Abstract

The present invention relates to the field of LED technology, in particular to an LED line backlight liquid crystal display, comprising a liquid crystal glass and a light guide plate, the light guide plate is arranged on one side of the liquid crystal glass, and the end face of the first end and the end face of the second end of the light guide plate are both The LED line backlight is provided. The LED line backlight includes a strip-shaped circuit substrate. At least one row of light-emitting components is arranged on the side of the circuit substrate close to the light guide plate. Each row of light-emitting components includes a number of RGB light-emitting components arranged at intervals along the length of the circuit substrate. unit. Liquid crystal glass, light guide plate and LED line backlight form a transparent liquid crystal display structure. Multiple RGB light-emitting units are arranged linearly on the circuit substrate. The three-color LED chips of the RGB light-emitting unit can be arranged in high density, while the RGB light-emitting unit The unique three-color LED chips can be independently controlled, and the LED line backlight can be adjusted as needed to meet the requirements of transparent LCD screens for color gamut and high brightness.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED line backlight liquid crystal display. Background technique [0002] The backlight of the existing liquid crystal display screen (LCD screen) basically adopts phosphor powder white light LED lamp beads to provide the backlight source. With the development of technology, it is found that the phosphor white LED lamp beads have the following defects: 1. The color of the phosphor white LED lamp beads is fixed and cannot be adjusted; 2. The color gamut of the phosphor white LED lamp beads is not wide enough. Therefore, the backlight source of the current LCD screen cannot meet the requirements of the small-sized display screen on the color gamut and brightness of the screen. Contents of the invention [0003] An embodiment of the present invention provides an LED line backlight liquid crystal display to solve the above technical problems. [0004] An LED line backlight liquid ...
