Problems solved by technology
[0004] Aiming at the development trend of the above-mentioned touch screen (process simplification, cost reduction) and solving the problem of liquid crystal panel glass thinning (since the transparent electrode layer is attached to the liquid crystal display layer, protection is required during the thinning process), the purpose of the present invention is to provide A single-sided etching method for liquid crystal panel glass, which is also applicable to other etched glasses requiring single-sided protection

Embodiment approach
[0051] As an embodiment of the present invention, such as image 3 Shown, a kind of single-side etching method of liquid crystal panel glass comprises the following steps:
[0052] Process A: Select liquid crystal panel glass that can be etched on one side. The condition that can be etched on one side is that the thickness of one side is > 0.1mm (such as Figure 4 As shown, LCD glass is liquid crystal panel glass, which is a liquid crystal display layer composed of a C / F substrate (that is, a color filter) and a TFT substrate. The thickness of one side is the thickness of C / F substrate or TFT substrate. At present, the thickness of the thinnest single side can be 0.1mm).
[0053]Before process B, the side of the liquid crystal panel glass selected through process A that needs to be preserved is cleaned by soaking. The cleaning equipment adopts a PVC automatic cleaning machine (the Chinese name of the PVC automatic cleaning machine is a pre-etching cleaning machine). The main...

The present invention discloses a single-side etching method for a liquid crystal panel glass. The method comprises the following steps: A, selecting a liquid crystal panel glass capable of being subjected to single-side etching, wherein a condition of the liquid crystal panel glass capable of being subjected to single-side etching is a single-side thickness of more than 0.1 mm; B, carrying out film adhering protection on a side of the selected liquid crystal panel glass, wherein the side of the liquid crystal panel glass requires remaining; C, adopting an etching device to carry out etching on the liquid crystal panel glass treated through the step B; D, carrying out a film removing treatment on the etched liquid crystal panel glass; and E, cleaning the film removed liquid crystal panel glass. With application of the method to process the liquid crystal panel glass, the problem of liquid crystal panel glass thinning in the prior art can be effectively solved. In addition, the method is applicable for other etching glasses requiring side protection.
Description
technical field [0001] The invention relates to the field of liquid crystal panel etching, in particular to a single-side etching method for liquid crystal panel glass. Background technique [0002] At present, in the field of FDP display, LCD panel glass is widely used in display terminals such as computers, TVs, and mobile phones. With the market demand, liquid crystal displays are developing toward light weight and high definition. In order to meet these characteristics and requirements, most liquid crystal display panels adopt the method of thinning the liquid crystal panel glass. At present, the thinning technology of liquid crystal panel glass is mainly based on chemical etching, supplemented by physical grinding. Moreover, such chemical thinning is uniform thinning. At present, there are four main etching methods for balanced thinning: 1. Dipping; 2. Side-Spray; 3. Cascade; 4. Top-Spray ). [0003] With the rapid development of the market, application terminals su...
