Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] One embodiment of the present invention is a new type of LED display screen, which includes a mounting frame, several LED modules, and a mask; for example, the LED modules are strip-shaped LED light bars, LED light strings, or rectangular LED display modules, such as figure 1 As shown, the LED module is a rectangular LED display module with 3 rows and 4 columns. LED light bars form a light bar screen, or LED light strings form a light string screen, which has a lighter structure, and rectangular LED display modules form a modular screen, which has a firmer structure. In this way, when any one LED module fails, it can be quickly replaced, which is conducive to providing customers with standardized products and services.

[0024] Each of the LED modules is fixed on the installation frame; for example, the installation frame reserves so...

Abstract

The invention discloses a novel light-emitting diode (LED) display screen comprising an installation frame, a plurality of LED modules and a cover. The LED modules are fixed on the installation frame. A plurality of installation positions used for fixed external installation are disposed on the installation frame. Each LED module is provided with at least one printed circuit board (PCB), a plurality of LED lamps and drive chips of the LED lamps, wherein at least one LED lamp is arranged on one side of each PCB and each drive chip of each LED lamp is arranged on the other side of each PCB board. The cover is fixedly arranged on the at least four LED modules. According to the technical scheme, by means of the mode that the installation frame and the cover are combined, the LED display screen which is light, convenient and suitable for vehicle-mounted use can be manufactured and can be installed on the rear portion or a side portion of a vehicle.

Description

technical field [0001] The invention relates to the field of LED display, in particular to a novel LED display screen. Background technique [0002] There are two main types of existing vehicle-mounted LED displays, one is a smaller strip screen, which is placed on the roof or built in the compartment, and can only simply display a small amount of information; the other is a larger rectangular screen, usually It is relatively heavy and needs to be installed on the load compartment of the vehicle, which is too heavy and inconvenient to use. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a novel LED display screen. [0005] The technical solution of the present invention is as follows: a novel LED display screen, which includes a mounting frame, several LED modules, and a mask; each of the LED modules is fixed on the mounting frame; ...
