20080212011 | Display device having a board for a connector for inputting of video data and a board for mounting a display control circuit and manufacturing method thereof - In a display device forming a board for mounting a connector which allows inputting of video data thereon and a board for mounting a display control circuit to be connected to the connector thereon on a surface of a display module opposite to an observation side, the board for mounting the connector thereon and the board for mounting the display control circuit thereon are physically separated from each other and, further, an area of the board for mounting the display control circuit thereon is set smaller than an area of the board for mounting the connector thereon. | 09-04-2008 |
20080303770 | Liquid Crystal Display Device - A counter voltage supply circuit has an inverting amplifier that inversely amplified a voltage detected from a specified part of a counter electrode of a liquid crystal display panel and supplies the amplified voltage to a counter voltage supply end of the counter electrode. The inverting amplifier includes an operational amplifier having a feedback resistor connected between an inverting input terminal and an output terminal. The feedback resistor includes a first resistor, and n resistors each of which is connected parallel to the first resistor via a switching element. As the n switching elements are selectively turned on and off by a switching element control circuit in accordance with a scanning position, the resistance value of the feedback resistor is varied and the gain of the operational amplifier is changed. Cross-talk due to coupling noise to the counter electrode generated by AC driving of a video voltage and deterioration in display quantity of a display image on the liquid crystal display panel can be prevented. | 12-11-2008 |
