Problems solved by technology

Due to the limited structure, LED chips cannot be placed on the edge of the LED display panel, but a certain blank area is left. When two adjacent LED display panels are spliced ​​together, this blank area will cause the adjacent LED display panel to display There will be visually dark lines between the panels, which will affect the overall display effect

Abstract

The invention provides an LED display panel and an LED display, the LED display panel comprises a display backboard provided with an LED array, and the LED array comprises LED chips arranged side by side; the LED chips comprise vertical emitting type light-emitting chips and inclined emitting type light-emitting chips. The vertical emitting type light-emitting chip is arranged in the LED array, and the orientation of main light emitted by the vertical emitting type light-emitting chip is perpendicular to the direction of the display backboard; the inclined emitting type light-emitting chip isarranged in the edge of the LED array , and main light emitted by the inclined emitting type light-emitting chip faces the direction far away from the geometric center of the display backboard. The vertical emitting type light-emitting chip is arranged in the LED array; the inclined emergent light-emitting chip is arranged in the edge of the LED array, the main light rays which are emitted by theinclined emitting type light-emitting chips and face the direction far away from the geometric center of the display back plate form a light condensation effect between the adjacent LED display panels, so that dark fringes are prevented from being generated between the adjacent LED display panels, and the overall display effect is improved.

Description

technical field [0001] The invention relates to the technical field of light-emitting diode preparation and LED display screen preparation, relates to an LED display panel and an LED display, and in particular to an LED display panel and an LED display capable of eliminating dark lines. Background technique [0002] LED, that is, light-emitting diode, emits energy through the recombination of electrons and holes, and can efficiently convert electrical energy into light energy. It has multiple advantages such as small size, rich colors, low energy consumption, and long service life. New solid-state light sources for general lighting. LED displays based on LEDs have many advantages such as high stability, long service life, and low operating temperature. At the same time, they also inherit the advantages of LEDs such as low power consumption, color saturation, fast response, and strong contrast. Application prospects. [0003] Generally, an LED display is formed by splicing ...
