[0019] The technical solution of the present utility model is further described below with reference to specific embodiments.

[0020] The present invention relates to a visual optimization system based on a display screen, see the attached Figure 1 , including glass surface layer, shielding grid layer, touch screen layer and LCM.

[0021] The glass surface layer is made of 0.35mm thick lightweight and high-strength composite glass. The upper surface of the glass surface layer is coated with an optical vacuum coating of Nb2O5 and SiO2 composite material to convert mirror reflection into diffuse reflection and allow as much light as possible to pass through the screen glass or be absorbed by the glass, so as to greatly reduce the interference of reflected light entering the eyes on the line of sight, improve the display effect of the screen, and increase visibility in sunlight.

[0022] The lower surface of the glass surface layer is bonded to the TOP ITO FILM layer of the touch screen layer via a 0.1 mm thick optical OCA. The touch screen layer includes a TOP ITO FILM layer and a BOTTOM ITO FILM layer. The TOP ITO FILM layer and the BOTTOM ITO FILM layer are bonded via a 0.1 mm thick optical OCA.

[0023] The shielding mesh layer is placed between the lower surface of the glass surface layer and the TOP ITO FILM layer of the touch screen layer. The shielding mesh layer is 0.15mm thick, the base material is PET, and the shielding mesh aperture is 0.18mm. The shielding mesh layer can effectively block electromagnetic interference from the external environment on the display screen.

[0024] The LCM is bonded to the BOTTOM ITO FILM layer of the touch screen layer through a 0.1mm thick optical OCA. LCM (LCD Module) is a liquid crystal display module, which refers to a component that assembles a liquid crystal display, a control and driving circuit unit, and a backlight source.

[0025] Furthermore, the control and drive circuit unit of the LCM is also connected to a light sensor. Figure 2 The light sensor model is EM30719, and the 1 and 7 pins of EM30719 are connected to the control and drive circuit unit of LCM through I2C communication.

[0026] The light sensor EM30719 is used to sense the ambient light intensity of the touch screen in real time, and convert the light intensity into an electrical signal and send it to the control and drive circuit unit of the LCM. The control and drive circuit unit of the LCM automatically adjusts the display brightness of the LCD screen based on the light intensity detection data of the light sensor. It can also automatically adapt to adjust the color temperature, hue, contrast and other parameters of the LCD screen, thereby reducing eye stimulation and further improving the user's visual comfort under different ambient light conditions.

[0027] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
