Title: Display device
Inventor: ASANO MICHIO
IPC: G09F13/30
Filed: 1994-07-14
Abstract: PURPOSE:To provide the display device which can display an image by utilizing an afterimage and also prevents the luminance from being uneven. CONSTITUTION:An array light source 1 changes in the illumination/ nonillumination pattern of its light emitting diodes 10n at time intervals from time t1 to time t26. At this time, when the eyes of the driver of a following vehicle move from, for example, an instrument board etc., to the array light source 1 as the high mount taillights of a precedent vehicle, the array light source 1 moves relatively in the visual field of the driver of the following vehicle from the top to the bottom and the blinking operation of the array light source 1 is seen to the driver of the following vehicle as a figure 5 of a black inverted triangle on a red ground through an afterimage phenomenon. When the time progress of one light emitting diode 10n is traced, any light emitting diode 10n turns off about five times from the time t1 to the time t26. Namely, the light emitting diodes 10n are so controlled that they are equal in illumination time. Consequently, any light emitting diode 10n is brought under blinking control so that the duty ratio is nearly equal, so when the array light source 1 is gazed, no luminance unevenness is generated.
