ABSTRACT:
An image-sensing display panel comprises an image display, including a display panel (30) and lighting means, and an image sensor (40). By using a reflective LCD display panel (30) and arranging the light guide (50) of the lighting means in front of the image sensor (40), the device has a high light efficiency, and lens means (110, 120, 130) can be integrated in components (40, 50, 100) of the device, which results in a compact construction of the device.
