Abstract
The present invention is related to a liquid crystal display. The liquid crystal display includes a display panel, a plurality of pixels formed on the display panel, a sensing unit disposed among the pixels and generating a sensor data signal based on a touch to the display panel, a plurality of image data lines connected to the pixels and transmitting image data signals, and a sensor data line connected to the sensing unit and transmitting the sensor data signal. The sensor data line is separated from an image data line adjacent thereto with respect to the pixel.
Claims22
A liquid crystal display comprising:
- a display panel;
- a plurality of pixels formed on the display panel, including a first pixel and a second pixel, each pixel including a switching element and a pixel-electrode, each pixel having a left side and a right side, wherein the corresponding switching element of a given pixel is located either closer to the left side or closer to the right side of its respective pixel;
- a sensing unit disposed so as to be sandwiched between the first pixel and the second pixel and structured for generating a sensor data signal based on a localized touch to, or on a localized light change imposed on the display panel;
- and
- a plurality of image data lines each directly connected to corresponding ones of the switching elements of corresponding ones of the pixels, the data lines transmitting corresponding image data signals and comprising a first image data line directly connected to the first pixel and a second image data line directly connected to the second pixel,
- wherein the first pixel is disposed on the left side of the sensing unit, the second pixel is disposed on the right side of the sensing unit, the first image data line is disposed on the left side of the first pixel, the second image data line is disposed on the right side of the second pixel, the switching element of the first pixel is located closer to the left side of its pixel and the switching element of the second pixel is located closer to the right side of its pixel.
A display device comprising:
- a first panel,
- a second panel facing the first panel;
- an image scanning line formed on the second panel;
- first and second image data lines formed on the second panel and intersecting the image scanning line;
- first and second thin film transistors (TFTs) directly connected to the first and second image data lines, respectively;
- first and second pixel electrodes connected to the first and second TFTs, respectively, each of the first and second pixel electrodes having an asymmetric structure allowing for disposition of the respective first or second TFT immediately adjacent to that pixel electrode;
- a sensor scanning line formed on the second panel;
- a sensor data line formed on the second panel and intersecting the sensor scanning line;
- and
- a third TFT directly connected to the sensor scanning line and the sensor data line,
- wherein the first and second pixel electrodes are respectively arranged on the left and right sides of the third TFT so as to thereby sandwich the third TFT between them and so as to have bilateral symmetry with respect to the so-sandwiched third TFT, and
- wherein the first and second image data lines are formed on the left side of the first electrode and on the right side of the second pixel electrode, respectively.
