A liquid crystal display device includes a liquid crystal display panel including a plurality of pixels, a voltage generator generating a gate on voltage and a gate off voltage, a gate driver generating a gate signal provided to the pixel using the gate on voltage and the gate off voltage, and providing the gate signal to the pixels, a data driver providing a data signal to the pixels, and a timing controller generating control signals that control the gate driver and the data driver. Each of the pixels includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. A voltage level of the gate off voltage provided to the red sub-pixel, a voltage level of the gate off voltage provided to the green sub-pixel, and a voltage level of the gate off voltage provided to the blue sub-pixel are different from one another.

The present disclosure relates to the OLED display technology. There are provided a pixel circuit, a driving circuit, an array substrate and a display device, which are supplied with the voltage by the light emitting operation voltage when the pixel circuit enters the light emitting stage, by inputting an inverse signal synchronized with the pre-charging control voltage at the input terminal of the light emitting operation voltage to ensure a stable output of the current by the circuit at the light emitting stage. Also, it does not require an arrangement of an external voltage input terminal which will affect the aperture ratio, thereby increasing the aperture ratio of the OLED employing the current-driven pixel circuit while ensuring the stable output of the current by the current-driven circuit, and thus increasing the lifetime of the OLED employing the current-driven pixel circuit.

The present disclosure relates to electronic displays and display components, specifically to a method of addressing more pixels with a smaller number of driver outputs while also allowing very narrow frames on three sides of a display. It further discloses a display driver integrated circuit capable of providing the signals required for the disclosed addressing method and display systems capable of being addressed by the disclosed method and display driver integrated circuit.

A driving circuit and an operating method thereof and a controlling circuit which are suitable for a knob apparatus are provided. The driving circuit includes multiple touch-sensing electrodes and a controlling circuit. The knob apparatus includes a knob and a touch panel. The knob is disposed on the touch panel. The touch-sensing electrodes and the controlling circuit are disposed in the touch panel. The touch-sensing electrodes are coupled to multiple pixel switches of the touch panel. The controlling circuit is coupled to the touch-sensing electrodes. During a touch period, the controlling circuit provides an offset voltage to a first touch-sensing electrode of the touch-sensing electrodes, such that a first pixel switch coupled to the first touch-sensing electrode maintains being turned off according to a touch-controlling signal and the offset voltage.
