Title: Picture display device
Inventor: SHIGETA KAZUYUKI
IPC: H04N5/66
Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent the picture quality of a display device from being degraded when the device is made to perform multi-level display by applying a PWM (pulse width modulation) converting signal to display elements of binary display. SOLUTION: When the updating frequency of a screen is 60 Hz, one frame period F0 becomes 1/60 Hz. At this time, when the display panel of the device is driven with a color sequentially switching system, it is sufficient to apply picture signals R1, G1, B1 of RGB by ones of every picture signals (3 signals in total) in this one frame period F0, however, since it is needed to perform a high frame rated drive in order to avoid a color breaking phenomenon, it is necessary to apply the picture signals by fours of every picture signals (12 signals in total) in the frame period as shown in the figure. On the other hand, diffusion data N1,... for reducing false outlines are added to respective picture signals R1, G1, B1, however, the diffusion data N1,... are not made equal in one frame period F0 but are changed.  As a result, even when noise based on the diffusion data N1,... appears on the screen, since the noise is switched by high frequency, the noise is not be recognized visually and the degradation of the picture quality is apparently prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a detecting circuit for scanning synchronizing signal which can prevent an erroneous detection of a scanning synchronizing signal due to a stray light and can detect a correct synchronizing signal independent of the optical power of a laser beam. SOLUTION: The circuit is provided with a laser beam detector 12 which can receive a scanned laser beam and a synchronization detecting circuit which outputs a scanning synchronizing signal HSYNC by signal processing of an output Va of a laser beam detector 12.
