Display system comprising controller which process data
First Claim
1. A display system comprising:
- a host device;
a display controller; and
a display panel,wherein the host device is configured to send first image data to the display controller,wherein the first image data is image data for one pixel, andwherein the display controller is configured to perform;
processing of the first image data to generate second image data,classification of the first image data and determine whether the first data being color data based on a result of the classification,processing of the second image data to generate third image data, wherein the processing of the second image data being different between the second image data being color data or not being color data,processing of the third image data to generate fourth image data, andtransmission of the fourth image data to the display panel.

Abstract
A display system includes a host device, a display controller, and a display panel. The display panel includes a pixel array including a plurality of subpixels each including a light-emitting display element and a reflective display element. The host device sends image data DT0 to the display controller. The display controller has the following functions: color classification of the image data DT0; generation of attribute data based on the classification result; generation of image data DT1 from the image data DT0; generation of two kinds of image data DT2_e and DT2_r through image processing of the image data DT1 in accordance with the attribute data; generation of image data DT3_e from the image data DT2_e; and generation of image data DT3_r from the image data DT2_r. The image data DT3_e is displayed by the light-emitting display element, and the image data DT3_r is displayed by the reflective display element.

15. A display system comprising:
-
a display controller; and a display panel including a pixel array and a peripheral circuit, the pixel array including a pixel, wherein the pixel includes a plurality of first subpixels each including a reflective display element and a plurality of second subpixels each including a light-emitting display element, wherein the display controller is configured to process first data sent from an outside to generate second data and third data, process the second data to generate fourth data, process the third data to generate fifth data, and send the fourth data and the fifth data to the display panel, wherein the peripheral circuit is configured to write the fourth data and the fifth data to the pixel, wherein the fourth data is displayed by the plurality of first subpixels, wherein the fifth data is displayed by the plurality of second subpixels, wherein the display controller is configured to determine whether the first data is color data, and wherein when the first data is determined as the color data, the display controller makes black display data as the second data, and makes a copy of the first data as the third data. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
