The invention relates to a vehicle-mounted touch display device. The device comprises a capacitive touch screen and a display screen; the capacitive touch screen is arranged on the outer side of the display screen and attached to the display screen. The capacitive touch screen comprises a glass substrate and a touch circuit layer arranged on the inner side of the glass substrate. The device is characterized in that the capacitive touch screen further comprises an extinction layer, an extinction layer is clamped between the touch circuit layer and the glass substrate, and the extinction layer is a black or dark light absorption film layer with the average light transmittance less than 30%. According to the vehicle-mounted touch display device, the reflected light of the touch circuit layercan be greatly eliminated, the screen effect close to pure black is achieved, the manufacturing process is simple, and the manufacturing difficulty of the capacitive touch screen is greatly reduced.
本发明涉及一种车载触控显示装置,包括电容触摸屏和显示屏,电容触摸屏设置在显示屏的外侧并且相互贴合,电容触摸屏包括玻璃基板以及设置在其内侧的触控电路层,其特征在于:所述电容触摸屏还包括消光层,消光层夹置在所述触控电路层与所述玻璃基板之间,消光层为平均光透过率小于30%的黑色或深色吸光膜层。这种车载触控显示装置不仅能够大幅度地消除触控电路层的反射光,达到接近纯黑的屏幕效果,而且制作工艺简单,大幅度降低电容触摸屏制造的难度。
