摘要： An image display device includes: a first power supply line; a second power supply line; a plurality of pixel circuit; a driving circuit for supplying a data signal and a scanning signal; and a switch unit. Each pixel circuit includes: a driving transistor between the first power supply line and the second power supply line; a light emitting element controlled by the driving transistor; and a storage capacitor for storing the data signal and controlling the driving transistor. The driving circuit causes the storage capacitor to store the data signal and controls an intensity of light emission based on the data signal. The switch unit is provided at one of one end of the first power supply line and one end of the second power supply line to control whether or not to allow a current to flow from the first power supply line to the second power supply line.

摘要： A display device having an on-screen display (OSD) function receives a YUV video signal such as the camera video signal or broadcast video signal of YUV format from a camera or recording medium, receives an RGB-OSD signal from a circuit device (serial interface) of another system different from this YUV video signal, causes a memory within an OSD processor to store the OSD signal, converts an RGB video signal resulting from conversion of the YUV video signal to a panel-matched RGB video signal synchronized with a display synchronization signal, reads a panel-matched RGB OSD signal from the memory of the OSD processor in synchronism with this display synchronization signal, composes those RGB video signal and OSD signal, using an OSD composer, and supplies the resulting RGB composite video signal and the display synchronization signal to a display panel.

摘要： The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.

摘要： A dot matrix display system for multiple-tone displays, including a display device in which pixels are arrayed in a matrix shape, an LC (liquid-crystal) drive signal generator which converts color display data into LC display data, an 8-level data driver which selects one of 8-level voltages in accordance with the LC display data and then delivers the selected voltage, and an 8-level voltage generator by which the 8-level applied LC voltages to be applied to the pixels are produced so as to substantially make uniform color differences between the respectively adjacent tones of the multiple-tone displays. Owing to the substantially uniform color differences between the respectively adjacent tones, multiple-tone displays which are uniformly seen by the human eye can be obtained.

摘要： There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.
