Problems solved by technology

[0006] However, when the experimental batch is put into production, it needs to go through the alignment process and ODF (One Drop Fill) process, and then use the inspection machine to detect the alignment angle of the experimental batch, so as to make corresponding adjustments to the process parameters of the shipping batch before proceeding to production. It takes quite a long time (at least 6 hours) from putting into production to detecting the alignment angle. During this period of time, the production cannot be carried out while waiting for the batch to be shipped. As a result, the loss of production capacity and the decline of production efficiency will inevitably result.

Abstract

The invention provides an alignment angle detection apparatus comprising a marking unit and a standard angle comparison part. The marking unit has an annular protrusion structure, and is coaxially arranged at the end portion of an alignment roll shaft in a sleeving manner. The standard angle comparison part is arranged on the blank zone of a substrate motherboard provided with a PI layer. When the alignment roll shaft rolls for alignment, the marking unit is in contact with the blank zone and draws a trace line in the blank zone through scratching, and the trace line and the standard angle comparison part are compared so as to determine the angle value of the trace line. The invention also provides an alignment angle detection method by the use of the alignment angle detection apparatus.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display panels, in particular to an alignment angle detection device and detection method. Background technique [0002] With the rapid development of electronic products towards lightness, thinness and miniaturization, almost all kinds of portable electronic products use liquid crystal displays (Liquid Crystal Display, LCD) as display terminals, especially in camcorders, notebook computers, desktop computers, In products such as smart TVs, mobile terminals or personal digital processors, liquid crystal displays have become an important component of electronic products. [0003] The liquid crystal display mainly includes a liquid crystal panel and a backlight module, wherein the liquid crystal panel includes a thin film transistor (ThinFilmTransistor, TFT) substrate and a color filter (ColorFilter, CF) substrate formed in a box, and a liquid crystal layer filled therebetween. [0004] In t...
