20100214272 | DISPLAY AND ELECTRONIC APPARATUS EQUIPPED WITH SAME - An active matrix display capable of compensating leaking current while maintaining the aperture rate is provided. The active matrix display device has a plurality of pixels arranged as a matrix, and each of the pixels includes a liquid crystal display element; a driving control switch for controlling the driving of the liquid crystal display element; and a storage capacitor for storing image data provided to the liquid crystal display element via the driving control switch. The display device is an active matrix display device comprising voltage-compensating means for applying a specified voltage to one end of the storage capacitor opposite to another end coupled to the liquid crystal display element in a maintaining period. | 08-26-2010 |
20120068991 | ACTIVE MATRIX DISPLAY DEVICES AND ELECTRONIC APPARATUSES USING THE SAME - A display device capable of preventing display noise from being induced in the first frame period after a power source is input thereto. The display device includes pixels arranged in a matrix formed by rows and columns. Each pixel includes a pixel electrode, a display element, a storage capacitor coupled to the display element through the pixel electrode, and a switch element. The display device further includes a capacitive storage (CS) driving device which is synchronized with the scan line driving device to switch a potential of each electrode between two values one row by one row. Each electrode is disposed opposite to corresponding pixel electrode through a storage capacitor and is coupled to a corresponding CS line. After a power source is input and before the first scanning operation is performed, the CS driving device sets a potential of each capacitive storage line to one of the two values. | 03-22-2012 |

20120300146 | DISPLAY DEVICE AND DISPLAY PANEL - A display panel is provided and includes gate lines, source lines, and pixel units. Each gate line extends in a first direction, while each source line extends in a second direction interlacing with the first direction. The pixel units are arranged to form a display array. Each pixel unit is coupled to three sequentially disposed gate lines and three sequentially disposed source lines. Each pixel unit includes pixels. For each pixel unit, the pixels between any set of the two adjacent gate lines are coupled to different gate lines and different source lines. For each pixel unit, the pixels between one set of the two adjacent source lines are coupled to the same gate line and different source lines, and the pixels between the other set of the two adjacent source lines are coupled to different gate lines and different source lines. | 11-29-2012 |

20150255030 | DISPLAY PANEL - A display panel comprises a display area, a plurality of scan lines and data lines, a data driving circuit and a demultiplexing unit. The scan lines and the data lines cross each other within the display area. At least two of the data lines have different capacitances. The data driving circuit outputs a plurality of control signal and a data signal. The demultiplexing unit includes a plurality of thin-film transistors coupled with the data driving circuit and the data lines. The thin-film transistors receive the data signal and transmit the data signal to the correspondingly coupled data lines through channel layers of the thin-film transistors according to the control signals. The channel layers of at least two of the thin-film transistors coupled with the at least two data lines have different widths. | 09-10-2015 |
