摘要:
A liquid crystal display apparatus has a display section formed on a first substrate. The display section including a plurality of pixels disposed in a matrix pattern, a plurality of scan lines extending in a row direction and a plurality of signal lines extending in a column direction. One pixel is connected at each cross point between the scan and signal lines and each pixel includes a semiconductor active element and a pixel electrode. A signal line driver circuit is disposed at opposite end portions in the row direction and includes semiconductor active elements for driving the scan lines. A scan line driver circuit is disposed at opposite end portions in the column direction and includes semiconductor active elements for driving the signal lines. A transparent second substrate is disposed opposing the first substrate and a liquid crystal layer is sandwiched between the first and second substrates. An insulating black color shading film is formed on an inner surface of the second substrate and covers at least a partial area of the signal line driver circuit.
摘要:
A liquid crystal display device includes a panel having pixel electrodes arranged at intersections of a plurality of signal lines via switching elements for transmitting display data and a plurality of scanning lines for transmitting control signals, and a control circuit for controlling the panel. The liquid crystal panel is divided into first pixel regions and second pixel regions adjacent to the first pixel regions. The control circuit carries out impulse driving in which the control signals transmitted to each of the scanning lines are activated two times in one frame period for displaying an image. The control circuit writes the display data in either one of the pixel regions and writes reset data in the other pixel regions when the control signals are activated once of the two times. By writing the reset data in the pixel regions, the display data written in an immediately preceding frame are reset. In consecutive frames, the display data written in the pixel regions are always reset in one frame period. Therefore, blurring in a moving image can be alleviated. Since writing the display data and the reset data is carried out separately in the first pixel regions and in the second pixel regions, flicker is prevented from occurring in a display screen.

摘要:
A voltage having the positive polarity and a voltage having the negative polarity are alternately applied to a pixel between a counter electrode and a pixel electrode. A counter electrode voltage (Vcom) generating circuit or a source signal generating section is provided each of which controls effective voltages to be applied to the pixel for an identical tone so that an effective voltage having the positive polarity and an effective voltage having the negative polarity are asymmetrically applied to the pixel for all of the tones which can be displayed. The counter electrode voltage (Vcom) generating circuit or the source signal generating section shifts a counter electrode voltage Vcom-A or a source voltage by 0.3 V or more from a voltage causing the effective voltages to be symmetrically applied to the pixel.
