to the positions of fig. 11-11 b); then the second driving unit 9 is extended, so that the flat plate 11, the third driving unit and the sensor unit 2 are linearly displaced towards the front direction of the display screen 1 and exceed the front position of the display screen 1 (refer to the positions of fig. 11-11 c); then the first driving unit 8 is contracted, so that the right-angle connector 10, the second driving unit 9, the flat plate 11, the third driving unit and the sensor unit 2 are linearly displaced downwards until the sensor unit 2 is level with the height of a display area in front of the display screen 1, which is required to measure the luminance and chromaticity (refer to the positions of fig. 11-11 d); the third driving unit is then extended so that the sensor holder 13 approaches the display screen 1 until the ring-shaped foam 4 is squeezed and deformed by the sensor holder 13 and the display screen 1, thereby filling up possible gaps around the light sensor 3 and isolating the interference of external light to the measurement process (refer to fig. 11-11 e). At this time, the optical sensor 3 starts to operate to measure parameters such as luminance and chromaticity of the display screen 1, and after the measurement operation is completed. The first driving unit 8, the second driving unit 9 and the third driving unit sequentially move reversely in reverse order according to the above flow until the original position (refer to the position of fig. 11-11 a) is restored, and the display device can be continuously and normally used.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
