A light guide component of a screen soft keyboard character and a touch screen mobile phone

Abstract

Disclosed are a light guide assembly of screen soft keyboard characters and a touch screen cell phone. The light guide assembly is composed of a light shading film (510), a light guide film (520) and a light blocking film (530). The light shading film (510) is located on a front side of the light guide film (520), and hollowed holes (511) corresponding to the soft keyboard characters (421) are arranged on the light shading film (510). An upper half section of the light guide film (520) corresponds to the soft keyboard characters (421), and a lower half section corresponds to a LED lamp (210). The light blocking film (530) is located on an upper half section of a back side of the light guide film (520), so as to block light emitted by a LCD display screen (300) from entering the light guide film (520).

Description

Technical field [0001] The present invention relates to the field of touch screen mobile phones with soft keyboard characters arranged on the lower part of the screen surface, in particular to a light guide component and touch screen mobile phone with ultra-thin thickness, high display brightness, and screen soft keyboard characters that are not interfered by LCD display light sources . Background technique [0002] At present, the proportion of mobile phones using touch screens is getting higher and higher. The touch buttons at the bottom of the touch screen often need to have the effect of backlighting. The advantage of placing the LED light source directly under the soft keyboard characters on the touch screen cover is the brightness of the soft keyboard characters. The disadvantage is that the requirements for the puzzle are relatively high. In some positions, the light source cannot be directly placed directly below the soft keyboard characters. Each soft keyboard character ...

AI Technical Summary

Problems solved by technology

[0004] However, dislocation design of the LED light source and the soft keyboard characters on the touch screen cover will lead to uneven brightness displayed by the soft keyboard characters, and the problem that some areas cannot be lit; Part of the light on the LCD display screen interferes with the display of soft keyboard characters on the touch screen cover. When the soft keyboard characters are not lit, part of the light on the LCD screen will also affect the local position of the soft keyboard characters.

[0005] The traditional light guide medium includes injection molding a special light guide plate to guide the dislocated light path, but limited by the current injection molding conditions, the thickness of the injection molded light guide plate needs to be at least 0.4mm, which cannot meet the current ultra-thin development direction of mobile phones , and need to open the injection mold, the production cost is higher

[0006] Therefore, prior art still needs to improve and develop
