[0003] The reflector is one of the important components of the backlight panel. It is an optical film material matched with the light guide plate, which can effectively return the light source. However, since the dots of the light guide plate are inevitably in contact with the reflective coating of the reflector, there is some friction Chips, this kind of friction debris is hidden on the bottom plane of the light guide plate to form white spots, affecting the visual effect of the backlight panel, and even affecting the optical quality of the backlight panel

Abstract
The invention discloses an emission coating of an optical reflector plate and a preparation method. The emission coating comprises a base material and a reflection coating; the reflection coating is prepared from the following raw materials in percentage by mass: 60-70% of glycol diacrylate, 1-5% of trideoxyfluoride methacrylate, 5-10% of silicon dioxide sol, 1-5% of photoinitiator, 0.1-0.5% of calciumcarbonate, 0.1-0.5% of sulfuric acid, 0.1-0.5% of ethanol, 0.1-0.5% of ammonia water and the balance of deionized water. According to the emission coating and the preparation method disclosed bythe invention, the change of the emission coating structure reduces a gap between the coating structures, thus the density of the whole coating is higher, a friction effect between the emission surface coating and a light guide plate is weakened, and the influence on a luminous surface of the whole backlight panel is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of optoelectronic materials, in particular to an optical reflection sheet and a method for preparing an emission coating thereof. Background technique [0002] The so-called backlight panel is a light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. Liquid crystal itself does not emit light, it displays graphics or characters as a result of its modulation of light. With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Driven by the liquid crystal display market, the backlight industry is showing a scene of prosperity. The LCD is a non-luminescent display device, which needs a backlight source to achieve the display function. The performance of the backlight will not o...
