Title:
HARD SCREEN AND DISPLAY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/185463
Kind Code:
A1
Abstract:
A hard screen, comprising a hard material, a circuit arranged on the hard material, and a plurality of LED luminous bodies arranged on the hard material. Each LED luminous body comprises coded information of the LED luminous body. The circuit is of a three-wire system, comprising the following three types of wires: a first type of connecting wire, used for electrically connecting a power supply positive electrode/VCC end of each LED luminous body; a second type of connecting wire, used for electrically connecting a power supply negative electrode/GND end of each LED luminous body; and a third type of connecting wire, used for electrically connecting a data signal input pin DIN end of each LED luminous body so as to provide data signals, wherein each LED luminous body obtains, according to the coded information of the LED luminous body, a corresponding data signal for the LED luminous body from the data signals. The overall cost of the hard screen can be effectively reduced, the yield can be effectively improved, and even the light transmittance and the current bearing capacity can be improved.
