Problems solved by technology

However, the touch-type flat-panel display device using the photosensitive gap material will undergo permanent deformation due to the relationship between material properties, such as recovery rate, elastic coefficient, etc., after many times of pressing and releasing, which will affect the support of the liquid crystal gap. Flat panel display devices produce display brightness unevenness (mura) and capacitance variation (capacitance variation)
All of these are not conducive to the further application and development of touch-sensitive flat panel display devices.

Embodiment Construction

[0028] The present invention provides a sensing structure of a display device and a manufacturing method thereof. A spacer and a sensing bump (bump) are arranged on a touch panel liquid crystal gap (Cell gap) to form a sensing area (Sensor) by using fixed-point configuration technology. area). In the sensing structure of the display device and the manufacturing method thereof of the present invention, it is preferable to arrange conductive particles between the substrates to form sensing bumps and sensing regions by using fixed-point arrangement technology. The conductive particles applied to the sensing structure of the display device of the present invention preferably include but are not limited to metal particles or particles coated with indium tin oxide (ITO), that is, all conductive particles that can conduct between the sensing structures , all belong to the so-called conductive particles of the present invention. The "fixed-point configuration technology" mentioned he...

Abstract

The invention discloses a display device response structure and its manufacturing method. It includes the following steps: mixing many conduct particles in the solution; setting the solution on the second conduct cushion of the second base plate; removing the solvent to make at least one conduct particle stay on the conduct layer; parallel setting the first base plate on the second one. Thus the display device response structure includes the first and second base plates, at least one conduct particle. The former two respectively have the first and second conduct cushion each which can form many response areas with the conduct particles. The invention can solve the problem caused by bad sensitization clearance material reply ratio, overcome the defect caused by standing clearance material on the sensing flange, omit yellow light developing technology for sensitization clearance material and sensing flange, reduce manufacturing cost.

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...
