摘要:
One picture element of a liquid crystal panel is divided into a region I where a cell gap is set to 4 μm and a region II where a transparent insulating film is formed and a cell gap is set to 2 μm. In the region I, there occurs a phenomenon (overshoot) that, when a voltage is applied, luminance becomes high immediately before an alignment of liquid crystal molecules becomes stable, and in the region II, no overshoot occurs. Response characteristics of an entire picture element are those obtained by synthesizing the response characteristics in these regions. Parameters such as an area ratio of the regions I and II, and cell gaps are set so that a maximum luminance value is not greater than 110% of the luminance at a stable time.

The liquid crystal display has a TFT substrate and an opposite substrate, which are provided opposite to the surface thereof and a liquid crystal layer, which is sealed between the both substrates. A pixel range, which is defined by a gate bus line and a drain bus line and is disposed on the TFT substrate, has a sub-pixel A to which a gradation voltage for driving the liquid crystal layer is applied, and a sub-pixel. B which is formed separated from the sub-pixel A and to which a voltage lower than the gradation voltage is applied. On the opposite substrate, linear protrusions are formed so as to regulate the direction of alignment of a liquid crystal molecular of the liquid crystal layer. An arrangement interval w1 (=w1a) of the linear protrusion within the sub-pixel A is formed so as to be shorter than an arrangement interval w2 (=(w2a+w2b)/2) of each of the linear protrusions within the sub-pixel B.

In driving a liquid crystal display device having an alignment regulating structure for regulating liquid crystal, when the display state of the pixel is to be changed from a dark display to a bright display, a difference between the magnitude of a voltage Vd4 applied to the liquid crystal of the pixel at the beginning of the first frame and the magnitude of a voltage Vd3 applied to the liquid crystal of the pixel in the second frame or a subsequent frame, is set to be greater than a voltage Vod that decreases in the first frame due to an increase in the liquid crystal capacitance of the pixel.

To realize a high-quality flat-face type of color cathode ray tube by combining a tint panel with a pressed mask, the outer surface of the panel of the color cathode ray tube is made nearly flat and the inner surface of the panel is curved in a concave shape, and the long-length direction pitch of slots formed in an aperture region 2 of a pressed mask 1 to be disposed close to the inner surface and the connection-direction width of each of bridges which connect the slots are made different between a central portion (A) and a peripheral portion (B) in the apertured region 2 of the pressed mask 1, whereby the ratio of bridges per unit area is made larger in the central portion (A) than in the peripheral portion (B) or the opening rate of slots per unit area is made larger in the peripheral portion (B) than in the central portion (A). According to this construction, the mechanical strength of the central portion (A) of the pressed mask becomes large, whereby it is possible to restrain the occurrence of undesired deformation of the pressed mask 1 due to the increase of the radius of curvature of the central portion (A) and it is possible to uniformize brightness over the entire screen.

A Braun tube for use in a TV receiver or the like, in which its screen does not need high resolution, but the brightness of the screen is important. The Braun tube has a panel with a flat outer surface, an electron gun arranged in an in-line manner and a phosphor screen whose phosphors are arranged in a delta pattern, and the horizontal pitch of a shadow mask can be varied in the direction of the Y-axis. The mechanical strength of the shadow mask is improved by making the curvature of the shadow mask larger than the curvature of the inner surface of the panel in the direction of the vertical axis of the screen.
摘要:
In a tire air pressure warning device, an outside impact such as hydraulic brake pressure is intentionally applied in a pulsating way to a tire when the vehicle substantially stops so as to exert vibration (rotation variation) of the tire axle. Through data processes in analyzing signals of wheel speed sensors that reflect the rotation variation of the tire axle, tire air pressure is estimated for informing to a driver abnormal tire air pressure.
