    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.

    Abstract: An LCD panel includes first and second substrates, signal lines, pixel structures, first, second, and third color filter pattern layers, a light-shielding pattern layer, and a liquid crystal medium. The second substrate has first and second light-shielding regions and first, second and third light-transmissive regions. The first and second light-shielding regions define the first, second and third light-transmissive regions. The first color filter pattern layer is correspondingly located in the first light-transmissive regions and the first light-shielding regions. The second color filter pattern layer is correspondingly located in the second light-transmissive regions and the first light-shielding regions. The first and second color filter pattern layers are stacked together in the first light-shielding regions. The third color filter pattern layer is correspondingly located in the third light-transmissive regions. The light-shielding patterned layer is correspondingly located in the second light-shielding regions and on the first, second, and third color filter pattern layers.

    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.
