Embodiment Construction

[0015] The specific implementation manners in the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 with figure 2 As shown, the sound-permeable LED display screen used for large LED screens in the present invention includes a PCB printed board 1 and a plurality of light-emitting pixels 2 fixed on the light-emitting surface 3 of the PCB printed board 1 by pasting. Among them, all the light-emitting pixels 2 are arranged on the surface of the light-emitting surface 3. Since the light-emitting diode lamp beads have the characteristics of low brightness, high contrast, and no reflection, the light-emitting pixels 2 in the present invention adopt surface-mounted light-emitting diodes, and the surface-mounted Type light-emitting diodes are fixed on the surface of the light-emitting surface 3 by pasting, and can emit red, green, blue, and white lights.

[0017] Such as image 3 As shown, the distribution and...

Abstract

The invention discloses a sound-transmission LED display screen applied to a large-sized LED screen and a sound transmission method. The display screen comprises a PCB and a plurality of light-emitting pixels arranged on the PCB, wherein the light-emitting pixels are surface-mounted light-emitting diodes and are fixed on a light-emitting surface of the PCB through adhesion, each adjacent four light-emitting pixels form a group and are adhered to the light-emitting surface of the PCB, and a sound-transmission hole penetrating through the PCB is formed in the middles of each adjacent four light-emitting pixels. According to the sound-transmission LED display screen, the areas of the sound-transmission holes are greatly increased, and the sound-transmission holes are formed by virtue of limited space among the light-emitting pixels, so that a good sound transmission effect is achieved, the wire distribution of the light-emitting pixels is not influenced, and meanwhile, the sound-transmission LED display screen has good sound transmission rate.

Description

technical field [0001] The invention relates to the field of movie screen display, in particular to a sound-permeable LED display screen and a sound-transmitting method for large LED screens. Background technique [0002] At present, in order to pursue the perfect fusion of picture and sound in various theaters, sound-permeable curtains have become the standard configuration of theaters (that is, the curtains are covered with small holes of uniform size and regular distribution), which can restore the real sound to the maximum extent. However, this method can only be used for curtains, and it cannot be realized for LED displays. The light-emitting pixels of the LED display are arranged in an array. If holes are randomly punched near the light-emitting pixels, the inner layer wiring will be affected, resulting in The screen function cannot be realized. Contents of the invention [0003] The object of the present invention is to provide a sound-permeable LED display screen ...
