20090115463 | Buffer Circuit - A buffer circuit is provided, having an odd number of stages of inverting amplifiers, wherein the stages are capacitive coupled. A negative feedback path feeds back from an output terminal of the final stage of the inverting amplifiers to an input terminal of the initial stage. A reference current source is also provided. A first switch is provided between the adjacent stages of the inverting amplifiers and switched, depending upon a mode of operation. A second switch is provided for selectively driving at least a transistor(s) in the final stage to cause a current mirror circuit with the reference current source depending upon a mode of operation. | 05-07-2009 |
20090002355 | Active Matrix Liquid Crystal Display Device and Method of Driving the Same - The present invention is directed to an a.c. driven active matrix liquid crystal display device capable of inhibiting the aforementioned artifact of stripes as well as saving the power consumption, and a method of driving such a device. A selection switch SW controlled by a column selection circuit 50 enables selection of picture signal lines Sb to be connected to a picture signal source 40 by skipping, and since the picture signal lines are divided in two groups such as a group of odd numbered ones and the other group of even numbered ones so that the connection sequence of the groups of them are varied from one of two consecutive periods to another, vivid stripes are prevented from coming up simply upon the connection to the picture signal lines related with any specific color, thereby enhancing the quality of the resultant picture displayed. A plurality of picture signal lines which are selected by a plurality of picture signal selecting circuits may be arranged adjacent to one another. | 01-01-2009 |
20080252962 | Electronic Ink Display Device and Method for Manufacturing the Same - The invention provides an electronic ink display device having a panel structure of reduced thickness and enhanced moisture resistance and a method for manufacturing the same. The electronic ink display device has a first substrate ( | 10-16-2008 |
20080231620 | Active Matrix Display Device - A display device comprising an array of pixels, with gates of thin film transistors of the pixels in a row connected to a row conductor. Row driver circuitry provides row address signals for controlling the switching of the transistors of the pixels of the row including an ON gate voltage and an OFF gate voltage. Control circuitry shifts the ON gate voltage and the OFF gate voltage in dependence on drive and/or environmental conditions such as temperature and/or refresh rate. The control circuitry maintains a constant difference between the ON gate voltage and the OFF gate voltage. This allows the gap between the on and off voltages to be reduced, which results in power savings. The kickback voltage is kept constant so that kickback compensation is kept simple. | 09-25-2008 |
20080211999 | Transflective Liquid Crystal Display Device - A transflective display device has a color filter portion for each pixel which includes portions of two different thicknesses. In one implementation, both thicknesses are used for the reflective part of the pixel, and the relative thicknesses as well as the proportion of different thickness layers can be controlled to enable independent control of the color filtering characteristics in the reflective and transmissive modes of operation. Another implementation uses different portions of light absorbing material for the functions of pixel definition and height adjustment, but these may be achieved with a single patterned layer. | 09-04-2008 |
