Title: Color irregularity correction device
Inventor: SERITA HIROAKI
IPC: G02F1/133
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To suppress brightness irregularities caused by liquid crystal layer thickness irregularities (gap irregularities) of a liquid crystal panel, and to suppress color irregularities by correcting so as to obtain a similar characteristic, especially even if generation forms of the brightness irregularities are different for every liquid crystal panel. SOLUTION: A correction circuit 50 for generating a correction signal for correcting brightness irregularities caused by liquid crystal layer thickness irregularities of a liquid crystal panel, is installed. The correction circuit 50 generates a correction signal obtained by modulating a signal changing gently so that the amplitude becomes smaller toward the center in the horizontal direction of the liquid crystal panel and that the amplitude becomes smaller toward the center in the vertical direction by viewing the signal in the vertical direction, with a signal obtained by removing a high-pass component from an input image signal. The correction signal from the correction circuit 50 is added to the input image signal by an addition means 51, and then supplied to a liquid crystal panel part 10 after executing a signal processing for alternating-current driving or the like.  By applying a formation in which the correction signal is superimposed on the input image signal of the liquid crystal panel in this way, brightness irregularities can be corrected. Especially, by correcting brightness irregularities of each three-board type liquid crystal panel so as to obtain the same brightness characteristic, generation of color irregularities can be suppressed.

Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To stably cool while sufficiently drawing cooling power by controlling a suction side superheat degree and an outlet side supercooling degree in response to refrigerant amounts in a condenser and an evaporator judged based on an outlet side refrigerant supercooling degree of the condenser and a suction side refrigerant superheat degree of a compressor. SOLUTION: Refrigerant amounts in a condenser 2 and an evaporator 4 are judged based on an outlet side refrigerant supercooling degree of the condenser 2 and a suction side refrigerant superheat degree of a compressor 1. As a result, when it is judged that the refrigerant amount in any of the condenser 2 and the evaporator 4 is less than a reference refrigerant amount, a valve travel of an expansion valve 3 is controlled so that the suction side superheat degree becomes a target superheat degree. When it is judged that the amount in the condenser 2 or the evaporator 4 is more than the reference amount, the travel of the valve 3 is controlled so that the outlet side supercooling degree becomes a target supercooling degree. The judging operation is executed by a controller 29.  Thus, the cooling operation can be stably conducted while sufficiently putting a sealed refrigerant amount into practical use.
