Abstract
Disclosed is an LED display screen module comprising es a module substrate and a plurality of LED package structures. The LED package structures are disposed on the module substrate and arranged into an array. Each of the LED package structures includes a plurality of pixels and a packaging layer. The pixels are spaced apart from each other. The packaging layer includes a plurality of packaging portions and a plurality of connecting portions. The packaging portions respectively cover the pixels, and each of the connecting portions is connected between the adjacent two packaging portions. Each of the packaging portions has an upper light emitting surface and a lateral light emitting surface.The upper light emitting surface is a flat surface and is connected to the lateral light emitting surface via a transitional curved surface. Thereby, the color consistency and brightness uniformity of the LED display module can be improved.
Description
technical field [0001] The invention relates to a display screen module, in particular to a multi-pixel LED display screen module. Background technique [0002] Light-emitting diodes (Light-Emitting Diodes, LEDs) have the advantages of small size, high luminous efficiency, low energy consumption, etc., and can emit different colors of light, so they have a good application prospect in display screens. In order to have a better display effect, the existing LED display screen will use red, green and blue three-color light-emitting diode chips in a single package pixel; however, as the resolution of the LED display screen becomes higher and higher, the packaging body The volume of the LED needs to be made smaller and smaller accordingly, so that multiple pixels are closer to each other, and the external electrodes of the red, green, and blue light-emitting diode chips are becoming more and more dense, which leads to the complexity of the circuit design and the overall The prod...
