In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the following description of the present invention will refer to the accompanying drawings and illustrate embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3, the utility model provides a pair of high screen accounts for than sensitization structure, it includes from last to lower laminated first antireflection layer 100 in proper order, apron 200, second antireflection layer 300, display screen 400, glass substrate 500, backlight 600 and light sense module 700, the middle part of backlight 600 sets up through-hole 610, light sense module 700 inlays to be established through-hole 610 department, light sense module 700 is connected with terminal cpu electricity.

Specifically, the first anti-reflection layer 100, the cover plate 200, the second anti-reflection layer 300 and the display screen 400 are sequentially stacked and fixed together by gluing, the cover plate 200 is transparent and protects the display screen 400, the display screen 400 and the glass substrate 500 are fixed and electrically connected by gluing, the glass substrate 500 and the backlight plate 600 are fixed by gluing, a through hole 610 is formed in the middle of the backlight plate 600, the middle of the through hole is not limited to be the middle, the light sensing module 700 is clamped in the through hole 610, the light sensing module 700 is electrically connected with the terminal cpu and is controlled by the terminal cpu, for example, when the terminal cpu is in a standby state, the terminal cpu does not process light change at the moment, namely, the signal of the light sensing module 700 is received and an instruction is not sent to the display screen 400. When the bright screen is unlocked, the light sensing module 700 reads and calculates the ambient light passing through the screen in real time, the brightness value of the ambient light corresponding to the wavelength is converted into an electric signal through the photoelectric sensor in the light sensing module, the result is fed back to the terminal cpu, and the terminal cpu sends an instruction to the brightness controller of the display screen 400 to adjust the brightness of the display screen 400 according to the information fed back by the light sensing module 700. Meanwhile, light emitted by the display screen 400 is refracted and absorbed by the second anti-reflection layer 300 and the first anti-reflection layer 100 and reflected by the backlight plate 600, the light basically does not irradiate the light sensing module 700 below the display screen 400, filtering can be realized by an algorithm for individually interfering stray light, the intensity and wavelength of partial stray light reflected and refracted by the screen cannot reach the threshold value set by the photoelectric sensor and is filtered, and the area of partial stray light cannot reach the threshold value of the algorithm due to the angle of the incident light to the photoelectric sensor and is also filtered, so that the effect that the light sensing module 700 is not interfered by a bright screen is achieved.

In some embodiments, the light sensing module 700 is an optical fingerprint module, which is compatible with the function of the light sensor, thereby saving the cost.
