Problems solved by technology

Such as medical equipment, aerospace navigation, radar indication, polar coordinate display, high-resolution electronic map and aviation display, etc., it is often necessary to use a square TFT liquid crystal display with an aspect ratio of 1:1 or other ratios. However, due to the above For several reasons, this square or other ratio TFT liquid crystal display cannot be manufactured in a TFT-LCD panel factory. : 1 or other proportions of the production process, it is incompatible, if you want to manufacture, you must invest a huge amount of money again to carry out a certain scale of technical transformation of the factory, but the scale of investment and the market capacity of square TFT liquid crystal displays are in At this stage, it is not compatible, and it is difficult to recover the investment, and there is a great investment risk
Therefore, so far, except for specific military uses that do not consider investment risk (defense investment), few TFT-LCD panel factories are willing to produce such a square or other square with an aspect ratio of 1:1 through technological transformation. Proportional TFT liquid crystal display, resulting in a serious disconnect between market demand and production

Abstract

This invention discloses an active matrix LCD device with special proportion of width to length and its laser cutting process method, which can directly process square or any proportional TFT LCD device that are processed through the steps of breakdown, positioning, cutting, cracking, sealing and connecting.

Description

technical field [0001] The present invention relates to an active matrix liquid crystal display (hereinafter referred to as TFT-LCD) and a manufacturing method thereof, especially a manufacturing method of an active matrix liquid crystal display whose aspect ratio is not 4:3 or 16:9, specifically The invention relates to a special aspect ratio active matrix liquid crystal display and its laser cutting manufacturing method. Background technique [0002] At present, there are only two standard specifications for the aspect ratio of commercial active matrix liquid crystal display panels: 4:3 and 16:9, which are also the main specifications of liquid crystal displays or TVs currently on the market. It is widely used in most occasions. The aspect ratio of its screen size is determined according to the human eye's viewing habits of the aspect ratio of the observed image and the rules of the TV image scanning system. It is a historical formation. Traditional habits, once a habit i...
