Abstract: A display panel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel has a relatively large feed-through voltage change and relatively small transmittance, and/or the first sub-pixel has relatively large line impedance and relatively small transmittance. By means of this design, a degree of image flicker is reduced.

Abstract: A touch display panel and controlling method thereof are provided. The touch display panel includes a first substrate, a second substrate, a display medium layer, a first common electrode, and a pixel structure including a pixel electrode and a second common electrode. The first common electrode has a voltage signal. In a display mode, the pixel electrode is provided with a data signal so that a first voltage difference exists between the first and the second common electrodes. The arrangement of the display medium layer varies according to the data signal and the first voltage difference. In a touch mode, the second common electrode is provided with an indication signal whose waveform alternates between first and second voltage values. When the indication signal is at the first voltage value and a second voltage value respectively, a second and a third voltage differences exist between the first and second common electrodes.

Abstract: An in-cell touch display device includes an in-cell touch panel, a backlight module driving circuit, a backlight module, a gate driving circuit, a touch processing circuit and a control circuit. The in-cell touch panel includes a plurality of gate lines and a plurality of touch sensing units. The control circuit is used for defining a plurality of gate line driving periods separated from each other in the time and at least one touch sensing period in a frame period. The touch sensing period is between two adjacent gate line driving periods. During the gate line driving periods, the control circuit controls the gate driving circuit to drive the gate lines sequentially and outputs a signal to the backlight module driving circuit to turn on the backlight module. During each touch sensing period, the control circuit controls the touch processing circuit to output a driving signal to the touch sensing units and outputs a signal to the backlight module driving circuit to turn off the backlight module.
