Abstract: A method for manufacturing a light emitting device includes: providing a base layer and forming an electron transport layer including first and second transport regions. The forming of the electron transport layer includes: applying an electron transport composition including a metal oxide and a photoacid generator such that first and second preliminary transport regions are formed, and irradiating the first and second preliminary transport regions with light, and in the irradiating with the light, the amount of light per unit area irradiated on the first preliminary transport region is different from the amount of light per unit area irradiated on the second preliminary transport region.

Abstract: A method for driving an electronic device is described. The method may include receiving light passing through a display panel, generating an image signal based on the light, compensating the image signal with a compensation algorithm to generate a compensated image signal, wherein the compensation algorithm is trained with training data including a first comparison image and a second comparison image, and displaying, on the display panel, a compensated image based on the compensated image signal, wherein the first comparison image is a target restoration image and the second comparison image is a composite image.
