Problems solved by technology

The display module includes a display panel and a support plate. The display panel includes one or more marks; The light-transmitting part is used to block the light of the display panel from passing through, and the orthographic projection of the light-transmitting part on the display panel covers at least part of the mark. However, the display module has the effect of diffusing light and protecting eyes. Not very good

Embodiment 1

[0028] In an eye protection display module provided by the present invention, the glass substrate 3 includes an upper polarizer 32, a glass flow sheet 33 and a lower polarizer 34 connected in sequence, and the backlight module 4 includes an upper brightness enhancement sheet 41, a lower brightness enhancement Sheet 42, light guide plate 43.

[0029] It should be noted that the lower polarizer 34 is a blue light filter, and the filter rate of the blue light filter is 25%-35%.

[0030] As a preference, the light source of the backlight module 4 is LED, the glass substrate 3 is PET, the first adhesive layer 31 and the second adhesive layer 35 are OCA adhesive layers, and the light source passes through the light guide plate 43 to conduct more than 90% of the light source. Then the light is enhanced by the upper brightness enhancement sheet 41 and the lower brightness enhancement sheet 42, and then the light source reaches the lower polarizer 34 of the glass substrate 3, that is, ...

Embodiment 2

[0032] In an eye protection display module provided by the present invention, the glass substrate 3 includes an upper polarizer 32, a glass flow sheet 33 and a lower polarizer 34 connected in sequence, and the backlight module 4 includes an upper brightness enhancement sheet 41, a lower brightness enhancement Sheet 42, light guide plate 43, lower polarizer 34 is a blue light filter, and the filter rate of blue light filter is 25%-35%, what lower polarizer 34 selects for use is a haze sheet, without light sheet.

[0033] As a preference, the light source of the backlight module 4 is LED, the glass substrate 3 is PET, the first adhesive layer 31 and the second adhesive layer 35 are OCR adhesive layers, and the light source passes through the light guide plate 43 to conduct more than 90% of the light source. Then the light is enhanced by the upper brightness enhancement sheet 41 and the lower brightness enhancement sheet 42, and then the light source reaches the lower polarizer 34...

Abstract

The invention discloses an eye protection display module which comprises a touch panel, a glass substrate and a backlight module which are connected in sequence, wherein the glass substrate comprises an upper polaroid, a glass flow sheet and a lower polaroid which are connected in sequence, the backlight module comprises an upper brightness enhancement sheet, a lower brightness enhancement sheet and a light guide plate, the lower polaroid is a blue light filtering sheet, and the light filtering rate of the blue light filtering sheet is 25%-35%. When the eye protection display module is applied to electronic equipment, the function of protecting eyes can be achieved, the reflectance to the eyes is reduced, the light transmittance of the eye protection display module is not affected, the effect of filtering the blue light can be achieved, and irreversible damage of the blue light to eyeballs is effectively prevented.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an eye protection display module. Background technique [0002] Liquid crystal display has gradually become the mainstream in the development of various display devices due to its lightness, lightness, energy saving, environmental protection and other characteristics. In today's society, people rely more and more on electronic devices. They spend a lot of time interacting with display devices such as mobile phones, computers, and TVs every day. Human eyes are also deeply poisoned by the blue light from these electronic display screens. In order to reduce the damage of blue light to human eyes, various anti-blue light films or glasses have appeared on the market. The anti-blue light effect can be achieved by preparing the anti-blue light film layer on a flexible substrate or glass to make an anti-blue light film or anti-blue light glass, and then pasting it on the surface of...
