在一些實施例中,第一控制線為至少二條的情況下,前述實施例僅呈現第2B圖中AA’線的縱剖面圖,實際上整個觸控裝置的走線配置,可為前述所有實施例之排列組合,換言之,走線的配置依照電路上電阻電容振盪的負載及面板之開口率改變,依據需求具有不同的設計方式。In some embodiments, in the case where there are at least two first control lines, the above-mentioned embodiments only show the longitudinal cross-sectional view of line AA' in FIG. 2B. In fact, the wiring configuration of the entire touch device can be implemented in all the above-mentioned implementations. The arrangement and combination of the example, in other words, the configuration of the traces is changed according to the load of the resistance-capacitance oscillation on the circuit and the aperture ratio of the panel, and there are different design methods according to the needs.
在一些實施例中,根據多工器電路在觸控裝置中的位置,走線改變配置後,電阻電容也會隨著變化,列出多工器電路與積體電路之相對位置的電阻電容值如下:
在一些實施例中,請參閱表一,在第一控制線為至少二條的情況下,首先,多工器電路與積體電路位在同側與對側時的電阻值非常相近,接著,多工器電路與積體電路位在同側與對側時的電容相差接近兩倍,隨後,因阻抗及電阻電容振盪的公式與電容成反比,在電阻相近的情況下,電容越大,阻抗及電阻電容的振盪越小。In some embodiments, please refer to Table 1. In the case where there are at least two first control lines, firstly, the resistance values of the multiplexer circuit and the integrated circuit are very similar when they are located on the same side and the opposite side. The difference between the capacitance of the industrial circuit and the integrated circuit when they are on the same side and the opposite side is nearly twice. Then, because the formula of impedance and resistance-capacitance oscillation is inversely proportional to the capacitance, when the resistance is similar, the larger the capacitance, the higher the impedance and the higher the resistance. Resistor-capacitor oscillation is smaller.
依據前述實施例,本案提供了一種觸控裝置,藉由多工器電路移至積體電路的對側,即為面板之中可操作區域(Active area)的一側,有效降低可操作區域另一側的結構空間,再因應多工器電路的改變,本案實施例提供了多種走線配置,這些走線配置能夠有效降低電阻電容振盪時的負載,以及有效提高面板之開口率。According to the aforementioned embodiments, the present application provides a touch device, which is moved to the opposite side of the integrated circuit by the multiplexer circuit, that is, the side of the active area in the panel, effectively reducing the other side of the active area. Due to the structural space on one side, and in response to the change of the multiplexer circuit, the embodiment of the present case provides a variety of wiring configurations, which can effectively reduce the load when the resistor and capacitor oscillate, and effectively improve the aperture ratio of the panel.
