PS (Photo Spacer) Photo-spacer material is a kind of photoresist used to create small patterns on a color filter with lithography processes. The function of photo-spacer is to keep a constant gap of a specific distance between the two glass substrates and generate the space for the principal material of a TFT-LCD display - liquid crystal. Many leading TFT-LCD companies have evaluated and introduced the photo-spacer product of Topgiga [...]

Positive Photoresist  Positive tone photoresist is used for the transfer of patterns of the designed layouts in TFT-Array substrate of a TFT-LCD - the functions of positive tone photoresist is to protect some regions of the substrate from chemical attack during the wet or plasma etching process. Regarding resolution, thermal stability, stripping ability and etching resistance, positive tone photoresist is superior to negative tone photoresist. Reducing the cost, the [...]

Please contact to Dolphin Chen for more information . Positive Tone Photoresist The demand of "Touch Panel" is getting bigger, and the application of it is more extensive than ever. Many new factories and existed factories for the manufacturing of TFT-LCD are devoted to the development of products of "Touch Panel" one after another.  Positive tone photoresist is used for the transfer of patterns of the designed layouts of wires [...]
