DISPLAY PANEL DRIVER AND DISPLAY DEVICE HAVING THE SAME

摘要

A display device includes a data driver, line selectors, and a controller. The data driver provides data signals to output lines. The line selectors control connections between the output lines and data lines. The controller selects a normal driving mode or a low frequency driving mode as a panel driving mode and controls a scan driver, the data driver, and the line selectors based on the panel driving mode. Each line selector respectively connects the output lines to the data lines when the panel driving mode is the normal driving mode, and progressively connects one of the output lines to some of the data lines when the panel driving mode is the low frequency driving mode.

1. A display device, comprising:
a display panel including scan lines, data lines, and pixels; a scan driver to provide scan signals to the scan lines; a data driver to provide data signals to output lines; a plurality of line selectors to control connections between the output lines and the data lines; and a controller to select a normal driving mode or a low frequency driving mode as a panel driving mode for driving the display panel, and to control the scan driver, the data driver, and the line selectors based on the panel driving mode, wherein each of the line selectors is to respectively connect the output lines to the data lines when the panel driving mode is the normal driving mode and is to progressively connect one of the output lines to some of the data lines when the panel driving mode is the low frequency driving mode.
