Abstract

A novel semiconductor device or display system is provided. The display system includes a correction circuit having a function of correcting an image signal by utilizing artificial intelligence. Specifically, learning by an artificial neural network enables the correction circuit to correct an image signal so as to alleviate the image discontinuity. Then, by making an inference (recognition) utilizing the artificial neural network which has finished the learning, the image signal is corrected and compensation for the image discontinuity can be made. In this manner, the junction can be inconspicuous on the displayed image, improving the quality of a high-resolution image.

Claims (13)

1. A display system comprising:

a display device comprising a first display region and a second display region, each of the first display region and the second display region comprising a plurality of pixels and being supplied with an image signal;

a correction circuit comprising a neural network; and

an arithmetic processing device configured to perform neural network learning and to supply a weight coefficient obtained by the learning to the correction circuit,

wherein the neural network is configured to correct the image signal for the pixel in a vicinity of a boundary between the first display region and the second display region, and

wherein the learning is performed by updating the weight coefficient in accordance with a difference between the image signal and a signal corresponding to an image displayed on the display device on a pixel row basis.

2. The display system according to claim 1 ,

wherein the neural network comprises an autoencoder, and

wherein the autoencoder comprises a decoder and an encoder.

3. The display system according to claim 1 , wherein each of the plurality of pixels comprises a transistor comprising amorphous silicon in a channel formation region.

4. The display system according to claim 1 , wherein each of the plurality of pixels comprises a transistor comprising a metal oxide in a channel formation region.

5. An electronic device comprising the display system according to claim 1 .

6. The display system according to claim 1 , wherein the neural network is configured to correct the image signal for only pixels in the vicinity of the boundary between the first display region and the second display region.
