In the United Kingdom, there is a legally enforced lighting-up time, defined as from half an hour after sunset to half an hour before sunrise, during which all motor vehicles on unlit public roads (except if parked) must use their headlights.
Spontaneous light emitting device and driving method thereof
A counter 102 counts the accumulated lighting time or the accumulated lighting time and the intensity of lighting of each pixel by a first image signal 101A and stores them in a volatile memory 103 or a nonvolatile memory 104. A correction circuit 105 corrects the first image signal based on the correction data stored previously in a correction data storage section 106 in accordance with the degree of the degradation of each spontaneous light emitting element by the use of the accumulated lighting time or the accumulated lighting time and the intensity of lighting, and produces a second mage signal 101B. By the second image signal 101B, a display unit 107 can provide a uniform screen having no variation in luminance even if the light emitting elements in a part of the pixels are degraded.

ActiveUS20050062951A1Avoid quality lossReduce delaysSemiconductor/solid-state device manufacturingPhotomechanical exposure apparatusLuminous intensityEffect light
An edge exposing apparatus includes a photo detector and a lighting time measuring circuit for detecting a decrease in performance of light source units. The same lighting time measuring circuit has a function to detect a ready state (i.e. stabilization of luminous intensity) of the light source units capable of performing edge exposure. When the lighting time measuring circuit detects a lighting time having reached a preset value, or when the photo detector detects a luminous intensity below a preset value, the light source units are determined to have lowered in performance, and are switched off. The lighting time measuring circuit measures a lighting time from a startup (switch-on) of the light source units, and when the lighting time reaches a preset value, the light source units are determined to have attained the ready state and edge exposure is started with the light source units. When a decrease in performance is detected, one light source unit is started while continuing edge exposure with the other light source unit. When a ready state is detected, the edge exposure with the light source unit is terminated (switch-off), and edge exposure is performed with the light source unit having attained the ready state.
