Title:
DISPLAY DRIVE CIRCUIT AND DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2021/057161
Kind Code:
A1
Abstract:
A display drive circuit and a display screen, the circuit being applied to an LED display screen. The display drive circuit comprises a constant-current drive module (200) and an infrared chip (300). The input end of the constant-current drive module (200) is used to connect to a power supply (100); the output end of the constant-current drive module (200) is connected to the infrared chip (300), and the constant-current drive module (200) is used to supply a stable constant current to the infrared chip (300) so that the infrared chip (300) may operate normally. Compared to using a constant-voltage drive module to supply power to the infrared chip (300), the constant-current drive module (200) is capable of providing a larger current to the infrared chip (300), so that the infrared chip (300) operates stably and the brightness is uniform.
