Problems solved by technology

It can be seen that due to occlusion, the spatial consistency of the light shapes of red, green, and blue in the pixel unit becomes poor, which will greatly affect the viewing angle of the display screen
At the same time, the "integrated three-in-one" module also increases the cost due to the many components and processes involved.

Abstract

The invention relates to an integrated LED (light emitting diode) display unit panel with a large viewing angle. The integrated LED display unit panel comprises an LED display module. A driving IC (integrated circuit) is welded on a driving circuit board, the back surface of a circuit board is connected with the driving circuit board through socket strips, and LED wafers are fixed on the front surface of the circuit board. The integrated LED display unit panel is characterized in that the integrated LED display unit panel further comprises transparent face masks and shading layers; air outlet holes are reserved at the positions, corresponding to the LED wafers, of the shading layers; the shading layers are connected with the front surface of the circuit board tightly; the transparent face masks are inserted into the LED wafers; and the back surfaces, away from the LED wafers, of the transparent face masks are connected with the shading layers tightly. The integrated LED display unit panel has the advantages of large viewing angle, high contrast, low light loss, low production cost and the like.

Description

technical field [0001] The invention belongs to the field of LED flat panel display and relates to a display unit board of a high-density LED color display screen. Background technique [0002] In recent years, with the continuous improvement of people's viewing demand for display devices, high-end LED displays are developing towards high density. High-density LED display is generally considered to refer to a full-color LED display with a pixel pitch of less than 3mm, and its point density is greater than 111111 pixels / square meter. At present, there are two types of high-density LED display devices: surface mount (SMD) three-in-one modules and "integrated three-in-one" (ZL200720094395.1) modules. For the SMD method, on the one hand, each pixel needs to be packaged separately by high-end equipment, and the installation is more complicated, which increases the production cost; There is not much space for the layout, coupled with the requirements for display performance and ...
