Embodiment 1

[0030] Such as figure 1 shown.

[0031] A method for improving the display contrast of a display in a strong light environment, which is realized by dissolving a spectral absorption type material in the composite optical adhesive layer 3 that bonds the front panel glass 2 and the display 4, and the spectral absorption type material can be used according to the display color of the display , such as monochrome or color, and other special requirements, such as the requirements to eliminate near-infrared light and ultraviolet light, choose different materials from single-peak absorption to broad-spectrum absorption, or a mixture of multiple similar materials. The front panel glass 2 needs to be treated with an optical coating to reduce the reflectivity of the front surface of the glass. The coated glass can also have other functions, such as electromagnetic shielding, infrared removal, ultraviolet removal, etc. The display can be a display module, display component or display s...

Embodiment 2

[0034] Such as figure 2 shown.

[0035] The method of this embodiment is by coating a layer of spectral absorption type material on the side of the front panel glass opposite to the display ( figure 2 ) to achieve. All the other are the same as the first embodiment.

Embodiment 3

[0037] Such as image 3 shown.

[0038] The method of this embodiment is by coating a layer of spectral absorption type material layer on the surface of the display ( image 3 ) to achieve. All the other are the same as the first embodiment.

Abstract

The invention provides a method for improving display contrast of a displayer under strong light environment. The method for improving the display contrast of the displayer under the strong light environment is characterized in that the method includes the steps that (1) spectrum absorption type materials are dissolved in composite optical glue for bonding front panel glass and the displayer; (2) the face, opposite to the displayer, of the front panel glass is coated with a spectrum absorption type material layer; (3) the surface of the displayer is coated with a spectrum absorption type material layer; (4) a spectrum absorption type material layer is added in the transparent composite optical glue for bonding the front panel glass and the displayer. According to the method, the strong ambient light contrast ratio of the displayer can be effectively improved, and meanwhile display color saturation and color gamut indexes of the displayer can be improved.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a technology for overcoming the influence of external strong light on the display quality, in particular to a method for improving the display contrast under the strong light environment of the display. Background technique [0002] At present, displays have been used in various media, games, multimedia teaching, aircraft, engineering vehicle operation control, etc. Since the front screen of the display has a reflective layer or device structure that can reflect ambient light, there is strong reflected light on the surface of the front screen of the display under strong light conditions (such as outdoor sunlight), resulting in white, blurred, and blurred displays. The contrast ratio drops, seriously affecting the reading and recognition of normal display content. At present, there are many patented methods to reduce the influence of ambient light and improve the contrast ra...
