Problems solved by technology

[0004] The application number is 200820093301.3. The Chinese patent application discloses a kind of LED panel for indoor use. In order to solve the problem that the brightness of the LED display screen is too high to be viewed at a close distance, it provides a light-transmitting board for weakening the brightness of the LED display screen, which can Use atomized glass plate, light-transmitting plate of resin material, dimming glass plate, etc.
[0005] Although this solution solves the glare problem, the weakening of the light makes the gaps between the splicing of the LED unit boards more obvious, the product is not beautiful enough, and the display content is also blurred

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] see figure 1 , figure 2 , Figure 4 and Figure 6 .

[0034] The LED display screen that can be used at a short distance in the present invention is formed by splicing a plurality of LED unit boards 10 arranged vertically and horizontally. The LED unit board 10 includes a rectangular substrate 101 and a plurality of vertically and horizontally arranged LED luminous tube 102, the LED unit board 10 also includes a diffuser plate 103 covering the plurality of LED luminous tubes 102, the diffuser plate 103 is also rectangular, and the surrounding edges of the diffuser plate 103 are in line with the The surrounding edges of the substrate 101 are flush;

[0035] The outer surface of the...

Abstract

The invention discloses an LED display screen capable of being used in a close range manner. The LED display screen is spliced by a plurality of LED unit plates which are arranged vertically and horizontally and is characterized in that each LED unit plate comprises a rectangular substrate and a plurality of LEDs which are vertically and horizontally arranged on the substrate, each LED unit platefurther comprises a rectangular scatter plate covering the LEDs, and the peripheral edge of the scatter plate is parallel with the peripheral edge of the substrate; the outer surface of the scatter plate is provided with strip-shaped through grooves corresponding to the space among the rows and lines of the LEDs to form crisscross mesh gaps. The LED display screen has the advantages that by the scatter plate, light emitted by the LEDs can be subjected to diffuse reflection, and the dazzling phenomenon during close-range watching is avoided; slicing gaps on the whole LED display screen can be allowed to be not evident any more, and false seamless appearance is achieved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to an LED display screen that can be used at close range. Background technique [0002] LED is a semiconductor solid-state light-emitting device. When a forward voltage is applied to both ends, photons are emitted to generate light. Existing LED display screens are generally formed by splicing multiple LED unit boards arranged vertically and horizontally. After the front of each LED unit board is filled with glue, it is then spliced ​​on a box, and a power supply device is equipped at the same time to form an LED display. display screen. [0003] The existing LED unit board is composed of a rectangular substrate and a plurality of LED light-emitting tubes arranged vertically and horizontally on the substrate. The full-color LED display is composed of red, green and blue light-emitting points. Because the LED display The luminous point is extremely small (10mil*10mil) and very br...
