Embodiment Construction

[0035] The output enable signal in the prior art is only designed to adjust the pulse interval of the scan drive signal output by the scan driver, so as to ensure that the TFTs of the next scan line are turned on only after the TFTs of the previous scan line are turned off, avoiding charging Something wrong happened. After considering the needs of the analog system, such as the vehicle market, for the Zoom function, the present invention proposes an image zoom method, which can increase the function of the flat-panel display module, solve the problem of image zoom, and improve the comfort of the flat-panel display viewer. , and can avoid charging errors of thin film transistors and improve image quality. The present invention will be described below with examples.

Abstract

The invention discloses an image scaling method and a device thereof. The method comprises that the following steps: providing a plurality of scanning periods; providing a plurality of scanning data, wherein, an i scanning period provides an i scanning data; and in a j scanning period, a j scanning data drive at least two adjacent scanning lines, wherein, the i and the j are positive integers. The image scaling method and the device of the invention have the advantages of improving the function of plane display module groups, solving the problems of the image scaling, and improving the comfortableness of the viewers of the plane displays; moreover, the invention can avoid the charging fault of thin film transistors, thus improving image quality.

Description

technical field [0001] The present invention relates to an image scaling method, and in particular relates to an image scaling method and device capable of improving image quality. Background technique [0002] With the development of high technology, video products, especially digital video or image devices have become common products in daily life. In these digital video or image devices, the display is an important component to display relevant information. Users can read information from the display, or further control the operation of the device. [0003] At present, the display that attracts the most attention is a flat panel display developed in conjunction with optoelectronic technology and semiconductor manufacturing technology, such as a liquid crystal display (Liquid Crystal Display, LCD). Due to the advantages of low-voltage operation, no radiation scattering, light weight, and small size, liquid crystal displays have become the main subject of display research...
