DISPLAY DEVICE WITH MEMORY FUNCTION, TERMINAL DEVICE, AND DRIVING METHOD THEREOF

摘要

An image update determining unit compares a previously set temperature with a temperature estimated by a temperature increase estimating unit, and determines whether or not an image update operation is executable, and an image update interval is appropriately set according to the estimated temperature by performing image update on an image to be displayed next when the image update determining unit determines the image update operation to be executable but not performing image update when the image update determining unit determines the image update operation to be non-executable.

主权项

1. A display device with a memory function, comprising:
a first substrate on which a plurality of pixels each of which includes a switching element and a pixel electrode are arranged in a matrix form, and a source line for applying a predetermined signal to the switching element and a scanning line for controlling the switching element are arranged; a second substrate on which an opposite electrode is formed; a display layer that is interposed between the first substrate and the second substrate and configured with an display element with a memory function; a driver that outputs a predetermined signal to the source line; a temperature acquiring unit that acquires a temperature of the driver; an image load value calculating unit that calculates an image load value based on image data to be displayed next; an temperature increase estimating unit that estimates the temperature of the driver after an image update operation of an image to be displayed next according to a temperature acquired by the temperature acquiring unit and the calculated image load value before the image update operation; an image update determining unit that compares a previously set temperature with the temperature estimated by the temperature increase estimating unit, and determines whether or not the image update operation is executable; and an image display control unit that executes the image update operation, wherein the image display control unit executes image update on the image to be displayed next when the image update determining unit determines the image update operation to be executable.
