Passage and blocking, and the use of color filters to achieve the function of color display. Among them, the touch module that senses the user's touch position will be placed in the liquid crystal display structure. When the user's finger touches the display panel, the touch module will read the row and column positions touched by the finger. In this way, the signal of the finger position is transmitted, so that the display panel has both display and touch functions.
如上所述,由於目前觸控式顯示面板的製程方式,係將觸控模組設置於液晶顯示結構中,然而,因製程與光罩之關係,此方式會導致設置電路的複雜度提高,並且增加電路的設置成本。再者,液晶顯示結構也會有良率高低的問題,若液晶顯示結構被檢測為損壞而無法使用時,位於液晶顯示結構中的觸控模組即便仍為良品,勢必也只能一併淘汰丟棄,進而增加額外的成本負擔。As mentioned above, due to the current manufacturing method of touch display panels, the touch module is installed in the liquid crystal display structure. However, due to the relationship between the manufacturing process and the photomask, this method will increase the complexity of the circuit configuration, and Increases the setup cost of the circuit. Furthermore, the LCD structure will also have yield issues. If the LCD structure is detected to be damaged and cannot be used, the touch module located in the LCD structure will inevitably be eliminated even if it is still a good product. discarded, thereby adding additional cost burden.
