Method for improving liquid crystal screen downwards angle of visibility and TV set with said method

Abstract

Disclosed a method for improving the lower angle of view of LCD screen and the TV with said method, comprise three steps as: inverting the LCD screen; rotating the image and the menu 180 degrees; outputting the image and the menu. In addition, said TV set comprises a LCD display with inverted LCD screen mounted in the TV case; a image processor for rotating the image and the menu 180 degrees; and a video signal processing circuit for driving said LCD display output the image and the menu. The invention via the inverted installment of screen and the inverted image by software operation, solves the problem of bad lower angle of view of LCD screen, so it has the practicality for the situations which need to hang the LCD screen. The invention has simple structure and easy realization while compared to the method without said invention, the image quality is improved significantly, and it has wider application and higher practicality.

Description

technical field [0001] The invention relates to a technical method capable of brightening the lower viewing angle of a liquid crystal screen. Background technique [0002] At present, most of the small-sized LCD screens under 20 inches use brightness enhancement film to increase the brightness of the screen. The direction of the rays of light scattered around is such that the direction of these rays is perpendicular to the LCD screen. However, using this method will result in a darker image when viewed from other directions, thereby losing viewing angles. The current small-sized LCD screen usually improves the brightness by losing the viewing angle. For those monitors used for desktops, since people usually watch the screen directly or from the left, right, and above, the increased brightness improves the performance of the display. People's viewing effect, and the loss of the viewing angle below will not cause much impact. However, in some special applications, such as o...

Problems solved by technology

[0003] In order to solve the problem in the prior art that the lower viewing angle of a liquid crystal display suspended at a high place is not conducive to people’s viewing due to its darker viewing angle, the present invention provides a new method for improving the lower viewing angle of the liquid crystal display by sacrificing the brightness of the upper viewing angle to improve the brightness of the lower viewing angle, thus solving the problem that the image is too dark when people watch it from below
