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

Embodiment 1

[0059] As shown in Figures 1, 2, 5, 6, 7, 8, 9, and 10.

[0060] A square active-matrix liquid crystal display (as shown in Figures 1 and 2), which adopts a finished active-matrix liquid crystal display whose rows and columns as shown in Figures 5 and 6 are drawn from unilateral electrodes or as shown in Figures 7 and 8 The finished product active matrix liquid crystal display shown is cut, and the aspect ratio of display 22 is 1: 1 (also can be arbitrary ratio), and one side of display 22 is a flush shape cutting edge, and sealing glue 14 is packaged on the cutting edge, The sealant 14 is respectively in contact with the upper polarizing plate 5, the upper glass substrate 3, the liquid crystal material 7, the lower glass substrate 4, and the lower polarizing plate 6 of the display 22 (as shown in FIGS. 1 and 2).

[0061] The manufacturing method of above-mentioned square (or aspect ratio is non-4: 3 and 16: 9 ratio) active matrix liquid crystal display is:

[0062] A non-sta...

Embodiment 2

[0084] As shown in Figures 3, 4, 5, 6, 7, 8, 9, and 10.

[0085] A square active matrix liquid crystal display (as shown in Figures 3 and 4), which adopts a finished active matrix liquid crystal display whose rows and columns as shown in Figures 5 and 6 are drawn from unilateral electrodes or as shown in Figures 7 and 8 The finished product active matrix liquid crystal display shown is cut, and the aspect ratio of display 22 is 1: 1 (also can be any ratio), and one side of display 22 is the staggered cutting edge, is packaged on the staggered cutting edge The sealing glue 14, the sealing glue 14 is either in contact with the upper glass substrate 3 and the liquid crystal material 7, or in contact with the lower glass substrate 4 and the liquid crystal material 7, as shown in Figures 3 and 4 .

[0086] The manufacturing process of this embodiment is basically the same as that of Embodiment 1, the difference is that the grooves ground on the upper glass substrate 3 and the lower...

Abstract

This invention discloses a square or any random proportion size active matrix LCD and its process method. It can directly product the square or any proportion size TFT LCD, which on the original base is processed through the steps of breakdown, positioning, grinding, clearing, cracking and sealing.

Description

technical field [0001] The invention relates to an active matrix liquid crystal display and a manufacturing method thereof, in particular to a manufacturing method of an active matrix liquid crystal display with a non-standard aspect ratio of 4:3 or 16:9, specifically a non-standard Dimensional active-matrix liquid crystal displays and methods of milling and manufacturing the same. Background technique [0002] At present, the aspect ratio of commercial active matrix liquid crystal display (hereinafter referred to as TFT-LCD) panel size is only two standard specifications of 4:3 and 16:9, which is also the main specification of LCD monitors or TVs we currently sell in 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 is formed, the...
