Display system, control system, and display method

摘要

To provide a display device which can reduce driving frequency of a controller and a driver for inputting a signal to the display device and increase brightness of a screen without increasing the driving frequency. The display device includes: a display screen having a plurality of pixels provided by corresponding to intersection points between scan lines and data lines; a scan line drive circuit which drives the scan lines; a data line drive circuit which drives the data lines; and a display device body having an image display control device which operates the drive circuit so as to sequentially and repeatedly display two or more types of images. The image display control device causes the scan line drive circuit to simultaneously select two or more scan lines for at least one type of image among the two or more types of images sequentially displayed.

1. A display system which repeatedly displays a frame in which two or more types of images are sequentially displayed on a display screen within one period of the frame by writing image data while scanning pixels on the display screen, the display system comprising:
a controller which simultaneously selects two or more pixels of the display screen for a specific image among the two or more types of images, writes a same image data to the two or more selected pixels to display the specific image with a simultaneous writing method, individually selects the pixels of the display screen for images other than the specific image, and individually writes an image data to the individually selected pixels to display the images other than the specific image with a simultaneous writing method so as to control display of those images, wherein the controller has a function of executing the display with the simultaneous writing method and the display with the individual writing method sequentially and repeatedly, and reducing the writing period of the specific image within one period of the frame with the simultaneous writing method, and further, the controller has: a function of decreasing the writing frequency of the images sequentially displayed by allotting an extra time generated by making a writing period shorter, to the writing periods of the images sequentially displayed on the display screen within one frame period, or a function of increasing the brightness of the images without increasing the writing frequency of the images sequentially displayed by allotting the extra time to a period for determining brightness of the images sequentially displayed on the display screen within one frame period, or a function of decreasing the writing frequency of the images sequentially displayed and increasing the brightness of the images by allotting the extra time to both of the writing period and the period for determining the brightness of the images.
