Problems solved by technology

[0005] However, with the decrease of the dot pitch, the process difficulty and cost of conventional solutions such as mask or gap filling increase sharply. At present, the existing technology usually adopts the solution of encapsulating black glue on the surface of small-pitch or micro-pitch products. , but while these schemes increase the contrast, they also cause a decrease in the brightness of the display screen. At the same time, the lost brightness causes an increase in the temperature of the display screen.

Abstract

The invention discloses an LED display module and an LED display screen. The LED display module comprises an LED lamp panel, an optical filling layer and an optical film layer. The sides, away from the circuit board, of the LED light-emitting pieces are provided with a light emitting face and the optical filling layer covers the plane where the light-emitting face is located and fills the gaps between the LED light-emitting pieces. The optical film layer comprises an ink coating; a plurality of through holes are formed in the ink coating, the through holes penetrate through the ink coating in the thickness direction of the LED display module, and an ink area is formed between every two adjacent through holes; and the ink coating covers the optical filling layer, the light-emitting faces correspond to the through holes one to one, and the ink areas correspond to the gaps. The ink area shields the gap, and the contrast ratio and the black screen consistency are improved. The brightness loss is reduced through the through holes, and the temperature of the LED display screen is influenced due to the fact that the lost brightness is finally converted into heat, so that the brightness loss is reduced, the converted heat is reduced, and the influence on the temperature of the LED display screen is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an LED display module and an LED display screen. Background technique [0002] Light emitting diode (light emitting diode, LED) display screens have the advantages of wide color gamut, high brightness, large viewing angle, low power consumption, and long service life. Therefore, in the display field, LED display screens are widely used. For example, more common securities trading and financial information display, airport flight dynamic information display, port and station passenger guidance information display, stadium information display, road traffic information display, power dispatching and vehicle dynamic tracking and other dispatching command center information display, shopping malls Display of business publicity information and advertising media products in service areas such as centers. [0003] No matter which field the LED display is applied to, it is a m...
