The image processor is configured to process image data for image display via the display panel. An arrangement of sub-pixels of a pixel in an odd-numbered pixel column of the display panel is different from an arrangement of sub-pixels of a pixel in an even-numbered pixel column of the display panel.

The driving transistor includes a control terminal, a first terminal, and a second terminal, and controls supply of current to a light emitting element, which is connected to the first terminal and emits light in accordance with the current amount, in accordance with a signal voltage applied to the control terminal. The switching unit can switch a conduction and non-conduction state, and, by being brought in the conduction state, forms a path that bypasses the light emitting element so that the current is not supplied to the light emitting element. The control unit performs control so that the switching unit is brought in the non-conduction state after the signal voltage is written into the control terminal, and controls a potential of the control terminal in synchronization with the control of the switching unit.

Disclosed are a driving circuit, a driving method and a display device. The driving circuit (100) comprises: a data writing circuit (101), configured to, under control of a first scanning signal received at the first scanning signal end, write a data signal received at the data signal end into the first node; a control circuit (102), configured to, under control of a third scanning signal received at the third scanning signal end (SCAN3), write a data signal received by the first node (N1) into the second node (N2); and a driving sub-circuit (103), configured to, under control of a data signal received at the second node (N2), use a driving voltage received at the driving voltage end (Vdd) to drive the light-emitting component 104.

A display device includes: pixels, each of the pixels including at least one light emitting element and a first transistor configured to supply a driving current to the at least one light emitting element; a sensing unit configured to sense a driving current of the first transistor, which corresponds to a data voltage applied to one pixel from among the pixels, the sensing unit being configured to detect a luminance of the light emitting element, which corresponds to the driving current; a gamma calculator configured to receive the driving current and the luminance of the light emitting element from the sensing unit, to calculate a gamma changed based on the driving current and the luminance of the light emitting element, and to provide, to a memory, the gamma changed based on the driving current and the luminance of the light emitting element.

A light emitting display device and a compensation method thereof, wherein an optical characteristics detection portion overlapping a signal line is provided in a subpixel, and the optical characteristics detection portion is connected to one of source voltage lines used by the subpixel, whereby optical characteristics of the subpixel can be determined without loss in effective area of an emission portion and to easily compensate for an afterimage of a display panel.

A demultiplexer gate driver circuit and a display panel are provided. The demultiplexer gate driver circuit aims at the problem that the output amplitude of the m sub-gate drive signals divided from the gate drive signal by the demultiplexer module is low, which results in a poorer All Gate On function, when the GOA circuit of the demultiplexer module is used to achieve the All Gate On function. The full-on control module is improved by connecting the full-on control module to the m sub-gate drive signals divided from the gate drive signal. The m sub-gate drive signals are directly controlled by the full-on control module to output the high potential at the same time, and there is only one threshold voltage consumption from the full-on control signal to the sub-gate drive signals. The effect of the All Gate On function is effectively improved.

In various examples, a low-latency variable backlight liquid crystal display (LCD) system is disclosed. The LCD system may reduce latency and video lag by performing an analysis of peak pixel values within subsets of pixels using a rendering device, prior to transmitting the frame to a display device for display. As a result, the display device may receive the peak pixel value data prior to or concurrently with the frame data, and may begin updating the backlight settings of the display without having to wait for a substantial portion of the frame to be received. In this way, the LCD system may avoid the full frame delay of conventional systems, allowing the LCD system to more reliably support high-performance applications such as gaming.

A backlight driving device and an operating method thereof are provided to drive multiple backlight zones of a backlight panel. The backlight driving device includes an interface circuit and a driving circuit. The interface circuit receives main backlight data corresponding to a first backlight zone from a former stage device. The driving circuit drives the first backlight zone according to a main current level in a display refresh period of a backlight frame period, does not drive the first backlight zone in a demotion blur period which is prior to the display refresh period, and drives the first backlight zone according to a compensation current level in a vertical blanking period which succeeds the display refresh period. The driving circuit determines the main current level according to the main backlight data, and the compensation current level is lower than the main current level.
