Abstract

The invention discloses a LCD display, including an LCD panel and a backlight module. The backlight module is used for the lights of the LCD panel. The backlight module includes a illuminator with a smooth entry, an illumination installed at the entry point to the smooth side and a light installed at the point light source with the luminous zone between the Illuminator-regulation enclosures the cover-regulation in relation to the side of the illumination at least one cavity formation. The LCD light output is of high brightness uniformity.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display. 【Background technique】 [0002] Due to the advantages of thinness, lightness, low power consumption, and no radiation, liquid crystal displays are widely used in electronic equipment such as notebook computers, mobile phones, digital cameras, and instrumentation for display terminals. However, since the liquid crystal layer itself cannot emit light, in order to achieve the display effect, a backlight module structure is usually used to provide the required light source. At present, in large-size liquid crystal displays, most of the light sources use cold cathode ray tubes, but because cold cathode ray tubes contain mercury (Hg), a substance harmful to human body, which does not meet the environmental protection requirements of products, it has been used by most The state expressly prohibits its use. [0003] At present, in large-size liquid crystal displays, the backlight module often adopts a dire...
