Abstract

The invention relates to a light dispersion preventer for LCD of a mobile telephone, comprises a main light-guiding body to install the LCD, which has a first side and a second one; an extension part extending from the first side and having a surface and a gap, where the gap is used to hold a light source; a first reflecting layer arranged on the surface; and a second reflecting layer arranged on the second side; where the light source is reflected by the two reflecting layers to enhance the gray scale of the LCD.

Description

technical field [0001] The invention relates to an anti-scattering device of a liquid crystal display, in particular to an anti-scattering device of a liquid crystal display of a mobile phone with a reflective layer. Background technique [0002] Due to the popularity of handheld electronic devices such as mobile phones, personal digital assistants, smart phones, and stock machines, the diversification and demand for liquid crystal displays (LCDs) in the market continue to increase. [0003] However, the LCD panel itself does not have luminous properties. Therefore, a light source must be added to the LCD panel to achieve the display effect, that is, an optical component of a backlight is required to provide the light source of the LCD panel. The optical component of the backlight is mainly composed of a light source, a light guiding and diffusing member, and an optical diaphragm. After the light source emits light, it enters into the light guiding and diffusing member. The...
