Description
Technical Field
The present invention relates to the field of computers, and in particular, to a data processing method and an electronic device.
Background
Organic Light Emitting Display (OLED) has many advantages such as high color, wide viewing angle, high contrast, high response speed, Light weight, thin profile, and low power consumption, and is considered as the next generation of advanced display technology behind Liquid Crystal Display (LCD). The OLED screen may be flexible relative to a generally rigid LCD screen. The OLED screen which is currently manufactured in a curved shape within a certain range is widely applied to high-end mobile phones, and exquisite appearance design and various applications are achieved. The OLED screen which is further bent and deformed is expected to realize mass production in the future, and is expected to be widely applied to the fields of tablet computers, notebook computers, televisions and the like.
Current OLEDs typically employ a structure called microcavity (microcavity) which can effectively improve the light output efficiency of the OLED, but the emission spectrum of such a structure is shifted to a short wavelength direction in a lateral direction, as shown in the following figure, where 0 degrees is a direction perpendicular to the screen, and 20, 40, and 60 degrees are angles between the viewing direction and the vertical direction of the screen. The result of human eye observation is that the color displayed on the side of the screen is cyan relative to the color displayed on the front, which is more obvious when the screen displays a white background.
In practical applications using a bendable OLED screen, a portion of the screen, such as an edge portion, may be formed in a bent shape (e.g., an edge portion of a flexible screen handset), where the side of the edge portion of the screen faces in a front direction. The edges of the screen appear cyan-colored relative to the front due to the aforementioned spectral shift. Such color differences at the edges of the screen can affect the user experience.
There are some proposals to improve the color shift in the direction of the curved portion of the OLED by optimizing the OLED structure, but in practice, the effect is still not ideal, and the color shift in the curved portion of the OLED screen is still observed.
