摘要： A display apparatus is constituted to have a multiplicity of pixels each divided into at least two sub-pixels having mutually different areas including a larger sub-pixel having a larger area and a smaller sub-pixel having a smaller area. Each sub-pixel is provided with a transparent electrode and a low-resistivity conductor connected to the transparent electrode, and the low-resistivity conductor for the larger sub-pixel is set to have a lower resistance than the low-resistivity conductor for the smaller sub-pixel. As a result, a pixel switching characteristic can be uniformized over an entire picture area of the display apparatus regardless of different areas (loads) of the sub-pixels and without using different performances of drivers.

摘要： A laser beam with a wavelength .lambda. emitted from a laser beam source is split into first and second pump beams and a probe beam. The first and second pump beams are incident on light incident surfaces of a photo-nonlinear medium from opposing directions on the same optical path. The probe beam is incident on the light incident surface forming an angle with the first pump beam to generate interference fringes in the normal direction of the light incident surface and to form a refractive index grating. A phase conjugate wave is emitted in the reverse direction to an incident optical path of the probe beam by means of irradiating the second pump beam on the refractive index grating. A direct -current electric field is applied on a pair of external electrodes to be coincident to the wave vector of the interference fringes, where by providing a frequency modulation to the first pump beam using a piezoelectric oscillator, a moving speed "v" of the interference fringes is determined when light intensity of the phase conjugate wave is maximized. A forming time .tau. of the refractive index grating can thus be obtained. An accurate and rapid measurement can generally be obtained for the forming time of the refractive index grating of the photononlinear medium formed of photorefractive crystal including a cubic system such as BSO.

摘要： The motion picture quality of liquid crystal display apparatus is improved by placing a non-display period depending on the responsiveness of the liquid crystal and a backlight source. For this purpose, a sub-period is set, within one frame period, for displaying a luminance corresponding to prescribed picture data so as to provide a time integral of luminance corresponding to a maximum luminance not exceeding a certain threshold, and another sub-period for displaying a lower luminance is placed in the same one frame period.

摘要： A liquid crystal device of the active matrix-type having two-dimensionally arranged pixels along rows and columns is driven frame by frame. In each frame operation, a scanning selection period (TG) for each selected row is divided into a first period (t1) and a second period (t2). In t1 of a current frame (TF2), a reset pulse is applied to a pixel concerned, and the reset pulse is set to have an absolute value of voltage identical to and a polarity opposite to those of a writing pulse voltage applied to the pixel in the previous frame (TF1). Then, in t2 of the current frame (TF2), the pixel is supplied with a writing pulse depending on a prescribed display state of the pixel for the current frame. As a result, the reset period is shortened to favor a high-speed display and a higher resolution display.

The liquid crystal apparatus is effective for suppressing a change in drive waveform frequency depending on a display pattern to suppress the occurrence of crosstalk thereby.
