Description

Technical Field

[0001] The utility model relates to the technical field of display modules and backlights, and in particular to an LCD display screen. Background Art

[0002] LCD display, the white light emitted by the backlight is converted into three-color light through the pixels of the TFT liquid crystal display, and then forms a display image. The backlight light comes from a row of backlight LED lamps at the bottom of the backlight. The light emitted by the LED lamps is scattered and guided by the backlight film material to form a surface light source, and then emits the light to the TFT liquid crystal screen. The backlight shading glue is a "frame" shaped glue, which covers the edges that are not displayed, and does not block the area in the middle that is to be displayed and emit light. Since the bottom is where the backlight LED light bar is, the brightness is relatively high, it is easy to form a white edge or a white brightness edge effect in visual effect (human eye effect).
