Problems solved by technology

However, the multiplexer itself has a high equivalent impedance
Therefore, when the conventional flat-panel display has high resolution or high frame rate (frame rate), so that each pixel is only allocated a short data writing time, the conventional flat-panel display will face the inability to charge the pixel to the expected voltage Potential problem

Embodiment Construction

[0052] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0053] figure 1 It is a simplified functional block diagram of the low impedance display 100 according to an embodiment of the present invention. The low-impedance display 100 includes a source driver 102, a gate driver 104, a plurality of horizontal driving lines GL[1]-GL[n], a plurality of multiplexing driving lines ML[1]-ML[m], and a plurality of data lines DL[ 1 ]˜DL[n], a plurality of first pixel groups 110 and a plurality of second pixel groups 120 . The first pixel group 110 includes a first pixel P1 and a second pixel P2, and the second pixel group 120 includes a third pixel P3 and a fourth pixel P4. The horizontal driving lines GL[ 1 ]˜GL[n] are used to respectively receive control signals Sc[ 1 ]˜Sc[n] from the gate driver 104 . The multiplexing driving lines ML[ 1 ]˜ML[m] are used to respectively receive multiple...

Abstract

A low impedance display includes a first pixel group, a second pixel group, and a first multiplexed driving line. The first pixel group includes a first pixel and a second pixel. The second pixel group includes a third pixel and a fourth pixel, wherein the first pixel group and the second pixel group receive data signals from the data lines. The first multiplex driving line is coupled to the firstpixel and the third pixel and is used for receiving a first multiplex signal. The first multiplex driving line is further used for controlling the first pixel and the second pixel to receive data signals in sequence and controlling the third pixel and the fourth pixel to receive data signals in sequence.

Description

technical field [0001] The invention relates to a display, in particular to a display without a multiplexer between a source driver and a data line. Background technique [0002] In order to save cost, a traditional flat panel display will set a multiplexer between the source driver and the data lines, so that a larger number of data lines can be driven by the source driver with fewer output pins. However, the multiplexer itself has a high equivalent impedance. Therefore, when the conventional flat-panel display has high resolution or high frame rate (frame rate), so that each pixel is only allocated a short data writing time, the conventional flat-panel display will not be able to charge the pixel to the expected voltage potential problem. [0003] In view of this, how to provide a flat panel display that can be applied to high resolution and high frame rate is a problem to be solved in the industry. Contents of the invention [0004] The invention provides a low imped...
