The invention provides a gate-in-panel display device capable of preventing deterioration of thin-film transistors during pause drive, as well as a method for driving the same. At the end of a drive period, an active clear signal is provided to thin-film transistors in unit circuits, each thin-film transistor being connected to either a first or second node at a gate terminal, thereby bringing the thin-film transistors into ON state. As a result, the voltages of the first and second nodes are set to a reference voltage. Thus, even if a pause period lasts for a long period of time, the gate terminals of the thin-film transistors are not subjected to sustained voltage application, leading to no threshold voltage shifts.

There is provided a display device that is capable of suppressing occurrence of brightness drop which is caused by refresh of a display image during pause driving. In a normal driving mode, input image data (SsD0) according to a continuous tone method is supplied to a source driver (310) through a data selector (230) as an image signal (SsD) for driver. On the other hand, in a low-frequency driving mode in which pause driving is performed, the input image data (SsD0) is converted into dithered input image data (SsD1) by a dithering processing circuit (220), and is supplied to the source driver (310) through the data selector (230) as the image signal (SsD) for driver. A gradation of the dithered input image data (SsD1) is represented in a pseudo manner by an area coverage modulation method by using two values of a maximum value and a minimum value that can be taken as the gradation value of the input image data (SsD0).

An electro-optic display has a plurality of pixels, each of which is capable of displaying two extreme optical states and at least one intermediate gray level. Each pixel is driven from an initial intermediate gray level to one extreme optical state and then to a first desired intermediate gray level, so producing a first image on the display. The pixel then remains at this first desired intermediate gray level for a finite length of time. The pixel is then driven from this first desired intermediate gray level to the opposed extreme optical state and then to a second desired intermediate gray level, so producing a second image on the display.

A touch sensing display device supporting a pixel driving period and a touch driving period in each frame period. The device comprises a display panel having data lines and touch sensing lines, the data lines coupled to pixels of the display panel. A data driving circuit drives data signals onto the data lines during the pixel driving period of the frame period. A touch readout circuit generates touch data of signals of the touch sensing lines during the touch driving period of the frame period, the touch driving period distinct of the pixel driving period. A supply voltage of the data driving circuit can be cut off during the touch driving period, and a supply voltage of the touch readout circuit can be cut off during the pixel driving period.

A circuit block of a driving circuit of a display device includes a first transistor that has a gate being connected to a first node having an active potential during an output period, and controls electrical conduction between a first clock signal line being applied with a first clock signal and the scanning signal line, a second transistor that has a gate being connected to a node having an active potential during a non-output period, and controls electrical conduction between the first node and an inactive potential line, and a third transistor that has a gate being connected to the fir at node, and controls electrical conduction between the second node and a first cyclic signal line applied with a first period signal having an active potential at the time of termination of the output period.

Waveforms for driving an electrophoretic display including a color filter between a viewer and the electrophoretic medium. Because the waveform results in each image update visiting the white state before the final state, the overall gamut is larger in aggregate and more predictable than simply driving the electrophoretic display including a color filter with the waveforms that are used for black and white grayscale displays.

Provided is a driving circuit for a touch display apparatus. The driving circuit includes: a main control unit, providing image data for image display at a first speed; a driving unit, receiving the image data and sending display data to the touch display apparatus according to the received image data; a data buffering module, disposed in the driving unit, sending the display data at a second speed higher than the first speed, and forming, due to the difference between the second speed and the first speed, a pause time for stopping sending the display data to the touch display apparatus during the process that the main control unit provides the image data; and a touch detection unit, performing touch detection of the touch display apparatus in the pause time.

The present invention provides a gate driving circuit and a driving method thereof, a display device, which relates to the field of display technology. The gate driving circuit may comprise a plurality of mutually cascaded shift register units and a pre-charging unit, the gate row drive scanning and touch control scanning of the plurality of mutually cascaded shift register units are performed alternately. By additionally arranging a pre-charging unit connected with the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished, the first stage of shift register unit can be pre-charged during the touch control scanning. In this way, the electric leakage phenomenon of the pull-up control node (PU point) of the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished due to a relatively long touch control scanning time interval between outputs of two rows of shift register units is avoided, thereby avoiding the defect of insufficient charging rate of row of pixels while ensuring touch control scanning of high report rate.

An electrowetting display device may comprise pixels that include: a hydrophobic layer portion disposed on a first electrode, electrowetting fluids overlying the hydrophobic layer portion, and a thin film transistor (TFT) that is in electrical contact with the first electrode. The electrowetting display device also comprises a display control circuit in electrical contact with a drain or a source of the TFT of each of the pixels to provide a drive voltage to the drain or the source of the TFT of each of the pixels, and a reset control circuit in electrical contact with the drain or the source of the TFT of each of the pixels to provide a reset voltage pulse to the drain or the source of the TFT of each of the pixels. A magnitude of the reset voltage pulse may be based, at least in part, on the drive voltage.
