  • Patent number: 10497324
    Abstract: An illuminated display device with a base member representing an eye and having a primary cavity therein, usually existing as a pair of devices to represent two eyes. Thin walls within the primary cavity divide it into multiple chambers, wherein each chamber has a unique shape and volume that represents a view of a unique emotive response in an eye. Illumination devices are placed in each unique thin-walled chamber shape to emit light in a pattern from the chamber volume through a top opening of the cavity. Lighting all illumination devices equally imitates an open eye, while illuminating the volume of one or more unique chamber shapes at OFF or lesser brightness than the volume in other chambers creates a negative space, giving the illusion that the eye has changed shape to equal the shape in the brightly lit chambers only. The device can thus imitate the changing shapes in an eye shown when expressing emotion and the device is capable of exhibiting eight or more distinct emotive responses.

    Abstract: Pixel electrodes (17a and 17b) are provided in a pixel (101), and the pixel (101) is associated with a data signal line (15x), scanning signal lines (16a and 16b), and transistors (12a and 12b). One pixel electrode (17a) is connected to the data signal line (15x) via the transistor (12a). The other pixel electrode (17b) is connected to the pixel electrode (17a) via a capacitor (C101) and is connected to the data signal line (15x) via the transistor (12b). Storage capacitance (Cha and Chb) is formed between the pixel electrodes (17a and 17b) of the pixel (101) and a scanning signal line (16d) associated with a pixel (100). Thus, a configuration of a liquid crystal display device of a capacitively coupled pixel division mode is proposed in which a decline in display quality caused by image sticking of a sub-pixel is less likely to occur.
