Abstract

Disclosed is a device for eliminating after image overlap blurring phenomenon between frames in the simulation of CRT impulse type image display with liquid crystal display (LCD), including first and second input control lines; first and second input data lines; first and second capacitors; a driving voltage output line; a first transistor including a first gate connected to a first input control line, a first source connected to a first input data line, and a first drain connected to a driving voltage output line, a first capacitor and the drain of the second transistor; and a second transistor including a second gate connected to a second input control line, a second source connected to a second input data line, and a second drain connected to a driving voltage output line, the drain of the first transistor and the second capacitor. The first and second capacitors are connected to ground respectively. The driving voltage output line supplies a simulation driving voltage to pixels of an LCD panel for displaying images and including a backlight unit with adjustable and controllable luminance and a backlight input voltage control line. The first and second input control lines are co…
