摘要:
A television receiver having a liquid crystal display device includes a receiver having a electromagnetically shielded case and a receiving circuit provided in the shielded case and electrically connected to an antenna for producing audio signals and video signals. A liquid crystal display panel of the liquid crystal display device is electromagnetically shielded by a transparent and conductive shielding film for shielding the liquid crystal display panel.

A television receiver includes a baseband 90.degree. phase shifter, an adder, and a phase equalizer. The baseband 90.degree. phase shifter obtains in-phase video signals from the video signals of the I and Q signal blocks. The adder voltage-adds the in-phase video signals together. The phase equalizer corrects phase distortion of an output signal from the adder. The 90.degree. phase shifter has an operating frequency band including at least a received channel and a lower adjacent channel. A video signal is extracted from the phase equalizer.

A television receiver has a receiving circuit for producing audio signals and video signals, a liquid crystal display panel, and a driving circuit responsive to the video signals for driving the liquid crystal display panel. The receiving circuit and driving circuit include elements provided on an SOS substrate.
摘要:
A multi-layer integrated circuit having through-hole inter-layer connections includes an integrally formed liquid crystal display panel, and performs all receiving, amplifying and video display functions of a TV receiver when connected to an antenna. Shield layers are incorporated to prevent transmission of interference from a display drive section of the integrated circuit to the antenna or the input stage of an I.F. amplifier section, and to prevent interference between the local oscillator of a tuner section and the I.F. amplifier.
