Touch dimming device and touch dimming method

The invention relates to a touch dimming device and a touch dimming method. The touch dimming device comprises a touch panel and an active color-changing film. The touch panel includes a first electrode and a second electrode to perform touch detection according to a coupling capacitance between the first electrode and the second electrode. The active color-changing film comprises a third electrode and is used for changing the light transmittance of a polymer layer in the active color-changing film according to the voltage difference between the second electrode and the third electrode. Therefore, due to the fact that the touch panel and the active color-changing film share the second electrode, the overall size of the touch dimming device can be reduced. 本揭示内容关于一种触控调光装置及触控调光方法，触控调光装置包含触控面板及主动式变色膜。触控面板包含第一电极及第二电极，以根据第一电极及第二电极之间的耦合电容执行触控侦测。主动式变色膜包含第三电极，且用以根据第二电极及第三电极之间的电压差，改变主动式变色膜中的聚合物层的透光率。据此，由于触控面板及主动式变色膜共用第二电极，故能让触控调光装置的整体体积得以缩减。
