The flagship smartphone display that came out last year with Apple iPhone X (TEN) is summarized as 'OLED', 'HDR' and 'aspect ratio'. OLED (Organic Light Emitting Diode) displays can use power more efficiently than LCD (Liquid Crystal Display) technology, which does not need backlight to control light. Display is the most power-consuming component of smartphones.
OLED Display Advantages and Disadvantages
Efficient power consumption is not the only benefit of OLED displays. Removing the backlight will result in a thinner display module and border, which is critical for large-screen flagship smartphones. With extra space, you can build a thin body that can be held in one hand and can load more batteries. In addition, most people can feel superior to the LCD by supporting 'HDR (High Dynamic Range)' technology where OLED displays are vivid colors, black is thicker and white is brighter.
OLED displays, which are organic light emitting diodes, have been used in smartphone displays for almost a decade, but they suffer from poor screen uniformity such as burn-in or flickering. The burn-in phenomenon has been a constant problem since 2009, when applied to smartphones. When a certain pattern continues to float in one place, this "mark" refers to a phenomenon that remains on the screen and makes a residual image. In addition, vertically elongated screen designs such as 18: 9 (LG V30), 18.5: 9 (Samsung Galaxy Note 8) and 19.5: 9 (iPhone X) There is a truncated edge problem.
The OLED display, which has some of these disadvantages, is being used by smartphone makers such as Samsung, LG and Apple. It is because of its flexibility in design that it can provide durability against glass substrate with excellent battery efficiency and guarantee possibility for next generation smartphone. We compared OLED displays of four types of flagship smart phones.
