Abstract

The multi-channel voltage sensing circuit for pixel compensation includes: a plurality of channel circuits provided for a plurality of channels; and first and second dummy channel circuits disposed between the plurality of channel circuits, with some of the channel circuits interposed between the first and second dummy channel circuits, where the first and second dummy channel circuits receive a first reference voltage of a fixed level, and the first and second dummy channel circuits receive a second reference voltage of a fixed level. And provide an electrical connection with an adjacent channel circuit.

Description

technical field [0001] Various embodiments relate generally to compensating pixels of a display panel, and more particularly, to a multi-channel voltage sensing circuit for pixel compensation that is improved for sensing a display panel The multi-channel channel circuit of the pixel signal has uniform sensing characteristics. Background technique [0002] The display system includes a display panel, a driver and a timing controller. [0003] The driver converts the digital display data provided from the timing controller into analog source driving signals, and provides the source driving signals to the display panel. The driver is configured by a chip. [0004] The number of drivers configured in the display system may be determined in consideration of the size and resolution of the display panel. [0005] The display panel may be configured by an OLED panel. The OLED panel includes pixels configured by OLEDs. In this case, there may be deviations in electrical characte...
