Abstract

The invention discloses a display screen driving chip, a display screen driving circuit and a display screen driving method. The display screen driving chip comprises a signal transmission module, a voltage control module, a driving voltage generation module and a constant current driving module; the signal transmission module accesses a display control signal, and performs first decoding processing, serial-to-parallel conversion and second decoding processing on the display control signal to obtain a display driving signal and a display configuration signal; the voltage control module generates a voltage driving signal according to the display driving signal; the driving voltage generation module adjusts the input voltage of the light-emitting module according to the voltage driving signal; the constant-current driving module performs constant-current control on the light-emitting module according to the display configuration signal. The display screen driving chip can flexibly adjustthe input electric energy according to the power requirement of the light emitting module, so that the light emitting module is in a rated operation state, the flexibility is high, the light source display quality and the driving stability of the light emitting module are guaranteed, and the energy-saving effect is achieved.

Description

technical field [0001] The application belongs to the technical field of electronic circuits, and in particular relates to a display driving chip, a display driving circuit and a display driving method. Background technique [0002] With the rapid development of electronic technology and the continuous improvement of people's living standards, LED (Light Emitting Diode, light-emitting diode) display screens are widely used in various industrial technology fields. LED display screens not only bring people a good visual experience, but also As a large-scale outdoor broadcasting media, LED display screen has a large area and long playing time, and its power consumption is quite considerable; with the national requirements for energy conservation and environmental protection, LED display screens need to adopt the latest international energy-saving design concepts, taking into account costs, etc. Various factors provide users with a complete set of large-screen energy-saving solu...
