As more and more mobile phones use OLED screens, people are more and more aware of the screen of mobile phones. OLED manufacturers will tell you the difference between OLED screens and LCDs in the simplest language. To know the difference between the two, you need to explain the working principle by the OLED manufacturer, so let's take a look at the working principle first.
[Concept of pixels]
First of all, if you look at the monitor as a complete picture, but if you actually stick it to the edge of the screen, you will find that the monitor is actually composed of countless small dots. Each dot shows its own color to make a complete picture. Because each pixel is small, your eyes will mistake it for a complete picture.
The imaging principle of the screen must be known,—— display consists of countless points, each point is composed of red, green, blue three subpixels, each pixel by adjusting the color ratio of red, green, blue subpixels to display color. Eventually, all the pixels spell out what you see.
[LCD backlight and OLED self-illumination]
The following is difficult to understand, but OLED manufacturers will explain it in the most popular language.
First, the longitudinal profile of each subpixel LCD and OLED design drawings are placed here.
The light-emitting principle of the LCD screen mainly depends on the backlight layer, and this part is usually composed of many LED backlights. Only one function can display white light. Do not let the light directly hit red, green, or blue. This layer can adjust the degree of switching by changing the size of the voltage, which is how the LCD screen works. OLEDs do not require back-to-light such as LCD screens, nor do they require an LCD layer to control the amount of light. Turn on his power and the light will turn on. So OLED is like a display with a lot of small color bulbs combined.
[Advantages of OLED screen]
Thickness: The liquid crystal has a back-to-light and LCD layer, and the thickness is much thicker than OLED, so the OLED screen is easy to make the mobile phone or display thinner, and has no effect on the display.
Bending degree: Due to the presence of the LCD screen and the backlight layer, the LCD screen will not bend significantly, and the OLED can be folded almost like origami.
Color: Contrast refers to the ratio of white and black. The higher the contrast, the darker the color of the display. The LCD screen has a backlight layer, and black is not pure black, so it is difficult to improve the contrast. OLED black does not illuminate itself, so you can directly turn off some pixels in the black area. At this time, black is almost zero, so the theoretical contrast can be said to be infinite.
Here, OLED manufacturers use a sentence to summarize OLED color, OLED is oil painting, the color is pure and delicate, liquid crystal is watercolor stroke, the color is hazy and light. OLED manufacturers think that ordinary people can distinguish the difference between high-end OLED and LCD at a glance.
