Title:
DISPLAY DEVICE AND MOVING BODY
Document Type and Number:
WIPO Patent Application WO/2018/002766
Kind Code:
A1
Abstract:
Provided is a display device in which display quality is not readily affected by the intensity of external light. An image signal for a display element is corrected in accordance with a parameter obtained by computation processing using a neural network. In a computation circuit, a first circuit outputs a third signal to a third circuit via a second circuit, the third circuit outputs a signal corresponding to the amount of current of the signal input thereto to a fifth circuit via a fourth circuit, the fifth circuit outputs a fourth signal externally, and the fifth circuit generates a sixth signal from the difference between a fifth signal and the fourth signal. The second circuit and the fourth circuit are each provided with an analog memory for storing data corresponding to a weighting coefficient, a write circuit for altering the data, and a multiplier circuit for outputting the input signal as a signal that has been weighted in accordance with the data. The analog memory is provided with a transistor having an oxide semiconductor in a channel forming region.
