Abstract: The level of a storage capacitor line is changed between two types, an H level and an L level. As a result of this change, the voltage applied to a liquid crystal is shifted so that a sufficient voltage is applied to the liquid crystal to perform a display operation. Then, at least one of two voltage levels of the storage capacitor line is used in common with the potential of at least one of plurality of voltage levels which are used in vertical driver which drives the said selection line. Furthermore, the values of the storage capacitance and parasitic capacitance for the storage capacitor line are set within a specific range.

Abstract: The level of a storage capacitor line changes between two types, an H level and an L level. As a result of this change, the voltage applied to a liquid crystal is shifted so that a sufficient voltage is applied to the liquid crystal to perform a display operation. Then, by changing the voltage value of the difference between a first level and a second level, the contrast and screen brightness are adjusted. Furthermore, the capacitances generated at the locations where the two storage capacitor lines and the data line intersect are set to be substantially the same.

Abstract: This invention provides a liquid crystal display device where an excellent display can be obtained by using a supplemental capacitance coupling driving method. When at least either one of voltages of a pixel electrode for a common electrode before or after a potential of a supplemental capacitance line is changed lies within a transition region R as a region of voltages which largely change a liquid crystal capacitance CLC, correction of an image signal is performed by adding a changing amount of the potential of the pixel electrode by using CALL added with CLC after changed. This is because that CLC as one of components of CALL in an amount (CSC/CALL)×?V of the potential change of the pixel electrode caused by the potential change of the supplemental capacitance line changes.

Abstract: Disclosed is an IC chip using a glass substrate capable of being manufactured at a lower cost than the IC chip using from a semiconductor wafer. Further, where the body substrate of a display device is made of glass, the IC chip and the body substrate can have equal coefficients of thermal expansion, thus preventing the IC chips from peeling off and reducing the failure rate. Furthermore, the gate line driving IC applied to a display device can be arranged as an IC chip having a length approximately equal to the display area, therefore, mounting a plurality of IC chips as the gate driving IC is not required, thereby reducing the production cost. Still further, all gate lines can be extended in parallel from the IC chip so that no difference in the delay occurs among the gate lines and the size of frame of display device can reduced.

Abstract: Test data terminals R-DATA, G-DATA, and B-DATA are provided with respect to video signal lines VL-R, VL-G, and VL-B, via switches SW-R, SW-G, and SW-B, respectively. The switches SW-R, SW-G, and SW-B are turned ON by receiving an H level input signal supplied from a test terminal SW. Thus, a test of a panel is performed before an external IC is connected to the panel. When the external IC is connected to the panel, on the other hand, these terminals used for the test are fixed to an L level, thereby preventing abnormal operations.

Abstract: Video decoder decodes pictures B0, B1, I2, B3 of GOP-3 which have been read out from a recording medium along with recording of new compressed picture data onto the recording medium thereafter to further decode pictures B4, P5, B6 . . . to restore them. Namely, it is impossible to restore, only by the compressed picture data of pictures B4, P5, B6. . . , these pictures corresponding thereto. For this reason, picture data of pictures B4, P5, B6. . . which have not been caused to be missing by recording of new compressed picture data are re-encoded to generate new GOP. Thus, the video decoder decodes and restores those non-missing pictures on the basis of the pictures B0, B1, I2, B3 within the new GOP.
