Abstract

The invention is applicable to the field of light emitting diodes, and provides an LED display screen and a matrix type LED module. The matrix type LED module comprises a circuit board and a light emitting layer, a plurality of LED units forming a matrix is fixed on the front face of the circuit board, each LED unit comprises a red LED chip, a green LED chip and a blue LED chip, positive electrodes of red LED chips, green LED chips and blue LED chips of each column of the LED units are in conduction with the same bonding pad located on the bottom surface of the circuit board, negative electrodes of red LED chips of each row of the LED units are in conduction with the same bonding pad located on the bottom surface of the circuit board, negative electrodes of green LED chips of each row of the LED units are in conduction with the same bonding pad located on the bottom surface of the circuit board, and negative electrodes of blue LED chips of each row of the LED units are in conduction with the same bonding pad located on the bottom surface of the circuit board. According to the LED display screen and the matrix type LED module, welding points when the LED display screen is made are reduced, the production efficiency is improved, and the yield is high when the high density LED display screen is made.

Description

technical field [0001] The invention belongs to the field of light emitting diodes, and in particular relates to an LED display screen and a matrix LED module. Background technique [0002] Light Emitting Diode (LED) is a solid-state semiconductor device that can directly convert electricity into light. LED uses electric field to emit light, which changes the principle of incandescent tungsten filament and energy-saving lamps. The characteristics of LED are very obvious, long life, high luminous efficiency, no radiation and low power consumption. [0003] The spectrum of LEDs is almost entirely concentrated in the visible light band. The LED light source can use the principle of red, green and blue three primary colors. Under the control of computer technology, the three colors can have 256 gray levels and can be mixed arbitrarily, which can generate 256×256×256=16777216 kinds of colors, forming a combination of different light colors , changing, to achieve a variety of d...
