LED driver board, display panel driver board and display device

Abstract

The invention relates to a light emitting diode driver board which is used for driving a light emitting diode module comprising at least one light emitting diode cluster. The light emitting diode driver board comprises a circuit board, a connector, a light emitting diode driver, a plurality of light emitting diode driving signal lines and a plurality of configuration information communication lines. The connector and the light emitting diode driver are arranged on the circuit board. The light emitting diode driving signal lines are connected between the connector and the light emitting diode driver, and the configuration information communication lines are connected between the connector and the light emitting diode driver and used by the light emitting diode driver to obtain configuration parameter information of the light emitting diode module. The light emitting diode driver is a programmable driver. The invention further provides a display panel driver board matched with the light emitting diode driver board for using and a display device. By the utilization of the configuration parameter information of the light emitting diode module, for example, obtained by the configuration information communication lines, a corresponding light emitting diode driving signal is provided for driving the light emitting diode module. Therefore, compatibility is high.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting diode driving board, a display panel driving board and a display device. Background technique [0002] With the development of science and technology, thin and light, power-saving information products have flooded our lives, and display devices have played a very important role in it.

Problems solved by technology

[0005] According to the different requirements of the application, each type of LED driver board 13' has a predetermined number of light strings and a fixed driving current of the LED module 12', and the panel drive circuit of the display panel driver board 11' is based on the LED The demand assessment of the driver board 13' calculates the number of LEDs required for each light string. Therefore, there is a one-to-one relationship between each LED driver board 13' and the LED module 12', resulting in There is a one-to-one relationship between 13' and the display panel driver board 11', therefore, the same LED driver board 13' cannot be matched with different types of display panel driver boards 11', and the compatibility is low

[0006] Therefore, it is necessary to provide an improved technical solution to overcome the technical problem of low compatibility between the display panel driver board and the LED driver board in the prior art
