Abstract: A process for patterning thick film electrically functional patterns using a photosensitive polymer layer. A tacky photosensitive layer (104) is applied onto a substrate surface. The photosensitive layer (104) is imaged with a pattern (106) using actinic radiation, the exposed areas (107) of the photosensitive layer become hardened and non-tacky. A subsequent application of a thick film composition sheet (101 on 102) will cause the thick film (101) to adhere to the remaining tacky areas (104). Upon peeling the sheet (102), a thick film print pattern (101) will be produced. This step is followed by a processing profile prescribed by the thick film composition used which results in a pattern having electrically functional properties. The invention also extends to a process wherein a thick film composition is recovered from a used sheet.

The second gate driving signal generation unit(200) outputs the multi-gate driving signal having a first and a second high level by synthesizing the second gate driving signal and the first gate driving signal. The switching unit(300) is connected between the output terminal of the first gate driving signal generation unit(100) and the output terminal of the second gate driving signal generation unit(200). And, the controller(400) enables the second driving signal generation unit(200) while turning off the switching unit(300) and disables the second gate driving signal generation unit(200) so as to output the first gate driving signal.
