摘要： A projection type display apparatus includes a housing having a first side on which an air intake opening is arranged and a second side on which an air exhaust opening is arranged, a light source for supplying light, and a light valve device which modulates the light output from the light source. A first fan is provided which draws air from the air intake opening into the housing, and a first ventilation path is coupled with the air intake opening so as to lead air flow from the air intake opening toward a lower portion of the light valve. A second ventilation path is formed from the lower portion of the light valve to an upper portion of the light valve, and a second fan is provided which draws out air flowing from the second ventilation path through the air exhaust opening to outside of the housing.

摘要： An electron emission type display apparatus has on a flat plane a matrix layout of multiple light-emitting elements which are connected to cross-points of longitudinal and lateral common electrodes, for sequentially turning on a line of light-emitting elements connected to a common electrode. In such the device, distortion takes place in drive waveform since a low-pass filter (LPF) is formed by a combination of the wiring resistance of the common electrode and the capacitance of a light-emitting element. To avoid such waveform distortion, the width of a light-emitting element driving voltage pulse is caused to be greater than the width of a scan voltage pulse.

摘要： There is provided a clock-recovering filter circuit for use in a clock recovery circuit that generates a recovery clock signal from input data from an external device and a reference clock signal. The filter circuit includes: a pulse-inserting circuit which inserts pulses in a first phase-advancing signal or a first phase-delaying signal, thereby generating a second phase-advancing signal or a second phase-delaying signal; and a frequency-offset detecting circuit which detects frequency-offset data from the second phase-advancing signal and the second phase-delaying signal, the frequency-offset data representing a frequency difference between the recovery clock signal and the reference clock signal. The pulse-inserting circuit inserts pulses in accordance with the frequency-offset data when the first phase-advancing signal or the first phase-delaying signal is not input.

摘要： A display apparatus includes a light source, plural reflecting type light valves having a light incidence/reflection surface which reflects incident light from the light source, and a partition wall which partitions a space in the display apparatus into a cooling air side and a light incidence/reflection surface side. Plural cooling fans which cause air flow to respective ones of the light valves, and a discharge fan which discharges a cooling air inside of the display apparatus through an outlet port are provided. A respective one of the cooling fans flows air to a side which is opposite to the incidence/reflection surface of a respective one of the light valves and a path of the air flow is formed from at least one of the cooling fans to the outlet port in an order of the opposite side of the light valve, the light source and the discharge fan.
