Abstract
Description
technical field
[0001] The invention relates to a sensing structure of a display device and a manufacturing method thereof; in particular, to a touch sensing structure of a liquid crystal display device and a manufacturing method thereof. Background technique
[0002] Generally, the liquid crystal gap (Cellgap, about 0.4um) required by the sensing area (Sensor area) in the touch panel is much smaller than the liquid crystal gap (about 5um) in the non-sensing area, so the sensing area needs to be equipped with a sensor Protrusion to increase touch sensitivity. The sensing flange can be disposed on a color filter (CF) or a thin film transistor (TFT). However, due to the precision required in the process, it is generally manufactured by using a yellow light developing process, and the manufacturing cost is high.
[0003] In addition, in order to prevent the gap material (Spacer) from being scattered on the sensing flange (protrusion) during the spraying process and causing def...
