摘要： A cholesteric liquid crystal composite display device includes a cholesteric liquid crystal reflective display device and a transmissive display device. The transmissive display device is located below the cholesteric liquid crystal reflective display device. When the cholesteric liquid crystal reflective display device is displayed in a transparent state, the light transmittance of the cholesteric liquid crystal reflective display device is higher than that of the cholesteric liquid crystal reflective display device when it is displayed in a dark state through a rated driving mode. Thereby, the display of the cholesteric liquid crystal composite display device is made clearer and the display quality is improved.

摘要： A system of the present invention reduces the size and/or increases the efficiency of a display system or device that integrates or includes a display, for example, an LED display such as a microLED display and OLED display or an LCoS display into such system or device. Embodiments of the present disclosure include, but are not limited to, a display wherein the at least two pixels are four pixels comprising two green pixels, one blue pixel, and one red pixel, and wherein a pixel logic circuit maintains the red pixel in an on state while driving the two green pixels and the blue pixel in accordance with a field sequential color (FSC) pixel drive process or method.

摘要： A verifiable display is provided that enables the visual content of the display to be detected and confirmed in a variety of ambient lighting conditions, environments, and operational states. In particular, the verifiable display has a display layer that is capable of visually setting an intended message for human or machine reading, with the intendended message being set using pixels. Depending on the operational condition of the display and the ambient light, for example, the message that is actually displayed and perceivable may vary from the intended message. To detect what message is actually displayed, a light detection layer in the verifiable display detects the illumination state of the pixels, and in that way is able to detect what message is actually being presented by the display layer.

摘要： An electro-optical apparatus 300 includes a first electro-optical panel 201 that is a segment panel, a first display driver 101 that drives the first electro-optical panel 201, a second electro-optical panel 202 that is a matrix panel, and is arranged to overlap the first electro-optical panel 201 in planar view of the first electro-optical panel 201, and a second display driver 102 that displays an image on the second electro-optical panel 202 by driving the second electro-optical panel 202. The first electro-optical panel 201 is arranged on the side from which an image is visually recognizable. The second display driver 102 outputs a drive voltage to a segment electrode of the first electro-optical panel 201.

摘要： A timing control chip includes a pulse signal generation module for generating first and second pulse signals, a data signal sending module having a data signal including valid and invalid data segments, and a synthesis module for synthesizing the first and second pulse signals into the invalid data segment to form a synthesized data signal and then transfer it to the data signal sending module. The data signal sending module is to connect a data driver chip to make the data driver chip decompose the synthesized data signal into the first and the second pulse signal, grab a state of the second pulse signal when the first pulse signal is at a first edge and control a polarity of an outputted driving voltage according to the grabbed state of the second pulse signal. The invention further provides a data driver chip and a driving circuit.
