Technical Field

The utility model relates to the technical field of LED display equipment, in particular to an infrared touch frame and an LED touch display screen.

Background

The working principle of the infrared touch screen is that an infrared matrix in the direction X, Y is densely distributed before the infrared touch screen is closely attached to the screen, and whether infrared rays are blocked by an object or not is detected and the touch of a user is positioned through continuous scanning. The touch screen is characterized in that an outer frame is arranged in front of a display, and a circuit board is arranged in the outer frame, so that infrared emitting tubes and infrared receiving tubes are distributed on four sides of the screen, and an infrared matrix crossing horizontally and vertically is formed in a one-to-one correspondence manner. Every time a turn is completed, if all the infrared tubes are in communication, it means that everything is normal and there is no touch. When a touch is detected, a finger or other objects can block the transverse and vertical infrared rays passing through the coordinate position, when the X or Y-axis touch screen scans, the finger or other objects find and confirm that one infrared ray is blocked, the touch is possible, meanwhile, the finger or other objects immediately switch to another axis for coordinate rescanning, and if the other axis is found to have one infrared ray blocked, the finger or other objects can show that the touch is detected, and the position of the touch point on the screen is calculated and judged.

The LED spliced screen is also called an electronic spliced screen, is different from a liquid crystal spliced screen, mainly comprises an LED dot matrix and an LED pc panel, and displays characters, pictures or videos and the like which are wanted to be displayed through the on or off of LED lamps with various colors. The LED spliced screen is formed by splicing and combining a plurality of independent display screens, and the spliced LED spliced screen is used as a single display assembly.

Because the size of the spliced display device is uncertain, the infrared touch frame is mainly applied to a single display device, and the infrared touch frame used on the LED spliced screen is fewer. The patent application document with the application number 202010622622.3 discloses an LED intelligent interaction multimedia all-in-one machine, which comprises an LED display screen, an infrared touch assembly, a frame assembly and a functional module; the frame component is arranged around the LED display screen to form a rectangular frame, the frame component is of a hollow structure, and a first space and a second space are arranged inside the frame component; the infrared touch assembly is fixed in the first space, and the first space of the frame assembly protrudes out of the LED display screen, so that an infrared touch frame can be formed; the functional module is fixed in the second space; the frame component comprises an upper frame, a lower frame, a left frame and a right frame; the two ends of the upper frame are respectively connected with the top end of the left frame and the top end of the right frame through upper corner blocks. After the size of the display screen is increased, the length and the width of the display screen are correspondingly increased, the sizes of the upper frame, the lower frame, the left frame and the right frame of the frame assembly are relatively increased, the frame assembly is inconvenient to move and troublesome to install, meanwhile, great difficulty is brought to the installation of the infrared light-emitting element and the infrared receiving element of the display screen, labor is consumed, the workload is great, the cost is greatly increased, and meanwhile, the defects of great error, reduced sensitivity and the like of the touch control function of the display screen are overcome, so that the display screen is unfavorable for popularization and application to the market.
