IPC: H03L7/095
Filed: 2001-10-03
Abstract: PROBLEM TO BE SOLVED: To suppress a wander and a jitter without a phase ripple of output clock by enabling the frequency at look to be maintained even if abnormality such as break, etc., occurs in an input clock. SOLUTION: A fundamental circuit for phase preservation is composed of a phase comparator 1, a low-pass filter 3, a voltage control oscillator 4, and a frequency divider 12. An abnormality detector 10 monitors the pulse width of a phase error signal (c), and judges it to be in abnormal state when it gets over a specified threshold such as the time of break of an input clock, etc. At this time, a controller 11 controls a selector 13 to selectively output a phase error signal (f) stored in a phase error holder 2 to the low-pass filter 3, thus it can keep the lock state where the frequency is stable by suppressing the wander and the jitter.

IPC: G02F1/133
Filed: 2001-10-23
Abstract: PROBLEM TO BE SOLVED: To control brightness of backlight, in which the addition of circuits and power consumption are suppressed. SOLUTION: A timing control part divides the RGB grayscale levels of an image into at least three or more levels (S100). The numbers, contained in the divided levels of respective data extracted from a video of R, G, and B applied from the outside, are counted and compared with each other, on the basis of one video frame (S200, S300, S400). A voltage applied to a backlight drive part is adjusted, in response to the comparison, and the timing control part adjusts the brightness level by units of one video frame. The timing control part increases the brightness of backlight in the case of a screen, in which a high grayscale concentrates locally (or a screen, for which high contrast is demanded), or a screen which has a high grayscaly as a whole (or screen which demands high brightness). Otherwise, the timing control part always maintains brightness to the normal level (S210, S320, S410, S510).
