The biggest flaw of OLED is the burning screen, which is determined by the characteristics of the screen material itself. In order to avoid the above problems, Apple applied for a new patent to try to improve this problem. Apple said in the patent application that when a static image is displayed on the display for a long time, it may cause the screen to burn, that is, uneven wear of the pixels of the display. If you are not careful, the burn-out effect may cause undesirable ghost images on the display.
In order to reduce the risk of burn of the face elements of the watch, the control circuit in the electronic device can impose burn constraints on the attributes of the elements on the surface of the hand, such as peak brightness constraints, dwell time constraints, color constraints, constraints on the shape of each element, and element styles Constraints.
These constraints may help avoid situations where static elements are more burnout than dynamic elements. Apple electronically alleviates this problem by balancing its so-called "dwell time" (the time the user actually looks at the screen) and reducing the display intensity, so that it will not stay on any given pixel or pixel set for a long time. In addition, in order to reduce the risk of burnout, the control circuit can be configured to dynamically adjust the position during operation.
Apple plans to repeat the radial inward and outward movement to disperse pixel wear. If necessary, the overall picture size can be adjusted proportionally, and the always-on picture can be adjusted to 95% of its nominal (100%) size to help reduce the burning effect.
