Background

At present, RGB indicating lamps of a mobile phone are generally placed below a touch screen at the top of the mobile phone, flashing display is used as visual prompt, and when unprocessed information and missed calls exist on the mobile phone, the RGB indicating lamps can flash and remind with different colors when the mobile phone is in a standby state, so that timely processing is facilitated. The LED display screen comprises an RGB indicator light, a silica gel sheet/light-diffusing film and a light hole of the touch screen. This kind of structure is higher to the assembly precision requirement, and the printing ink transmissivity of light trap printing can all influence the luminance and the display effect of pilot lamp just to the printing surface distance of printing opacity and RGB pilot lamp can not too far away.
