Reason 1: the notebook computer is sensitive to energy consumption, especially under the current trend of pursuing light and thin fuselage, in order to be able to control the energy consumption of the hardware part under the premise of ensuring the continuation of the service, it is particularly important to control the energy consumption of the hardware part.
According to the comparison test of the same platform, on the premise that both the ips led screen and the oled screen model of the same model reach the same screen level, due to the different load, using the oled screen will shorten the battery life by 10% and 25%. Among them, the battery life is the most affected when running peacekeeper surfing test program.
This is due to the white background of most web pages, so the screen brightness is very high, and according to the current technical level, the energy consumption of fully luminous oled display screen is higher than that of led display screen. Because the oled display does not need to use a backlight source, each pixel can emit light independently, and when all pixels emit light, the energy consumption of the oled display screen will be much higher.
So in scenarios where all pixels are not required to shine, such as playing video tests, battery life is least affected. There are also several laptops with oled panel technology on the market, but they have one thing in common: a 4 k resolution screen.
Reason 2: The cost of the oled is high, the advantage of the application of the notebook and the display is not significantly less noticeable on the display, and the cost is also the same, although the current oled screen has been greatly improved over the production capacity and the cost over the years of development and technology iteration,
However, compared with the lcd screen, which is lower in cost and has achieved large-scale production, the oled is obviously not comparable to the price and supply of the market terminal. The 27-inch 2-k-resolution 144hz refresh rate is currently less than $2,000, while a 27-inch oled display may need to be priced at $7,000 to $8,000, even with the ips professional-level graphics display with a 100% srgb color gamut. It is clear that such a price is generally difficult for consumers to accept, and the display manufacturer is not too keen to roll out the oled display.
Reason 3: the accuracy of oled color restoration is poor oled has its advantages in contrast and wide color gamut, and you may wonder why you don't launch oled display products for mapping or video surveillance in the professional market. But the actual situation is, although the oled display is particularly advantageous, but in the color restore accuracy is poor, and needs to optimize to have the accurate color restore ability the product price is also very high, Sony pvm image monitor uses the 17-inch oled panel, the price is as high as 25000 yuan, obviously this kind of product is only aimed at the professional high-end market, but is not conducive to the promotion of the oled panel in the display market.
Reason 4: in addition to the price of the oled, the oled panel cannot be widely used on notebook screens and display screens, and there is also a fatal flaw, that is, burning screens. Whether you use windows or macos, desktop, the taskbar or status bar is displayed, and these long-standing display parts can easily cause the screen to burn. In order to reduce the probability of screen burning, the screen using oled screen since iphone x adopts the method of combining software and hardware. First, a special display chip is built in, which enhances the hardware level function of picture quality and anti-burn screen. At the software level of ios system, the gesture bar at the bottom and the top status bar will slightly move the position of the display pixels every once in a while, and the position of the same picture will appear burning screen for a long time. After the combination of software and hardware, it can only ensure that the oled screen of iphonex can work continuously for about 500 hours
