Intelligent full-color glass display screen

Abstract

The invention provides an intelligent full-color glass LED (Light Emitting Diode) display screen and a glass LED display unit. An unpackaged driving IC (Integrated Circuit) bare chip and an LED wafer are reversely arranged on an ITO (Indium Tin Oxides) circuit using glass as a base board, so that the packaging process of the existing LED lamp bead and the existing driving IC is omitted; and the processing and installing process of a conventional display screen module is also omitted. Therefore a circuit on the glass is very simple, and almost no power consumption or almost no temperature is generated on the ITO circuit, so that the display image of the display screen is stable, and the small-space intelligent full-color glass display screen can be realized on a single-layer circuit.

Description

technical field [0001] The invention relates to the field of LED displays, in particular to a small-pitch LED intelligent full-color glass display screen and a display unit. Background technique [0002] The intelligent full-color glass display screen is a display screen used to display text, graphics, images, videos and other information by controlling LED (Light Emitting Diode), that is, light-emitting diodes, with transparent glass as the substrate. Compared with traditional technology, LED display has excellent characteristics such as high transparency, low working voltage, stable performance and large-scale expansion. Although the technology of intelligent LED glass display has been developed rapidly, it still belongs to the primary stage of industrial design and industrialization research. stage. [0003] The traditional LED full-color display screen is packaged with LED chips into DIP (in-line) LED lamps or three-in-one LED lamps packaged in SMD, together with drive ...

AI Technical Summary

Problems solved by technology

When the current passes through the longer and thinner ITO coating circuit, due to the large square resistance of the ITO coating (the ITO square resistance of the commonly used LED glass display: R□≥15Ω), heat loss and heat will be generated due to the large resistance It will also affect the image color reproduction of the LED display

[0005]Figure 3 is the schematic diagram of the driver board side circuit in the prior art. Obviously, the circuit board has many electronic components, too many external wires of the driver, and the layout on the glass is complicated, which makes installation inconvenient. LED The glass screen is prone to poor contact (dead light) problems during long-term use

At the same time, there are too many external wires, which also makes the dot pitch of the LED glass screen unable to be less than 25mm, and it is impossible to obtain an LED full-color glass display screen with good light transmittance and high-definition image effect.
