- Title:The Reliability Improvement of Drive Characteristic Evaluation for Large Size Touch Panel
- Eun Woo Lee and Yun Su Lee (Kyungpook Nat'l Univ., Korea)
Abstract: Recently, a study on the touch panel is progressive in various fields, but it has been mainly focused on the structure and fabrication of the sensor. The various touch panels must meet the requirements associated with the displays and UI. In addition, research and development must be carried out taking into account the commercialization. For this reasons, it is important to correctly understand the operating characteristics of touch sensor. A?new evaluation tool was proposed in order to promote the objective operation evaluation of a large size touch panel. The SNR was measured by function generator signal as like display noise. The noise of the surface vibration and the noise of external electric device were removed by used the ground. Response of touch sensor was verified by a scanning period and evaluated by oscilloscope. Touch module was measured by sum display reaction time and the capacitance change of the sensor reaction.
