Embodiment Construction

[0055] In an exemplary embodiment of the present invention, the backlight driving module may select a driving parameter set from a plurality of preset driving parameter sets in response to different configurations of the backlight module of the display panel, so as to properly drive the backlight module of the display panel . One of the identification methods of the configuration of the backlight module is, for example, providing identification information by some pins of the connector of the backlight drive module, and then the processor module or the power conversion module judges the backlight module based on the identification information. configuration, so as to select the appropriate drive parameter set. In one embodiment, the backlight driving module can also detect or judge the configuration of the backlight module by itself to generate the driving parameter set. Hereinafter, several examples are presented to illustrate the present invention, but the present invention...

Abstract

A backlight driving module including a power converter module and a processor module is provided. The power converter module is configured to convert a first power to a second power to drive the backlight module according to a driving parameter set. The processor module is configured to provide the first power to the power converter module. One of the processor module and the power converter module determines a configuration of the backlight module by using identification information. The driving parameter set corresponds to the configuration of the backlight module.

Description

technical field [0001] The present invention relates to a driving module, and in particular to a backlight driving module. Background technique [0002] Generally speaking, the display panel is usually equipped with a backlight module to provide the backlight required for displaying images. The backlight module may have different configurations according to actual design requirements, for example, the number of light-emitting diode strings configured on the backlight module is different, or the number of light-emitting diode strings in each light-emitting diode string is different. The difference in the number of polar bodies. Different configurations of the backlight must be driven by different backlight driving modules. Therefore, corresponding to different configurations of backlight modules, the backlight driving module must correspond to a circuit structure design. Such an approach will increase the development time and cost of the backlight driver module. Conventio...
