Abstract

The present application proposes an adapter board and a display panel, wherein the adapter board includes a single-input multiple-output circuit, at least one storage circuit, and multiple power supply circuits, and the adapter board uses at least one storage circuit with a corresponding size and capacity to partition and store each lamp For the data signal of the board, multiple power supply circuits are used to output working voltages of different voltages to at least one storage circuit and multiple lamp panels. At the same time, the storage circuit is powered by the same power supply circuit, and each lamp board does not need to be equipped with storage circuits and power supplies. circuit, the number of storage circuits and power circuits is reduced, and the layout area and cost of each lamp board are reduced.

Description

technical field [0001] The present application belongs to the technical field of display panels, and in particular relates to an adapter board and a display panel. Background technique [0002] LED (light emitting diode, light-emitting diode) display panels are usually composed of multiple light panels. At present, in order to store data signals such as pixel data and correction data of each light panel separately, each light panel is equipped with a storage module. [0003] At the same time, in order to provide working power to the storage module, an additional power circuit may be required on each lamp board. [0004] The increase of power circuits and storage modules on the light board leads to an increase in the layout area and cost of the light board. Contents of the invention [0005] The purpose of the present application is to provide an adapter board, aiming to solve the problem of increasing the layout area and cost caused by separate power supply circuits and s...
