Abstract

The invention relates to a small-spacing LED display screen module based on high-power LEDs, and belongs to the technical field of LED display screens. Comprising a light valve array, a rear panel and a front panel, wherein the light valve array consists of a high-power white light LED lamp bead and a light valve with an optical filter; a lampshade for uniformly gathering light to the input surface of the light valve array is arranged between the light source and the light valve array; each light valve comprises three sub light valves which are respectively provided with a red color filter, a green color filter and a blue color filter to form three sub light paths which respectively pass through the red color filter, the green color filter and the blue color filter, and the sub light valves can control the output intensity of the sub light paths; the rear panel and the front panel are connected through an optical fiber for guiding light; and the control panel is used for controlling the LED and the light valve array. The high-power white-light LEDs are used for replacing a large number of low-power LEDs to serve as the light source of the display screen, the use amount of the LED lamp beads and the drive circuit can be greatly reduced, the manufacturing scale is reduced, and the production efficiency is improved. As the number of the light sources is greatly reduced, the fault probability of the display screen is remarkably reduced, and the average fault-free time and the reliability are improved.

Description

technical field [0001] The invention relates to a micro-pitch LED display screen module based on high-power LEDs, and belongs to the technical field of LED display screens. Background technique [0002] The current display technologies mainly include LED screens, OLED screens, LCD screens, and projection screens (DLP, LCD, etc.). [0003] The projection screen (or projection splicing screen) needs to project light on a white background, with low brightness and poor contrast, suitable for darker environments. [0004] LCD screens have high brightness, black background, and high contrast. However, as the size of a single screen increases, the manufacturing cost per unit area rises sharply, and it is only suitable for small and medium screens. However, LCD screens are spliced ​​into large screens. Because LCD screens use glass as the carrier and TFT manufacturing process, the display area must be smaller than the glass carrier, and the necessary structural frame cannot achieve...
