    Abstract: Display irregularities in light emitting devices, which develop due to dispersions per pixel in the threshold value of TFTs for supplying electric current to light emitting elements, are obstacles to increasing the image quality of the light emitting devices. An electric potential in which the threshold voltage of a TFT (105) is either added to or subtracted from the electric potential of a reset signal line (110) is stored in capacitor means (108). A voltage, in which the corresponding threshold voltage is added to an image signal, is applied to a gate electrode of a TFT (106). TFTs within a pixel are disposed adjacently, and dispersion in the characteristics of the TFTs does not easily develop. The threshold value of the TFT (105) is thus cancelled, even if the threshold values of the TFTs (106) differ per pixel, and a predetermined drain current can be supplied to an EL element (109).

  • Patent number: 8576259
    Abstract: This application is directed to driving methods for electrophoretic displays. More specifically, the methods are suitable where there is a requirement for a partial update of the images in the display, where a partial update means that less than 10% of the pixels require updating. An essential element of the method is a floating common electrode. This method for partial updating may be used with the prior art driving techniques in order to provide the optimum updating method for different applications.

  • Patent number: 8564515
    Abstract: A gate driver circuit includes a driving section and a wiring section. The wiring section receives a plurality of signals from an external device. The driving section includes a plurality of stages providing a plurality of gate lines with a gate signal. The wiring section includes first and second signal wirings. The first signal wiring is disposed adjacent to a first side of the driving section, where the first side receives the signals from the wiring section. The second signal wiring is disposed adjacent to a portion that is disposed at an outer side of the driving section and the first signal wiring. Therefore, a signal applied to the first signal wiring is prevented from being delayed by the second signal wiring. Furthermore, a distortion of signal applied to the gate driver and a maloperation of the gate driver are prevented.

    Abstract: A pixel circuit having a function of compensating for characteristic variation of an electro-optical element and threshold voltage variation of a transistor is formed from a reduced number of component elements. An input signal is sampled from a signal line so as to be held in a holding capacitor. The threshold voltage of the drive transistor is imparted to the holding capacitor in order to cancel an influence of the threshold voltage.

    Abstract: An autostereoscopic display apparatus includes: a display panel displaying an image by using light beams from color pixels; and a parallax division part disposed to face the display panel. The parallax division part divides a color pixel region of the display panel into a right-eye color pixel region RG visible to the right eye but invisible to the left eye and a left-eye color pixel region LG visible to the left eye but invisible to the right eye, so that different images are visible respectively from the right eye and the left eye. Color pixels BG outputting no light beams are arranged in a boundary between the right-eye color pixel region RG and the left-eye color pixel region LG. An arrangement direction of the color pixels BG outputting no light beams is inclined.
