  • Publication number: 20120223908
    Abstract: A display device (10) according to the present invention includes a display panel (1) and a transparent member (2). In the display device (10), a transparent resin sheet (3) to bond the display panel (1) and the transparent member (2) is arranged between the display panel (1) and the transparent member (2); and the display panel (1) and the transparent member (2) are unified in a shrinkable case (4) made of a heat shrink material. Furthermore, the shrinkable case (4) has a light blocking property. Furthermore, a plurality of shrinkable cases (4) unify the display panel (1) and the transparent member (2). Furthermore, the transparent member (2) is a touch panel.

  • Patent number: 7414607
    Abstract: In a structure in which a plurality of signals related to each other are supplied to a driving circuit in such a manner that at least one of the signals is supplied also to the other circuit, the present invention prevents change of phase relation between the plural signals due to difference in wiring load, without directly processing the signals with higher power consumption. The first and second clock signals SCK1 and SCK2 are supplied to the first data signal line driving circuit SD1, while the first clock signal SCK1 is also supplied to the second data signal line driving circuit SD2 in parallel. The wirings 1 and 2 for the respective signals are adjusted to have equal wiring load with a dummy wiring 2 provided in the wiring 2, for solving uneven wiring load caused by difference of leading manner, the dummy wiring 2 constituting an additional capacitor section 7, together with a liquid crystal layer and a counter electrode.

  • Patent number: 7289097
    Abstract: The subject invention discloses a scanning direction control circuit, which includes a bidirectional shift register in which shifting direction is switched in accordance with a switching signal L/R, which is step-upped by a level shifter when having lower amplitude than the driving voltage. The scanning direction control circuit includes a latch circuit between the level shifter and the bidirectional shift register, and a control circuit causes the latch circuit to carry out latching operation after shifting operation of flip-flops constituting the bidirectional shift register is completed in response to output signals of the flip-flops. The control circuit brings the level shifter into active state in a period before, at and after the latching timing, and brings the level shifter into inactive state in the remaining period. With this arrangement, the switching signal L/R can be supplied at a predetermined timing regardless of external input timing thereof, with low power consumption.

  • Patent number: 6996203
    Abstract: The present invention includes: a shift register section, including multiple-stage flip-flops operating in synchronism with a clock signal, for switching a shift direction in accordance with an externally supplied direction instruct signal; a waveform change section for changing in waveform a signal output of one of the flip-flops which is in a first predetermined stage; and an inspection signal switching section for switching, in accordance with the direction instruct signal, an output between the signal output which has been changed in waveform in the waveform change section and a signal output of one of the flip-flops which is in a second predetermined stage.
