Problems solved by technology

[0004] 1. The diode spacing in the RGB pixel is too small, resulting in poor heat dissipation performance of the light-emitting diodes, which affects the overall display effect and device performance
[0005] 2. Due to the small spacing between the diodes in the RGB pixel, it is very easy to make the entire screen chromaticity uneven during the color imaging process, and the overall display resolution is relatively low, making the display effect unsatisfactory
[0006] 3. Since RGB only constitutes one imaging point, the requirement for high resolution can only be solved by increasing the number of RGB
[0007] 4. Due to the different types of diodes, the price varies greatly, and some even differ by more than ten times. While increasing the production cost, the display effect cannot be well guaranteed

Embodiment Construction

[0019] Such as Figure 7 The LED arrangement method of the three-lamp arrangement method of a class of three basic color LEDs shown is composed of RGB triangles.

[0020] The arrangement of RGB triangle individuals is: in the array of elements, the upper left is R (red light-emitting diode), the upper right is G (green light-emitting diode), and the bottom is B (blue light-emitting diode). The order of upper left, upper right, and lower is called an RGB triangle. image 3 That is a schematic diagram of the RGB triangle arrangement.

[0021] In this technology, behind the display screen is the electronic circuit control technology. Each monochromatic light point (R, B or G) on the display screen can be independently regarded as a point. Compared with the previous technology, it can ensure that the entire screen has better effects in terms of color, brightness and consistency.

[0022] Such as Figure 7 As shown, 1R1G1B in the figure constitutes a real pixel point, which is ...

Abstract

The invention belongs to the technology of LED display screen, and mainly relates to a three-lamp arrangement method of one type of three basic color LEDs. Its arrangement has the following characteristics: each LED is distributed uniformly and regularly, and the entire display screen is composed of RGB triangles as the basic unit arrangement. At the same time, on the display screen, three adjacent LEDs form an RGB triangle, which is the basic unit, and is evenly staggered and regularly spread out on the display screen. This arrangement solves the product cost difference caused by the quality of the LED material of the existing display screen, and at the same time better solves the problem of heat dissipation. On the premise of improving the display effect, the material cost is greatly reduced. An outdoor LED display application solution with advanced technology and worthy of promotion.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a method for arranging light-emitting diodes on the LED display screen. Background technique [0002] At present, the LED display screens widely used in the market generally have the arrangement of plug-in light-emitting diodes: three colors of plug-in light-emitting diodes RGB (R is a red light-emitting diode, B is a blue light-emitting diode, and G is a green light-emitting diode. Diodes) are tightly aggregated together, and the mutual distance is close to zero, as the basic unit of a light-emitting point, that is, a pixel, so as to achieve white balance. RGB pixels are used as the basic unit to evenly distribute on the display screen, so that the overall display purpose can be achieved. [0003] The diode arrangement of this kind of LED display has the following disadvantages: [0004] 1. The diode spacing in the RGB pixel is too small, resulting in poor heat dissipation performance ...
