FIELD SEQUENTIAL IMAGE DISPLAY DEVICE

摘要

There has been room for improvement in terms of increasing the life of display elements which have occurrences of irreversible bright point defects and black point defects and shortened lives of display elements when DMDs, which are reflective display devices, are used in high temperature environments such as being installed in vehicles. In the present invention, a display control means displays a display image in display elements. An illumination control means drives various illumination means in each subframe into which a frame of the display image is temporally divided, by a field sequential system. The frame is provided with a display period in which the display image is displayed in the display elements by the display control means normally driving a plurality of pixels and the illumination control means driving the illumination means and a non-display period in which the display image is not displayed in the display elements by the display control means engaging in non-display period drive of the plurality of pixels and the illumination control means turning off the illumination means.

主权项

1. A field sequential image display apparatus, comprising:
a display element, having a plurality of pixels, which displays a display image; display control means which controls the plurality of pixels; first illumination means which illuminates the display element with a first emission color; second illumination means which illuminates the display element with a second emission color; illumination control means which drives the first illumination means and second illumination means using a field sequential method for each of sub-frames into which a frame of the display image is time divided; and a control unit which inputs display image data of the display image from the exterior, and based on the display image data, controls the display control means and illumination control means, the apparatus being characterized in that the frame includes: a display period in which the display control means causes a normal drive of the plurality of pixels, and the illumination control means drives the first illumination means and second illumination means, thereby causing the display element to display the display image; and a non-display period in which the display control means causes a non-display period drive of the plurality of pixels, and the illumination control means turns off the first illumination means and second illumination means, thereby not causing the display element to display the display image.
