Method of manufacturing ultra slim panel

The present invention relates to a technology for etching a panel, such as a display panel, into an ultra-thin panel. The technology is used for making the large panel with features of good surface roughness, thickness uniformity and transparency, and is suitable for manufacture. The present invention provides a manufacture method of an ultra-thin panel. The display panel is firstly washed in an alkaline solution, the 16Mum/minutus is used as the upper limit of the etching speed and the panel is etched in a sinking way, thus the panel has good surface roughness, and after the final washing process the surface of the panel is detected by imaging, the thickness is detected in a non-contact way. In order to make up for vulnerability, a protection film is adhered on the panel and the subsequent process is performed.
