Operating Principle & Structure
The 4-wire resistive touch panel is composed of two layers of conductive materials (Indium Tin Oxide, ITO), which are usually composed of conductive film (ITO film) and conductive glass (ITO glass), these two layers are divided by insulating Spacer Dots.
After the circuit passes through the upper and lower layers to contact each other, an analog voltage signal will be generated, which is the output of the circuit, converting into a digital signal by the controller, then the computer calculates the correct position of the touch. For 4-wire resistive touch panel, X-axis and Y-axis are made separately on the film and the glass, and separates the wiring in the action area. At the same time, a fixed voltage is set to become a uniform electric field, and the difference in voltage value will be converted into an accurate coordinate position.

客製化增強型產品 (Optional)
為達到觸控面板產品高性能的要求，我們的四線電阻產品可以採用以下增強技術來生產，以滿足高端市場的需求。
輕觸技術
低至15g做動力，可以讓使用者擁有接近投射式電容的操作體驗，並減少因為用力按壓而加速ITO塗層的磨耗，進而讓產品的壽命更佳。
寬溫技術
對於低溫-30℃~高溫80℃的極嚴苛環境，能有效控制外觀的變異性並保持產品正常的運作，提供穩定無虞的高性能產品。
高觸擊次數
對於點擊壽命有要求的應用需求，可以提供最多達3500萬次手指點擊次數(同一個點)，並通過嚴謹的點擊測試，確保產品的耐受度。可大幅延長客戶端產品使用壽命。
EMI防護
對於高端市場的需求，如軍規的應用要求，提供 各種EMI防護的解決方案。
耐UV光照射
對於戶外應用需求，長期曝曬在陽光UV紫外光的環境，潛在UV破壞觸控面板表層及鍍膜的風險，進而影響到外觀或功能的疑慮，提供耐UV的設計，有效降低UV照射的問題。
防爆型設計
因為安全性的要求，提供防爆型設計的產品。觸控面板的玻璃基材在碎裂時需符合防爆的規範：當遭受撞擊時，以確防玻璃發生破裂時的碎片不會飛濺出來傷害到人。
加熱型設計
對於低緯度寒冷地區，產品的使用經常於低溫的環境，導致性能或信賴度不佳，提供加熱型設計的產品，能有效改善低溫環境所造成產品的問題，讓產品能正常的運作。
由於特殊光學要求的應用，提供以下解決方案，達到視覺的清晰，減少反射與提高穿透率
