Embodiment

[0020] Embodiment: a method for expanding the viewing angle of a liquid crystal display image, comprising the following steps:

[0021] 1) Carry out signal analysis and processing on the analog image signal of the liquid crystal display, and decode the analog image signal to form a digital image signal in matrix form;

[0022] 2) converting the digital image signal into an inverted digital image signal by an image processing method of matrix space transformation;

[0023] 3) Encoding the inverted digital image signal to form an analog image signal in matrix form and output it to the LCD screen for display.

[0024] A method for expanding the image viewing angle of a liquid crystal display is specifically as follows: the image is sampled and quantized at equal intervals by an ADC (Analog-Digital Converter) to form discretized image data, and the image is represented by f(x, y) , where f represents the quantized value of the image, x represents the row of the image, and y repre...

Abstract

The invention relates to an extending method of a image view angle of a liquid crystal display (LCD), which comprises the following steps: 1) analyzing and processing analog image signal of the LCD, and encoding the analog image signals to form matrix type digital image signals; 2) converting the digital image signals into inverted digital image signals by an image processing method of matrix space transformation; and 3) encoding the inverted digital image signals to form the matrix type analog image signals to be output to the LCD to be displayed. A liquid crystal screen of the LCD is arranged in a shell of the LCD at a lower view angle, high-voltage strips are arranged at the right side of the inside of the shell, and LCD lines are connected below the liquid crystal screen in the shell when seen from the back. Compared with the prior art, the brightness, the contrast and the color level of images when a liquid crystal television is watched from the lower view angle are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and in particular relates to a method for expanding the image viewing angle of a liquid crystal display and a liquid crystal display thereof. Background technique [0002] For traditional CRT monitors, the fluorescent powder on the screen is bombarded by electrons to emit light, and the light is evenly emitted in all directions, so the brightness and color of the CRT monitor do not change significantly with the viewing angle. The images we see on liquid crystal displays are firstly a white light source emitted by the backlight. After the light source passes through the polarizer, liquid crystal and alignment layer, the output light has directionality. The principle is very similar to Blinds. That is to say, most of the light is emitted vertically from the screen, so when viewing the liquid crystal display from a certain larger angle, the original color cannot be seen, or even all...
