The LCD module according to the present disclosure includes a liquid crystal cell and a mold frame accommodating the liquid crystal cell. The mold frame includes a support supporting the liquid crystal cell in a thickness direction of the liquid crystal cell and a guide for limiting movement of the liquid crystal cell in a planar direction of the liquid crystal cell. The guide includes a corner-part guide disposed to face a corner part on the corner part of at least one side of the liquid crystal cell, and an inner-part guide facing an inner part being a part of the side other than the corner part, and being adjacent to the corner-part guide with distance. A gap between the liquid crystal cell and the corner-part guide is larger than a gap between the liquid crystal cell and the inner-part guide.

When a main television is turned on, a power source A, a power source B, and a power source C operate. When the main television is turned off (stand-by state), the power source A and the power source B operate, if the sub-television is turned on, and only the power source A operates, if the sub-TV is turned off. Therefore, even when the main television is turned off, as long as the sub-television is turned on, a broadcast reception process and a wireless video transmission to the sub-TV are performed. If both the main television and sub-television are turned off, then electric power supplies to circuits for the broadcast reception processes are stopped, and as a result, electric power consumption is saved.

Broadcast receiving system

A transmitter includes: frequency conversion means for collectively frequency-converting terrestrial digital TV broadcast signals inputted such that the frequency of terrestrial digital TV broadcast signals of a viewing desired channel inputted by viewing desired channel input means, among the terrestrial digital TV broadcast signals inputted, are converted to a frequency of a specific unused channel of a predetermined VHF band; filter means for extracting only TV broadcast signals of the specific unused channel of the predetermined VHF band among the TV broadcast signals obtained by the frequency conversion means; and transmission means for amplifying and wirelessly transmitting the TV broadcast signals extracted by the filter means.

A spread spectrum communictdion system includes a transmitter and a receiver, and an on-off keying signal is inputted to the transmitter. A carrier signal is modulated by the on-off keying signal, and a spread spectrum signal is produced by multiplying a modulated signal by a first PN code which is repetition of 3-bit data. The spread spectrum signal is transmitted through a transmission antenna. In the receiver, a second PN code which is repetition of 4-bit data larger than the first PN code by 1 bit is generated. Therefore, a phase of the second PN code becomes coincident with a phase of the first PN code every 12 bits. Then, a spread spectrum demodulation is performed by multiplying a received spread spectrum signal by the second PN code to reproduce the carrier signal being modulated by the on-off keying signal. The on-off keying signal is restored by envelope-detecting a reproduced carrier signal.
