The substrate has a first surface, a second surface, a first bonding area and a second bonding area. The first patterned conductive layer disposed on the first surface includes first sensing series electrically insulated from each other. The second patterned conductive layer disposed on the second surface includes second sensing series electrically insulated from each other. The circuit board includes a rigid portion, a first flexible bonding portion and a second flexible bonding portion. The first flexible bonding portion and the second flexible bonding portion are electrically connected to the rigid portion. The first flexible bonding portion is electrically connected to the first sensing series in the first bonding area. The second flexible bonding portion is electrically connected to the second sensing series in the second bonding area. | 12-29-2011 |
| 20110285641 | TOUCH-SENSING DISPLAY PANEL AND TOUCH-SENSING COLOR FILTER SUBSTRATE - A touch-sensing display panel and a touch-sensing color filter substrate are provided. The touch-sensing display panel includes an array substrate, the touch-sensing color filter substrate, and a display medium. The touch-sensing color filter substrate is disposed above the array substrate. The display medium is arranged between the array substrate and the touch-sensing color filter substrate. The touch-sensing color filter substrate includes a substrate, a plurality of color filter films, a first electrode layer, and a second electrode layer. The substrate has an outer surface and an inner surface opposite to the outer surface. The color filter films are disposed on the inner surface. The first electrode layer is disposed between the substrate and the color filter films. The second electrode layer is disposed on the outer surface. | 11-24-2011 |
| 20080252504 | METHOD OF COMPENSATING CHANNEL OFFSET VOLTAGE FOR COLUMN DRIVER AND COLUMN DRIVER FOR LCD IMPLEMENTED THEREOF - A technique for removing vertical stripe artifacts generated in a Liquid Crystal Display (LCD) panel, more particularly a technique for compensating for and removing an inter-channel offset voltage of a column driver, which causes the vertical stripe artifacts, is disclosed. An offset voltage generated in each channel for driving each pixel of the LCD panel is detected for a whole signal path and offset voltages detected for all channels are compared and extracted according to a given timing sequence by a common signal comparator, thereby preventing the offset of the detection comparator and reducing a chip size of the column driver in contrary to the prior art. Moreover, an inter-channel offset voltage is detected in a digital circuit mode, thereby compensating for process variations in a semiconductor chip manufacturing process in circuit terms. | 10-16-2008 |
| 20080218496 | LIQUID CRYSTAL DISPLAY DEVICE - The present invention generally relates to an LCD (Liquid Crystal Display) device, and more specifically, to an LCD device which comprises a driving circuit comprising: a data comparator for storing video data inputted in a previous stage from a timing generator, comparing size of the stored previous video data with video data inputted in the current stage, and for outputting a compared pre-emphasis voltage control signal; and an operational amplifier for adding pre-emphasis voltages to analog signals inputted from a D/A converter according to the pre-emphasis voltage control signal of the data comparator to amplify/output the signals. | 09-11-2008 |
