DISPLAY DEVICE
According to an aspect, a display device includes: a first panel including pixels; a second panel including light control pixels; and a light source. When any of the pixels is controlled to transmit light in accordance with an input image signal, blurring processing is applied, a blurring area is formed, and light from the light source transmits through the blurring area and the pixel controlled to transmit light and is emitted from the first panel. When a straight line connecting a user viewpoint and the pixel controlled to transmit light has an angle relative to a normal to the first panel, a center of the blurring area is at a position shifted to a side opposite to a reference normal side relative to the normal to the first panel passing through a center of the pixel. The reference normal is a normal to the first panel passing through the viewpoint.
DISPLAY DEVICE
According to an aspect, a display device includes: a first panel; a second panel disposed opposing one surface of the first panel; a light source configured to emit light to the other surface of the first panel; and an acquirer configured to acquire user information including information indicating at least one of a position of an eye and a position of a head of a user facing the second panel. The first panel includes light control pixels. The second panel includes pixels. Blurring processing is applied by which the light control pixel positioned around a pixel controlled to transmit light in accordance with an input image signal is caused to transmit light. A blurring area including the light control pixel to which the blurring processing is applied on the first panel corresponds to the position of the eye of the user or the position of the head of the user.
SYSTEM AND METHOD FOR REDUCING DISPLAY ARTIFACTS
High resolution displays, such as OLED displays, utilize complex driving circuits that can suffer from crosstalk. The crosstalk can affect the brightness of pixels in a row the display, which can be observed by a viewer as a crosstalk artifact. The severity of a crosstalk artifact may correspond to a contrast ratio of a high-contrast transition in which vertically adjacent pixels are sequentially driven by different driving signals during a scan. When a contrast ratio is above a maximum-perceptible contrast ratio, reducing the contrast ratio to the maximum-perceptible contrast ratio and can reduce, or eliminate, crosstalk artifacts. Disclosed herein are methods and devices that adjust pixels to reduce a crosstalk artifact without having a noticeable effect on contrast.
