LED DISPLAY PANEL AND LED DISPLAY

WIPO Patent Application WO/2021/189777

A1

Provided are an LED display panel and an LED display. The display panel comprises a display back plate provided with an LED array. The LED array comprises LED chips arranged side by side. The LED chips comprise vertical emission type light-emitting chips and oblique emission type light-emitting chips. The vertical emission type light-emitting chips are arranged inside the LED array. The direction of chief rays emitted by the vertical emission type light-emitting chips is perpendicular to the direction of the display back plate. The oblique emission type light-emitting chips are arranged at an edge of the LED array. The direction of chief rays emitted by the oblique emission type light-emitting chips is away from the direction of the geometric center of the display back plate. The vertical emission type light-emitting chips are arranged inside the LED array, and the oblique emission type light-emitting chips are arranged at an edge of the LED array. By means of chief rays emitted by the oblique emission type light-emitting chips that are away from the direction of the geometric center of a display back plate, a light-gathering effect is formed between adjacent LED display panels, thereby preventing dark fringes from being generated between adjacent LED display panels, and improving the overall display effect.
