Abstract

The invention relates to a small-spacing LED display screen module based on an RGB split array, and belongs to the technical field of LED display screens. The light sources are R, G and B high-power single-color LED lamp beads, and light emitted by the light sources passes through the corresponding light valve arrays and then is projected to the rear panel. The light valve array can control the output intensity of a light path, and the light valve array is divided into three spatially independent areas corresponding to the three single-color LED lamp beads R, G and B respectively; each output pixel point on the front panel is connected with three sub-pixel points R, G and B on the rear panel by using an optical fiber bundle formed by three optical fibers to transmit light; the control panel is used for controlling the single-color LED lamp beads and the light valve array; and 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. High-power R, G and B LED single lamps are used, independent dimming can be achieved, and dynamic energy consumption is low. According to the invention, other additional accessories are not needed.

Description

technical field [0001] The invention relates to a micro-pitch LED display screen module based on an RGB split array, 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 achi...
