Problems solved by technology

At this time, on the surface of the friction roller, there will be some problems after using adhesive tape, especially double-sided adhesive tape to attach the friction cloth. Leave some residue of double-sided tape adhesive, which can not only pollute the surface of the roller but also affect the effect of the friction treatment

Embodiment 1

[0023] Embodiment one: see attached figure 1 As shown, a rubbing machine device 10 for rubbing the alignment film of a liquid crystal display element is mainly composed of three parts: a table 11, a friction roller 12 and a support. A friction roller 12 is configured, and the friction roller is centered on a horizontal axis, and its two ends are supported by brackets so that it can rotate along the axis. In this embodiment, the friction roller 12 is a hollow cylindrical member made of strong fiber plastic, especially carbon fiber reinforced plastic (CFRP). A layer of metal film is formed on the outer surface of the cylindrical member. On the surface of the metal film, an adhesive tape, especially a double-sided tape, is used to wrap the rubbing cloth (not shown in the figure).

[0024] It is satisfactory to use carbon fiber reinforced plastic (CFRP), which can make the friction roller 12 have a strength of 250Gpa in the long axis direction and 200Gpa in the vertical direction...

Embodiment 2

[0027]Embodiment 2: A method of manufacturing a liquid crystal display element. First, a transparent electrode is arranged on the surface of a pair of glass substrates, and an alignment film is formed on the transparent electrode. The alignment film is made of an organic polymer material, especially a glass substrate. Made of materials such as POLYAMIDE. Because in general, the glassy amite compound is insoluble in the solvent, anhydrous acid and di-amin (Di-amin) compound are reacted in the solvent to synthesize the glassy amide (POLYAMIDE) acid, usually with Polishing water (Varnish) for painting as a solution of POLYAMIDE acid. After being coated on a glass substrate, it is dehydrated and hardened into POLYAMIDE through a heating and hardening process. In more detail, use the above-mentioned glass submigram (POLYAMIDE) acid N-base (Methyl)-2 hydrate (Hydrlide) and other medium (Amid) polar solvents and banana water (Cellosolve, The molecular formula is: HOH 2 CCH 2 OC ...

Abstract

The invention refers to a friction device and a making method to produce liquid crystal display component. The friction device: placing and fixing glass basic board on table, friction roller set on over the table, and the table opposite to the friction roller. The friction roller is a hollow columnar component made of strong quality fiber plastic, a layer of metal film is developed on outer surface of the columnar component, and a friction cloth adheres to the surface of the metal film. For ensuring the quality of friction mark, it sets non-contact shift sensor aimed at the outer surface of the friction roller, to determine polarization of the roller to reduce ill phenomena in the oriented friction procession.

Description

technical field [0001] The invention relates to a rubbing machine device in the manufacturing engineering of liquid crystal display elements and a manufacturing method for producing liquid crystal display elements using the device. The liquid crystal display element refers to a liquid crystal display unit in a liquid crystal display. Background technique [0002] The liquid crystal display element in the liquid crystal display includes two glass substrates, and transparent electrodes for applying an electric field to the liquid crystal layer are provided on the inner surfaces of the two glass substrates, and switching elements are provided for controlling the ON-OFF of the electric field, and color electrodes are provided for displaying colors. film, and various parts such as an alignment film are provided to align the liquid crystal molecules. The so-called alignment film is formed by resin materials such as POLYIMIDE coated on the glass substrate...
