Nationstar Optoelectronics obtains patents for LED display devices and LED display panels

According to news from the financial industry on June 14, 2024, Tianyancha Intellectual Property Information shows that Foshan Guoxing Optoelectronics Co., Ltd. has obtained a project called "an LED display device and LED display panel", with the authorization announcement number CN221150014U, and the application date is November 2023.

The patent abstract shows that the present utility model discloses an LED display device and an LED display panel. The LED display device includes a circuit substrate and an LED light-emitting chip; the circuit substrate includes a first surface and a second surface, and the first surface and the second surface are arranged oppositely. A solid crystal pad is provided, and the LED light-emitting chip is arranged on the solid crystal pad in a formal structure; the first surface is also provided with an outer wire bonding pad and an inner wire bonding pad, the electrical properties of the outer wire bonding pad and the solid crystal pad are the same, and the electrical properties of the inner wire bonding pad and the solid crystal pad are different. The utility model adopts an LED light-emitting chip with a formal structure, and sets the solid crystal pads to have the same electrical properties as the outer wire bonding pads, so that the distance between the die solid pads and the outer wire bonding pads is smaller, effectively reducing the size of the device, achieving smaller dot spacing, ensuring the performance and safety of the device, while reducing production costs and improving device integration.
