Abstract

The invention discloses an LED cascaded transparent display screen. According to the specific technical scheme, the LED cascaded transparent display screen comprises a transparent substrate, a transparent conductive circuit, a miniature LED array with a control function, a silver paste line and an off-screen controller; a transparent signal line is cascaded with a plurality of columns of miniatureLEDs with the control function in an S-shaped mode to complete data transmission, and the off-screen controller is externally connected to supply data to the signal line; power lines are connected into the power supply ports of all LED chips in parallel; and at the edge of the screen, line ends of the power lines are connected in series through the silver paste line to be externally connected with a general power supply, grounding lines are connected into grounding ports of all the LED chips in parallel, and at the edge of the screen, the line ends of the power lines are connected in series through the silver paste line to be connected with the ground directly. The power supply problem of an LED cascaded transparent screen is solved, and the problems that too many cascaded LED chips exist, the power supply pressure is large, and consequently the luminous LED chips are insufficient in luminance and are delayed are effectively solved.

Description

technical field [0001] The invention relates to the technical field of electronic display screens, in particular to an LED cascade transparent display screen. Background technique [0002] At present, the transparent LED display technology is developing, and the LED display technology is becoming more and more perfect, especially the LED cascaded transparent display. A transparent signal conductive line is connected in series with multiple columns of micro-LEDs with control functions. Each column of LEDs has an independent power supply and grounding. . The number of wires has been greatly reduced, the off-screen drive system has been removed, and the screen-making technology has been greatly simplified. However, there are too many cascaded LED chips, and the power supply pressure is high, which cannot guarantee the performance and life of the chips, and will affect the presentation effect of multimedia advertisements on LED displays. Contents of the invention [0003] Ac...
