摘要： A liquid crystal drive circuit, which makes it possible to display low resolution display data on a high resolution liquid crystal panel while expanding and/or centering the display data, is provided. A multiscan control signal is inputted to a latch address control circuit and a data control circuit to control latch signals and the display data so as to latch single pixel data into a plurality of latches at the same time. The display data are latched with the expanding and/or centering operation, and outputted in synchronization with a line clock after being converted to gray scale voltages. Accordingly, it is possible to realize the lateral expansion and/or the centering operation. Further, it is also possible to realize a longitudinal expansion by adding a latch circuit between a latch circuit and a liquid crystal applied voltage generation circuit, and by outputting the data in synchronization with an expanded line clock.

摘要： A display device for displaying display data including a display panel; a driving circuit which generates a gray-scale voltage corresponding to the display data and outputs the gray-scale voltage to the display panel; a scan driver which scans a line on the display panel to which the gray-scale voltage is output; and a control circuit which outputs the display data to the driving circuit and outputs a display control signal to the scan driver. A gray-scale display characteristic of the display data is changeable between a first state in which a difference in a brightness of the display panel between two adjacent display data values becomes smaller as a display data gray-scale increases, and a second state in which the difference in the brightness of the display panel between two adjacent display data values becomes larger as the display data gray-scale increases.

摘要： There are provided a liquid crystal driving circuit and a liquid crystal display device in which the display brightness and color variation to input display data values can be adjusted. Input display data of one line period are taken into a latch circuit (1) with a latch signal output from a latch address control circuit, and latch circuit (1) data are taken into a latch circuit (2) at the timing of a line clock. Further, the latch circuit (2) data are input to a decode circuit. In accordance with set data output from a set register which sets the set register setting data with a set register setting clock, a gray-scale voltage which is matched with data of each pixel is selected and output as a selection voltage from the decode circuit. The selection voltage is buffered in an amplifying circuit, and then a liquid crystal applying voltage is output.

摘要： A liquid crystal display device of the present invention capable of enlarging and displaying to a high picture quality even when display data having a lower resolution than a liquid crystal panel is inputted is provided with storage element groups every drain line within latches of a liquid crystal driver. A portion of the storage element groups simultaneously captures display data. In doing so, the same liquid crystal apply voltage is outputted from drain lines corresponding to these storage element groups. Storage element groups corresponding to neighboring drain lines then simultaneously capture display data so as to enlarge an image in the horizontal direction. The rate of enlargement can be regulated by changing the number of storage element groups simultaneously capturing display data. A scanning driver then simultaneously selects a plurality of rows with a select voltage being applied to the simultaneously selected rows of pixel elements in the same period so as to enlarge the image in the vertical direction. Enlarged displaying is therefore possible by the liquid crystal driver regulating an output period of the liquid crystal apply voltage even when rows are selected one at a time.

摘要： In a low power consumption data transmission circuit and method, and a liquid crystal display apparatus using the same, 24-bit display data is transmitted from a transceiver circuit to a receiver circuit through a transmission line so that the display data is displayed on a liquid crystal panel. The transceiver circuit has a holding circuit including an 8-stage shift register. The transceiver circuit outputs 24-bit data to the transmission line by use of first and second output circuits when data different from data held in the holding circuit is to be transmitted from the transmission line and outputs data indicative of a hold position in the holding circuit from the second output circuit when the same data as that held in the holding circuit is to be transmitted from the transmission line. When the data indicative of a hold position is transmitted and received, the receiver circuit decodes or restores the received hold position indicating data into 24-bit display data by use of data held in a holding circuit provided in the receiver circuit.
