摘要

An image display device includes: a display; gate signal lines including a first pixel row and a second pixel row; a gate driver; data signal lines; a source driver; and a controller that determines whether the second pixel row has correlation with the first pixel row in an image. When determining that the second pixel row has the correlation with the first pixel row, the controller causes the source driver to supply the data voltage corresponding to the first pixel row, causes the gate driver to supply the gate signal to write the data voltage in the first pixel row, and causes the gate driver to supply the gate signal to write the data voltage corresponding to the first pixel row in the second pixel row.

說明書

Specifically, liquid crystal panel 20 is connected to a plurality of flexible wiring boards (not illustrated) on which source driver 24 is mounted. A plurality of gate drivers 25 are mounted on liquid crystal panel 20.

As illustrated in FIG. 2, liquid crystal panel 20 including image display region 21 includes a plurality of data signal lines SL, a plurality of gate signal lines GL, and a plurality of thin film transistors TFT.

Image display region 21 is constructed with a plurality of pixels P arranged in a matrix form. One pixel P is constructed with a plurality of subpixels each of which serves as a display unit region. In the first exemplary embodiment, one pixel P is constructed with three subpixels of a red subpixel PR, a green subpixel PG, and a blue subpixel PB arranged in a row direction. A pixel electrode and a common electrode (not illustrated) are formed for each pixel P. In each pixel P, pixel capacitance (liquid crystal capacitance) is generated by the pixel electrode and the common electrode.

The plurality of data signal lines SL are provided for each pixel column 23 in image display region 21, and are provided to write a data voltage in the pixels in selected pixel row 22. The plurality of data signal lines SL extend in a column direction (vertical direction), and are arranged in the row direction (horizontal direction).

The plurality of gate signal lines GL are provided for each pixel row 22 in image display region 21, and provided to select the pixel row in which the data voltage corresponding to image data is written. The plurality of gate signal lines GL extend in the row direction (horizontal direction), and are arranged in the column direction (vertical direction).
