Abstract
Description
Technical Field
[0001] This invention relates to the technical field of LED displays, and more particularly to a MiniLED backlit display. Background Technology
[0002] A light-emitting diode (LED) is a semiconductor electronic component that converts electrical energy into light energy. It features low energy consumption, low heat generation, and high stability, and is commonly used in illuminated displays such as LED screens or advertising signs. A typical LED display screen consists of LED dot matrix modules, dimmer chips, and circuit boards.
[0003] In LED displays, the pixel arrangement is usually a rectangular column. In the display, each pixel can be displayed by combining multiple colors using RGB. The number of pixels per unit area determines the resolution. A common technique is to increase the number of pixels per unit area by reducing the size of the dot matrix module. This requires the dot matrix module to be continuously reduced in size to meet the requirement of increasing the number of pixels, which increases the research and development cost. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a MiniLED backlit display screen to solve the problem of high cost caused by the difficulty in increasing the number of pixels in LEDs.
[0005] Based on the technical problems existing in the background art, the present invention proposes a MiniLED backlight display screen, including a panel and triangular pyramidal lenses arranged on the panel. The edges of each row of triangular pyramidal lenses are arranged in parallel to form an arrangement group. Multiple arrangement groups are arranged in parallel to each other to form a display module. Three light-emitting groups are installed on the edge of each triangular pyramidal lens. The three light-emitting groups can emit light towards the triangular pyramidal lens and refract it onto the side of the triangular pyramidal lens facing the west panel.
[0006] Preferably, a partition is provided on the side of the panel facing the triangular pyramid lens. The partitions are arranged sequentially along the edge of the bottom surface of the triangular pyramid lens to form a single triangular prism cavity. The three light-emitting groups are installed on the three sides of the cavity respectively.
[0007] Preferably, the angle between the side of the triangular pyramid lens and the panel is 45 degrees.
[0008] Preferably, the base of the triangular pyramid lens is an equilateral triangle.
[0009] Preferably, the side surface of the triangular pyramid lens is the incident surface, and the bottom surface is the exit surface.
[0010] Preferably, the light-emitting group emits horizontal light rays that illuminate the incident surface of the triangular pyramid lens, and the light rays are refracted and exited from the exit surface of the triangular pyramid lens.
[0011] Preferably, the partition is made of a non-transparent material.
[0012] Preferably, the height of the partition is higher than the height of the triangular pyramid lens.
[0013] Preferably, a cover plate is installed at the top of the partition.
[0014] Compared with existing technologies, the MiniLED backlit display proposed in this invention, by adopting the above-mentioned technical solution, achieves the following technical effects:
[0015] This invention can increase the number of pixels per unit area within the same area, improve the rational arrangement of pixels, enhance the display effect of the display screen, and reduce research and development costs. This invention can reduce the area of each pixel unit while maintaining the edge length of the pixel unit. It can reduce the area of the pixel unit and increase the number of pixel units under the same light-emitting group installation requirements, thereby improving the display effect.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0020] Example
[0021] Please refer to Figures 1-2This invention proposes a MiniLED backlit display screen, including a panel 1 and triangular pyramidal lenses 2 arranged on the panel 1. The edges of each row of triangular pyramidal lenses 2 are arranged in parallel to form an arrangement group 100. Multiple arrangement groups 100 are arranged in parallel to each other to form a display module. Three light-emitting groups 3 are installed on the edge of each triangular pyramidal lens 2. The three light-emitting groups 3 can emit light towards the triangular pyramidal lens 2 and refract it to the side of the triangular pyramidal lens 2 facing the west panel 1. In summary, the three light-emitting groups 3 correspond to the three colors of red, green and blue respectively. Each lens is equivalent to a pixel. The lenses are equivalent to the arrangement group 100 combined to form a whole display screen.
[0022] In specific implementation, refer to Figure 1 , Figure 2 A partition 4 is provided on the side of panel 1 facing the triangular pyramid lens 2. The partitions 4 are arranged sequentially along the edge of the bottom surface of the triangular pyramid lens 2 to form a single triangular prism cavity 200. The three light-emitting groups 3 are respectively installed on the three sides of the cavity 200 partitions 4. In this scheme, the partitions 4 provided on the edge of the triangular pyramid lens 2 can prevent the light source from scattering in the single cavity 200. The partitions 4 are made of non-transparent material. At the same time, they can protect the triangular pyramid lens 2. The partitions 4 can provide mounting points for the light-emitting groups 3, which is convenient for the installation of the light-emitting groups 3. In this application, the light-emitting group 3 is a light-emitting diode.
[0023] In specific implementation, refer to Figure 1 The angle between the side of the triangular pyramid lens 2 and the panel 1 is 45 degrees. In this application, after the light-emitting diode illuminates the triangular pyramid lens 2 horizontally, the light will be transferred to the bottom of the triangular pyramid lens 2 through the principle of refraction. The angle between the side of the triangular pyramid lens 2 and the panel 1 can be other angles, but the optimal angle is 45 degrees.
[0024] In specific implementation, refer to Figure 1 , Figure 2 The base of the triangular pyramid lens 2 is an equilateral triangle.
[0025] In specific implementation, refer to Figure 1 , Figure 2 The side surface of the triangular pyramid lens 2 is the incident surface 21, and the bottom surface is the exit surface 22.
[0026] In specific implementation, refer to Figure 1 , Figure 2 The light-emitting group 3 emits horizontal light rays that illuminate the incident surface 21 of the triangular pyramid lens 2. After refraction, the light rays exit from the exit surface 22 of the triangular pyramid lens 2. In summary, the light sources of the three light-emitting groups 3 will converge at the exit surface 22 to produce the desired color.
[0027] In specific implementation, refer to Figure 1 , Figure 2The height of the partition 4 is higher than that of the triangular pyramid lens 2. In this scheme, the partition 4 can protect the triangular pyramid lens 2 and prevent light leakage from the light source.
[0028] In specific implementation, refer to Figure 1 , Figure 2 A cover plate 5 is installed on the top of the partition 4.
[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
