Problems solved by technology

[0003] Filtering out blue light and protecting eyes in the liquid crystal display industry is one of the urgent issues to be solved in the display industry. At present, the methods used in the market are mainly anti-blue light protective stickers, wearing anti-blue light glasses, or processing blue light devices. These methods It will lead to some other problems, such as reducing the brightness of the display screen and the sensitivity of screen capture, inconvenient use, color difference, etc.

Embodiment 1

[0022] A color filter is provided in this embodiment, such as figure 1 As shown, it includes components sequentially formed on a glass substrate 1 : a black matrix 2 , a color layer 3 , a protective layer 4 , an electrode layer 5 , a first alignment film 7 and a gap layer 6 . Wherein, the protection layer 4 , the electrode layer 5 , and the first alignment film 7 are sequentially formed on the surface of the color layer 3 ; a gap layer 6 is also formed on the surface of the electrode layer 5 . Among the components: black matrix 2, color layer 3, protective layer 4, first alignment film 7 and gap layer 6, at least one component contains a blue light absorber, and the blue light absorber accounts for the total amount of raw materials for the component. 1 to 10% of the mass. Of course, the structure of the color filter is not limited to the structure of this embodiment.

[0023] The present embodiment also adopts the above-mentioned color filter assembly to form a liquid crysta...

Embodiment 2

[0039] In this embodiment, the blue light absorber is added during the raw material manufacturing process of each component. Since the raw material formation process of each component is carried out in the photoresist production plant.

[0040] Taking the manufacturing process of BM raw materials as an example, it generally has the following steps:

[0041] Step 1, the reaction raw materials such as pigments and their dispersions, high polymers, photosensitizers, etc. are mixed, stirred and reacted for a period of time to obtain photoresist materials for preparing BM, that is, raw materials for BM preparation;

[0042] Step 2, adding a blue light absorber, such as Ouwende 47, during the above step 1, the dosage of which is 1-10% of the total mass of the reaction raw materials.

[0043] Step 3, the BM preparation raw material with the blue light absorber added, after filtering and filling processes, can be packaged and shipped or transported to the liquid crystal display produ...

Abstract

The invention relates to the technical field of liquid crystal display, in particular to a color filter. The color filter comprises components including a black matrix, color layers, a protection layer and a gap layer. At least one component contains blue light absorbent which accounts for 1% to 10% of the total mass of preparation raw materials of the components where the blue light absorbent is located. The invention further provides a preparation method of the color filter. The blue light absorbent is added to the components of the color filter, blue light which greatly harms eyes of people is completely or partly absorbed effectively, and the risk of vision damage is lowered.

Description

technical field [0001] The invention relates to the field of liquid crystal technology, in particular to a liquid crystal display with eye protection function. Background technique [0002] Medical research shows that the photosensitive wavelength of the human eye is above 390nm and below 760nm. Among the visible light emitted by the display screen, blue light has the shortest wavelength and the strongest energy. As the visible light with the strongest energy, blue light includes blue, indigo, and violet light. They penetrate the cornea and lens directly into the macula, accelerating the oxidation of macular cells. , damage the retinal photoreceptor cells and damage the vision of the human eye. [0003] Filtering out blue light and protecting eyes in the liquid crystal display industry is one of the urgent issues to be solved in the display industry. At present, the methods used in the market are mainly anti-blue light protective stickers, wearing anti-blue light glasses, o...
