Abstract

The embodiment of the invention discloses an LED driving circuit and an LED display device, and belongs to the technical field of LEDs. Comprising a receiving card and at least one backboard signal driving unit. The receiving card sends a group of control signals to each backboard signal driving unit; the backboard signal driving unit comprises a plurality of groups of output ports connected with the lamp panel connector, receives a group of control signals, divides the control signals into a plurality of groups of sub-control signals, and outputs a group of sub-control signals to each group of output ports; wherein the signal type contained in one group of sub-control signals is consistent with the signal type contained in one group of control signals. According to the technical scheme, the control signals are transmitted from the receiving card to the lamp panel connector in the form of groups, so that the crossing among the control signal wires can be reduced, the generation of signal cross-division can be reduced, the quality of the control signals is ensured, and the radiation interference of a product can be reduced.

Description

technical field [0001] The present application relates to the field of LED technology, and in particular, to an LED driving circuit and an LED display device. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) has been widely used in display products, which can efficiently convert electrical energy into light energy. However, in the existing LED display products, the connection between the components is relatively simple, and there are many crossings between the traces of the control signals, which easily leads to crosstalk between the control signals, which not only seriously affects the signal quality, and it is easy to make the radiation interference of the product larger. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide an LED driving circuit and an LED display device, which are beneficial to solve the problem of large radiation interference of existing LED display products. [0004]...
