摘要:
A picture transmission system is provided that provides a solution to drops in picture quality. A multiplexing unit (11) multiplexes N pictures in display order to generate a multiplexed picture. A transmission unit (12) transmits the multiplexed picture. A frame memory (23) delays pictures in the multiplexed picture that is received by a reception unit (21) by a one-frame interval of the pictures (one subframe interval) to generate reference pictures. With each reception of a picture in the multiplexed picture by the reception unit (21), an OD arithmetic unit (25) converts the picture element value of the picture (object picture) based on the reference picture to generate an OverDrive picture. A time-division display apparatus (3) displays the OverDrive pictures.

A display system includes display terminals (1-1-1-4) that display pictures, a display control apparatus (3) that controls the display of pictures on the display terminals (1-1-1-4), and optical shutters (2-1-2-4) that are provided corresponding to each of the display terminals (1-1-1-4) and that enter a state of transmitting incident light in intervals in which private pictures are displayed on corresponding terminals and enter a state of blocking incident light in other intervals. The display control apparatus (3) controls the display terminals (1-1-1-4) such that private pictures are not simultaneously displayed on display terminals (1-1-1-4).

Disclosed is a liquid crystal shutter having two superimposed liquid crystal layers in which no leakage of light occurs. In a liquid crystal shutter in which oriented films (11) of a pair of substrates of each liquid crystal device (8a, 8b) are oriented in mutually intersecting directions, and are all vertically oriented films or horizontally oriented films, and if the oriented films are horizontally oriented films, the liquid crystal materials have a positive dielectric constant isotropy, and if the oriented films are vertically oriented films, the liquid crystal materials have a negative dielectric constant isotropy, the twist directions (13) of the liquid crystal materials en- closed in the adjacent liquid crystal devices (8a, 8b) are opposite to each other to thereby prevent the leakage of light.

An output circuit, a digital/analog conversion circuit and a display apparatus can reduce the number of required input voltages and the number of transistors to save the necessary area. The output circuit and the digital/analog conversion circuit comprise a selection circuit for receiving as input a plurality of (m) reference voltages having mutually different respective voltage values, selecting two of the voltages according to a selection signal and outputting them and an amplifier circuit for receiving as input the voltages output from the selection circuit at two input terminals T1, T2 and outputting the voltage obtained by interpolating the voltage difference of the two input terminal voltages V(T1), V(T2) to a predetermined ratio. It may alternatively be so arranged that the selection circuit sequentially outputs the selected two voltages and the amplifier circuit sequentially receives as two input the two voltages and outputs the output voltage obtained by interpolation.

A multilevel voltage generating circuit includes first and second input nodes provided on a first resistance element and supplied with first and second reference voltages. A current substantially flows in a first specific area for a line between the first and second input nodes based on a difference between the first and second reference voltages. A first group of output nodes are provided for the first resistance element to output a portion of a plurality of level voltages. A first one of the first group of output nodes for one of the plurality of level voltages which is closest to the first reference voltage is provided outside the first specific area. The first output node, the first input node, and the second input node, are arranged on a line on the first resistance element in this order.
