Among them, the through-resistance detection pattern of 200 a and 300 a can be a common common oxide tin film. Different from the prior art, each film of the present invention comprises a plurality of through-resistance detecting patterns 20 0a and 3〇〇a lines. Each of the through-resistance detecting patterns 200a is arranged in parallel; and each of the through-resistance detecting patterns 300a is arranged in parallel; and the through-resistance detecting pattern of the pattern 200a and the through-resistance detecting pattern 3〇〇a The lines are arranged vertically in rows and columns. The Y-axis electric shock 20 0b and the X-axis electric shock 30 0b are respectively placed at the ends of each of the penetration resistance measurement patterns 200a and 3〇〇a lines.

[F點以及g點座標] 5151一9780-PF 9 200915165 如圖所示，因為F點以及G點同時位於穿透電阻偵測 圖樣20 0a以及300a的X5行與γ7列交接處，因此無法單 獨偵測F點以及G點座標。不過這個問題可藉由調整穿透 電阻偵測圖樣200a以及300a的線條寬度即可解決。此 外’本發明儘可能的縮小穿透電阻偵測圖樣2〇〇a以及 3 0 0a線條之行與行以及列與列間的距離，並維持以氧化鋼 錫薄膜當作透明導電薄膜時可允許的隔離範圍中。 本發明提供之觸控面板的垂直結構與習知的電阻式 觸控面板的結構相同。因此可用習知觸控面板之工呈 如：手指、觸控筆、卡片以及釘子等，觸控本發明:觸= 面板。 六自知電阻 觸控面板中使用的辨識電路相同。由於本發日Μ 時，只會加電壓於觸控面板上觸碰點對應的行盘列Ί 相較習知技術更為省時省電。此外1 了減 電源娜，待機電源需要減少，習知的電 := 無法辨識多重觸控，但根據本發明之閑述，不但，幕 別多重觸控的觸控面板h冰、„ Λ 可識 優點。 面板此外_時涵蓋習知技術的所有 堇用以祝明本發明精神之最佳實 用以限定本發明。钰衍土、 Θ知例，非 可未脫離本發明之精神與範症 其進行之等效修改或變 可，而對 圍中。 U更，均應包含於後附之申請專利範[F-point and g-point coordinates] 5151-9780-PF 9 200915165 As shown in the figure, since point F and point G are simultaneously located at the intersection of X5 line and γ7 column of penetration resistance detection patterns 20 0a and 300a, they cannot be separated. Detect the F point and the G point coordinates. However, this problem can be solved by adjusting the line width of the through-resistance detecting patterns 200a and 300a. In addition, the present invention minimizes the distance between the rows and rows and the columns and columns of the through-resistance detection pattern 2〇〇a and 300a, and maintains the use of the tin oxide film as a transparent conductive film. In the isolation range. The vertical structure of the touch panel provided by the present invention is the same as that of the conventional resistive touch panel. Therefore, the conventional touch panel can be used, such as a finger, a stylus, a card, a nail, etc., to touch the present invention: touch = panel. Six self-known resistors The identification circuit used in the touch panel is the same. As this is the day of the day, only the voltage corresponding to the touch point on the touch panel is added. This saves time and power compared to the conventional technology. In addition, the power supply is reduced, the standby power supply needs to be reduced, and the conventional power: = can not recognize the multi-touch, but according to the present invention, not only the multi-touch touch panel h ice, „ Λ 优点 优点The present invention is intended to be illustrative of the present invention.
