Abstract

The invention relates to an adjustment device and an adjustment method for an output enable signal. The adjustment method comprises the following steps: according to the duty cycle of the output enable signal, filtering a first scanning signal and a second scanning signal to provide a first output scanning signal and a second output scanning signal; and if the second output scanning signal is converted into an enable quasi-phase from a disable quasi-phase before the first output scanning signal is converted into the disable quasi-phase from the enable quasi-phase, increasing the duty cycle ofthe output enable signal. Therefore, the re-write problem is prevented.

Description

technical field

[0001] The present invention relates to an adjustment technology for an output enable signal, and in particular relates to an adjustment technology for an output enable signal suitable for a gate driver. Background technique

[0002] In recent years, liquid crystal displays have become the mainstream of display products on the market due to their advantages such as low-voltage operation and no radiation. Generally speaking, a liquid crystal display mainly includes a gate driver, a source driver and a panel. It is worth mentioning that there is a problem of rewriting when the conventional liquid crystal display is driven, and the details are as follows.

[0003] figure 1 is a schematic diagram of a well-known rewriting phenomenon. Please refer to figure 1 , the signal G1_output is an output scan signal provided by the gate driver to the first scan line, wherein the first scan line is coupled to the first row of pixel transistors. The signal G2_output is a...
