Embodiment Construction

[0019] It has been mentioned in the background technology that since the pixel module of the existing LED display is integrated and packaged by many pixel units, there is inevitably a large gap between the pixel units, which affects the pixel density and The clarity has a great impact, hindering the development of LED display screens to the field of high-definition display. Therefore, the present invention provides an LED display screen and a manufacturing method thereof. The pixel module of the LED display screen is a single LED chip, so that the gap between each pixel can be effectively controlled, thereby improving the LED display. screen clarity. Moreover, each pixel is separated by an isolation channel, which avoids mutual influence between pixels during work, and further improves the clarity of the LED display.

[0020] The present invention will be described in more detail below with reference to the accompanying drawings, wherein preferred embodiments of the present i...

Abstract

The invention discloses a structure of an LED (light-emitting diode) display screen and a manufacturing method thereof. The pixel module of the LED display screen is a single LED chip. The LED chip comprises a substrate, a chip which is formed on the substrate, P electrode groups and N electrode groups, wherein the chip is divided into pixel units through isolating channels, the P electrode groups are distributed in the center of each pixel unit and the N electrode groups are distributed at the four corners of each pixel unit. By using the LED display screen provided by the invention, gaps among pixels can be effectively controlled and the definition of the LED display screen is improved. Moreover, the pixels are isolated by isolating channels, the situation that the pixels influence each other during working is avoided and the definition of the LED display screen is further improved.

Description

technical field [0001] The invention relates to the technical field of LED manufacturing, in particular to an LED display screen and a manufacturing method thereof. Background technique [0002] With the increasing development of LED technology, LED devices play an increasingly important role in various fields due to their advantages of energy saving, environmental protection and long life. Among them, the manufacturing process in the field of LED display is also becoming more and more mature, from the initial single-color display composed of LED bead arrays to colorful and full-color displays composed of LED chip matrix blocks, LED display It has been widely used in multimedia advertising and public notice display. [0003] Since the LED display screen is usually integrated and packaged by multiple individually packaged LED chips, due to the limitations of its own structure and packaging process, there is inevitably a large gap between the LED chips, which affects the pixe...
