Abstract

A device for improving picture quality of TV consists of wide screen TV used in 4:3 display mode, pantograph to output synchronized signal and clock signal and modulation unit to provide aped regulation signal to image field and its outside field. It is featured as only modulating speed of image field but not for side field to eliminate raise phenomenon occurred at border of image picture and side picture so as to improve picture quality.

Description

technical field [0001] The present invention is an invention related to a TV picture quality improving device, in particular to a TV picture quality improving device relying on speed modulation to improve the TV picture quality. Background technique [0002] Such as figure 1 As shown, the traditional image quality improvement device consists of the following parts: [0003] The image output part (1) that receives the image signal and converts it into a color signal output; accepts the color signal converted by the above image output part (1), and adjusts the brightness adjustment part (2) of the corresponding signal brightness; increases the above brightness adjustment part according to a predetermined degree (2) The output color signal is transmitted to the display driver (3) of the display (4); the grayscale signal (Y) input to the above-mentioned image output unit (1) is accepted, differentiated and amplified to a predetermined level, and output Velocity modulation sect...
