Abstract


TFT-LCD displays are now widely used flat panel display (FPD), one with low power consumption, thin profile, light weight and other features. With the development of LCD technology, desktop LCD monitors, notebook LCD monitors, handheld displays and large-size LCD TVs have become increasingly popular. In response to various types of thin LCD monitors trends, including monolithic glass thickness from popular 0.7t, 0.63t gradually thin as 0.5t, 0.4t 0.3t even less, the use of such glass substrates have been produced extensive production. The existing thickness of the substrate held monitor is usually about 0.4t, so the need for such products thinned. This paper describes the development of TFT-LCD display and its structure and principle, a brief introduction to the LCD panel manufacturing process; subsequently focuses on the content of the substrate thinning treatment technology, chemical etching discuss ways thinning thinning technology of LCD panels Related Content: Introduction to the chemical etching substrate thinning technology classification and its advantages and disadvantages; combined with the actual situation of the company opted Lcascade waterfall stream substrate thinning technology way our production of LCD panels for thinning treatment experiments, each experiment the necessary analysis results. Through the use of Lcascade waterfall stream thinning thinning technical means visual inspection of the liquid crystal panel display inspection and analysis related adverse LCD panel and improved design experiments to solve the substrate thinning process problems and defective mode, the focus is thinning After the uniform thickness of the liquid crystal panel and TFT-side glass substrate, and the cause Dimple solutions. S1 through appropriate changes to our production line to cut engineering module assembly engineering process parameters to meet the requirements of the production of a liquid crystal panel and after thinning module, so that our existing back-end processing lines no longer need to perform complex transformation of the premise , so that you can produce 0.5t to 0.7t glass substrate capacity, greatly increasing our competitiveness in the industry. Through the assembled thin LCD module assembly of various reliability tests proved that using Lcascade waterfall stream substrate thinning technology to produce thin LCD panels and modules fully meet the production level. Finally, the thin substrate conveying means discussed studies to prove the use of PP-BOX conveying good delivery method can be thinned after the LCD panel. This paper presents a thin liquid crystal panel solutions both Lcascade waterfall stream substrate thinning technical means. The contents of this article by the Division I thin LCD panel product strategy provides technical support, but also for industry colleagues made the relevant technical reference.
