Embodiment Construction

[0056] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0057] Image 6 A flow chart is shown for explaining an LCD manufacturing method to which a drip injection method according to an embodiment of the present invention is applied. Figure 7 A perspective view is shown for explaining the liquid crystal dropping method according to the embodiment of the present invention. Figure 8 Indicates the state after liquid crystal instillation.

[0058] Although not shown, the present invention provides first and second substrates that have undergone an arraying process and a color filter process. The first and second substrates respectively include a plurality of thin film transistor (TFT) unit substrate regions and color filter unit substrate regions. After the arraying process and the color filter process are completed, the first substrate and the second substrate are respectively loaded on the...

Abstract

A device for controlling liquid crystal distribution, comprising: a platform and an adjustable temperature control device for controlling liquid crystal distribution in the platform, wherein the adjustable temperature control device is composed of a heating wire, which can control the temperature in the range of about 30°C to 120°C In this way, the gap between liquid crystal droplets can be narrowed.

Description

[0001] This application claims the benefit of Korean Application No. P2002-12489, filed March 8, 2002, and Korean Application No. P2002-12489, filed March 13, 2002, which are hereby incorporated by reference in their entirety. technical field [0002] The invention relates to a liquid crystal display (LCD), in particular to a method for controlling distribution of liquid crystals, which can maximize the distribution of liquid crystals in the process of dripping liquid crystals. The invention also relates to a manufacturing method of LCDs. Background technique [0003] With the development of information socialization, the demand for various forms of displays has been increasing. In order to meet these requirements in recent years, various flat display panels have been developed, such as liquid crystal displays (LCDs), plasma display panels (Plasma Display Panels, PDPs) ), ElectroLuminescent Display (ELD), Vacuum Fluorescent Display (Vacuum Fluorescent Display, VFD), etc., som...
