Display device and a driving method thereof

摘要

A display device including a display panel, a gate driver, a data driver and a signal controller. The display panel includes gate lines and data lines, the gate driver is connected to the gate lines, the data driver is connected to the data lines and the signal controller controls the display panel, the gate driver, and the data driver. The signal controller includes a timing controller and a low voltage differential signaling (LVDS) receiving unit. The timing controller includes a frame memory. The display device further includes an analog-to-digital (AD) board including an LVDS transmission unit, wherein the LVDS transmission unit transmits a signal identifying a stopped image or a moving image to the LVDS receiving unit, and in response to the signal identifying the stopped image, the signal controller maintains the display of the same image on the display panel by using the frame memory.

1. A display device, comprising:
a display panel including gate lines and data lines; a gate driver connected to the gate lines; a data driver connected to the data lines; a signal controller controlling the display panel, the gate driver, and the data driver, the signal controller including a timing controller and a low voltage differential signaling (LVDS) receiving unit and the timing controller including a frame memory; and an analog-to-digital (AD) board including an LVDS transmission unit, wherein the LVDS transmission unit transmits a signal identifying a stopped image or a moving image to the LVDS receiving unit, and in response to the signal identifying the stopped image, the signal controller maintains the display of the same image on the display panel by using the frame memory, wherein the signal identifying the stopped image uses a combination of at least two of a data enable (DE) signal, a vertical synchronization (VSYNC) signal, and a horizontal synchronization (HSYNC) signal of an LVDS transmission method to identity the stopped image.
