Panel, method for forming concealed light hole of panel and touch screen with panel

Abstract

The invention discloses a panel, a method for forming a concealed light hole of the panel and a touch screen with the panel. The panel comprises a transparent substrate, a main body black ink layer, a cover bottom black ink layer, an IR (iridium) light-transmitting ink layer and a semi-transparent ink layer, wherein the transparent substrate is provided with a first surface and a second surface; the second surface is opposite to the first surface; the first surface is a window surface; the main body black ink layer is arranged at the edge of the second surface; an area, which surrounds the second surface, of the main body black ink layer is a window area; a through hole is formed in the main body black ink layer; the cover bottom black ink layer covers the main body black ink layer; the through hole is exposed out of the cover bottom black ink layer; the IR light-transmitting ink layer covers the area of the through hole; the semi-transparent ink layer covers the IR light-transmitting ink layer, and completely covers the through hole, so that the concealed light hole is formed. The panel is provided with the concealed light hole; and transmission light is uniform and soft.

Description

【Technical field】 [0001] The invention relates to the field of display screens, in particular to a panel, a method for manufacturing the hidden light-transmitting holes thereof, and a touch screen using the panel. 【Background technique】 [0002] In the touch screen industry, for example, in the touch screen design with a black frame, if there is an indicator hole, it is almost required to be a hidden light transmission hole, that is, the light can be transmitted when the light is on, and the color when the light is off is the same as the color of the black frame of the touch screen. unanimous. At present, it is realized in the industry by screen printing black or purple blue IR light-transmitting inks that are similar to the main black inks, and the transmittance is generally controlled at 4% to 30%. Because the light source of many indicator lights is very strong and the penetrating power is very strong, although the transmittance of the screen printing hole has reached 4%...

AI Technical Summary

Problems solved by technology

Because the light source of many indicator lights is very strong and the penetrating power is very strong, although the transmittance of the screen printing hole has reached 4%, the light passing through is still very dazzling, or light leaks, especially when sleeping at night. The light of the indicator light can illuminate the ceiling of the room, seriously affecting the normal work and rest of users, and users have great opinions, which has always troubled mobile phone design manufacturers
