Problems solved by technology

[0003] In order to overcome the problems of poor color mixing and color cast when viewed from a large viewing angle in the prior art, the present invention combines LED light-emitting tubes of three primary colors to form a cylindrical pixel module, and its top light-emitting surface is flat, convex, concave or The uneven light-emitting surface makes the color mixing effect of the display soft and uniform, suitable for viewing from a large viewing angle. The purpose is to provide a three-color LED pixel module

Embodiment Construction

[0022] Embodiments 1 to 15 of the present invention are composed of columnar LED light-emitting tubes with three primary colors of red, green and blue with a cylindrical convex surface on the outside and two planes on the inside.

[0023] Red, green, and blue three-primary color cylindrical LED light-emitting tubes can be inverted between the outer cylindrical convex surface and the inner plane or curved surface, between the outer cylindrical convex surface and the top light-emitting surface, and between the inner plane (or curved surface) and the top light-emitting surface. corner transitions, such as Figure 1-13 shown. The top light-emitting surface of the cylindrical pixel module composed of three primary color LED light-emitting tubes can be flat (such as figure 1 , 2 , 3, 4), spherical concave (such as Figure 5 , 6 , 7, 8), spherical convex surface (such as Figure 9 , 10 , 11, 12), conical concave surface, conical convex surface, polygonal pyramid concave surface...

Abstract

A new tricolor LED (light-emitting diode) pixel module in the LED luminotron display screen technology field, it is: the pixel module consists of column LED luminotron that is the tricolor namely red, green and blue, and the outer side is column convexity and the inside is 1-10 planes or curved surfaces; the tricolor LED luminotron assembleds together and forms the column pixel module; the top luminous surface of the column pixel module is the plane luminous surface, the globose concave, the globose convexity, the conical concave, the conical convexity, the multi-pyramiding concave with 3 to 15 ridges, the multi-pyramiding convexity with 3 to 15 ridges, the globose convexity with opening shuttle groove or the accidented luminotron surface. The invention can solve the chromatic polarization question.

Description

technical field [0001] The invention belongs to the technical field of LED display screens, and relates to an LED light-emitting tube pixel module, in particular to a three-primary-color LED pixel module. Background technique [0002] At present, in commonly used three-primary-color LED pixel modules, the single-color LED light-emitting tubes in the pixel group are cylindrical, and the light-emitting surface is flat or spherical. The LED light-emitting tubes of the three primary colors are scattered and arranged in an equilateral triangle or a right angle, and the shape of the pixel group is a triangle or a square. Since the LED light-emitting tubes of the three primary colors are arranged in a dispersed manner, no matter the triangular or square pixel group, there is a problem of poor color mixing. When the position of the display screen is high, the viewing effect can only be good at a distance from the display screen. When viewing at a close distance, due to the increase...
