Abstract: Active matrix display devices capable of improving aperture ratio of pixels and of smoothing intermediate colors are presented. An active matrix display device (1) has static random access memory (SRAM) devices and digital to analog converters (DAC), which are both allocated to each of sub-pixels (3) of a divided pixel. The SRAM stores an input digital data with over two bits, which can be used as gray level information for gray scale display by the respective sub-pixels. The input digital data is converted into analog data for display by the DAC. Gray scale display by the sub-pixels (3) can be performed based on gray scales determined by the analog data for display. The pixel can be used to display multiple gray scales according to combinations of areas and gray scales of the sub-pixels (3) in which one sub-pixel displays MSB gray scale data and a second sub-pixel displays LSB gray scales.

Abstract: A method of providing an LCD overdrive drive scheme comprises measuring a stabilised transmission level of an LCD display pixel corresponding to a target drive level. An overdrive transmission level is measured corresponding to an overdrive drive level. The measured overdrive transmission level is compared with the measured stabilised transmission level to determine if the overdrive drive level is too high or too low. An iterative process then changes the overdrive drive level until a suitable overdrive drive level is found. This is used to derive overdrive drive scheme parameters whcih are stored in a memory of the LCD device.
This method enables an overdrive scheme to be determined during use of the device. It can therefore take account of temperature and display ageing, without the effects of these being modelled.

Abstract: The present invention is related to an asymmetric aligned display having asymmetric viewing angles. The present invention provides a dual-view or 3D display capable of displaying two images of unrelated or related content along different directions with asymmetric viewing angles. The asymmetric viewing angles of the display device of the present invention can be realized by the introduction of multiple sub-pixel pitches into a single display To be more specific, the present invention provides an asymmetric aligned display by realizing the asymmetry design in the sub-pixel itself. Consequently, the angular extends of the respective viewing windows or images displayed along different directions can be different or asymmetrical. The asymmetric aligned display of the present invention is, therefore, capable of displaying images along different directions with asymmetric viewing angles and windows without affecting the outer boundaries of the viewing windows.

Abstract: A pixel driving circuit with threshold voltage and power supply voltage compensation. The pixel circuit includes a storage capacitor, a transistor, a transfer circuit, a driving element, and a switching circuit. The transistor has a gate coupled to a discharge signal and is coupled between a first node and a second node. The discharge signal directs the transistor to turn on and then discharges the storage capacitor in a first period. The transfer circuit transfers a data signal or a reference signal to a first node of the storage capacitor. The driving element has a first terminal coupled to a first voltage, a second terminal coupled to a second node of the storage capacitor and a third terminal outputting a driving current. The switching circuit is coupled between the driving element and a display element. The switching circuit can be controlled to diode-connect the driving element in a second period, allowing the driving current to be output to the display element in a third time period.
