- the anti-glare coating on the surface of the glass substrate After spraying the anti-glare coating on the surface of the glass substrate, some coating particles will be distributed on the glass substrate to form a certain roughness on the surface of the glass substrate.
- the distribution of particles formed on the glass substrate by spraying anti-glare coating or chemical etching is relatively random and the size is relatively large.
- the resolution of the display screen is getting higher and higher, for example, the current display screen resolution has reached 4K or even 8K
- the particle distribution on this surface is relatively random and the size is relatively small.
- a flash point phenomenon will occur, which will seriously affect the visual effect of the screen.
- the reason for the flash point is that when the light emitted by the display screen passes through the surface of the anti-glare glass cover, it will be refracted by the particles distributed on the surface of the anti-glare glass cover, thereby generating light focusing and forming a flash point phenomenon.
- the principle of the generation of the flash point phenomenon will be explained in detail below with reference to FIG. 2 .
- FIG. 2 it is a schematic diagram of the light from the display screen reaching the human eye through the glass cover when the surface of the glass cover on the display screen is smooth, that is, there are no particles.
- the picture displayed on the display screen can be regarded as composed of a large number of pixels.
- an image with a resolution of 1920 ⁇ 1080 can be regarded as including 1920 pixels in each row and 1080 pixels in each column.
- Each pixel is called a pixel unit of the display screen, and each pixel unit includes three sub-pixels with the same size, namely R sub-pixel, G-series pixel, and B sub-pixel.
- the three sub-pixels display red, green, and blue respectively. Three colors of light.
- the particles formed on the glass cover plate are unevenly distributed and larger in size, far larger than the size of the sub-pixels of each pixel unit of the display screen, as shown in (d) in Figure 2 , resulting in a large difference in the distribution of particles on the surface of the glass cover plate corresponding to the sub-pixels of each pixel unit, and the amount of light generated by the sub-pixels of each pixel unit passing through the glass cover plate also has a large difference.
- the light is very uneven, resulting in severe flash points.
- the applicant has deeply studied the influence of the particle size on the glass cover plate of the display screen on the flash point phenomenon. After extensive experiments, the applicant found that if the distribution of particles on the glass cover of the display screen is not uniform, or if the average width (RSM) of the particles is larger than the size of the sub-pixels of the pixel unit of the display screen, the sub-pixels of each pixel unit will be The distribution of the particles on the surface of the glass cover plate corresponding to the pixels is quite different, resulting in different light transmission amounts of the light generated by different sub-pixels passing through the glass cover plate, and light of different colors (for example, R, G, B) passing through the glass The light transmittance of the cover is different, and the flash point phenomenon is more serious.
- RSM average width
- the distribution of particles on the surface of the glass cover corresponding to each pixel unit is basically Consistent (that is, the corresponding concave and flat parts are the same), so that the light transmittances of different colors of light generated by different pixel units passing through the glass cover are the same, and the phenomenon of flash point can be avoided.
- the particles can be evenly distributed on the glass cover, and the width of the particles is basically the same.
- the particles are on the glass cover.
- the uniformity of the distribution on the plate will be limited to a certain extent, and the shape and structure of the particles themselves may not be completely consistent, and there will be some differences.
- the difference of the particles distributed on the surface of the glass cover plate corresponding to each pixel unit is also smaller, and it is less likely to appear. flash point phenomenon.
- the applicant has found through a large number of experiments that in actual use, when the RSM of the particles on the anti-glare layer is less than or equal to half the size of the sub-pixels of the pixel unit of the display screen, the distribution of the surface of the glass cover corresponding to each sub-pixel is Even if there is a difference in the particles, the difference is relatively small, which can basically avoid the flash point problem and greatly improve the display effect.

Une plaque de couverture en verre (51) d'un écran d'affichage (50), et son procédé de préparation. Une couche (511) antireflet est générée sur un substrat en verre par réalisation d'un traitement de givrage sur le substrat en verre, de manière à préparer une plaque de couverture en verre (51) antireflet. Pendant le traitement de givrage, de la poudre de givrage peut être pulvérisée uniformément sur le substrat en verre par un dispositif de pulvérisation, puis une liqueur acide est pulvérisée par le dispositif de pulvérisation sur le substrat en verre recouvert de la poudre de givrage uniformément répartie, de façon à former des particules réparties de manière uniforme (5111) sur le substrat en verre, et de façon à obtenir la couche (511) antireflet, le diamètre de pore d'une buse de pulvérisation du dispositif de pulvérisation pouvant être déterminé en fonction de la taille de sous-pixels d'une unité de pixel de l'écran d'affichage (50), de manière à réguler la taille des particules (5111) formées dans la couche (511) antireflet pour qu'elle soit inférieure ou égale à la moitié de la taille des sous-pixels de l'unité de pixel de l'écran d'affichage (50), de telle sorte que la plaque de couverture en verre (51) préparée peut assurer une fonction antireflet et peut également empêcher un phénomène de papillotement.
