Which is better LED or OLED?

Should you buy LED or OLED?

LED is a light-emitting diode. LED cannot emit light by itself. It needs to release energy through the recombination of electrons and holes to emit light. It’s widely used in the field of lighting. The earliest appearance of this product can be traced back to 1962. The light emitted was the low-luminosity red light. Subsequently, due to the continuous progress of technology, the color of the emitted light covered the entire visible spectrum. Such as car signal lights, traffic lights, large indoor and outdoor full-color display screens, and special lighting sources can all see LEDs.

Which is better LED or OLED

OLED is an organic light-emitting diode, which is to apply voltage to organic matter, and it can emit light with a suitable voltage. The OLED screen has the characteristics of bending, light and thin, and strong anti-aging performance, which is both beautiful and practical. Suitable for electronics, commerce, transportation, engineering, medical and other fields. Such as copiers, ATM machines, computers, mobile phones, digital cameras, etc. The future development direction of OLED is towards the direction of automation and intelligence.

The places where LED and OLED are mainly used are different. LED or OLED, users can decide according to actual needs.

Is OLED or LCD better for eyes?

There are two main aspects of the impact of the screen on the eyes:

  • Blu-ray.

    In fact, both LCD and OLED emit blue light. So actually both products can affect the eyes.
    The biggest damage to the eyes of OLED is that OLED adjusts the brightness by controlling the light-emitting frequency. The higher the frequency, the higher the brightness. Therefore, the damage to the eyes is greater in low brightness; while the display effect of LCD is better in dark light, and the damage to the eyes is less.

  • Splash screen.

    The strobe of OLED exists, but it is so fast that the human eye cannot detect it. However, the flicker will cause obvious irritation to the eyes. OLED itself has high contrast, so it will have a certain impact on vision.
    According to the survey report released by IEEE, the stroboscopic range with a lower impact on the health of the naked eye is above 1250Hz. Most LCDs are above 1000Hz. The strobe of OLEDs is mostly around 240Hz, although there are a few manufacturers that strobe at 1920Hz.
    So LCD VS OLED, there is a basis for the eyes to watch LCD screens for a long time more comfortably than watching OLED screens.

LED vs OLED

Which is brighter OLED or LED?

The brightness of OLED is generally around 600nit. Generally speaking, to increase the brightness of OLED, it is necessary to increase the current. To increase the current, the first thing to consider is how much current the OLED can withstand. And also note that if the brightness is too high, it will affect the life of the OLED.
LED brightness generally depends on voltage, current, and power. Generally speaking, the brightness of indoor LED screens is about 1000 nits, and the brightness of outdoor LED screens is about 5000 nits.
In terms of brightness, LED vs OLED, LED has an excellent brightness advantage.

Can you tell the difference between LED and OLED?
  • Yes, we can. Let us take a closer look at the specific differences between LED and OLED. The led oled difference lies in the principles of light emission, structure and screen thickness, display effects, and service life.
    The difference in the meaning of the name: LED is the abbreviation of light-emitting diode; OLED is the abbreviation of Organic Light-Emitting Diode.
  • The principle of light emission is different: LED has a light-emitting layer, which is composed of multiple red light-emitting diodes, and uses the molecular deflection of the liquid crystal layer to display different images; each pixel of OLED can emit monochromatic light, so there is no need to emit light layer, which can directly drive the organic film to emit light through current.
  • There are also certain differences in the structure and screen thickness: the structure of the LED screen is more complicated, and it is composed of several layers, but OLED is very thin because it does not need a backlight, so the OLED screen is about one-third of the thickness of the LED screen, even thinner. OLED panels also have the feature of being bendable, which is completely impossible for LED panels.
  • Differences in display effects: LED screens can generally achieve a color gamut of 72% of NTSC, while the color of OLED screens is more conspicuous, reaching 100% of NTSC, which can meet the needs of the currently more demanding color gamut of BT 2020, but it may some problems with color temperature and color cast.
  • The difference in service life: LED screens do not have screen burn-in, OLED screens are prone to screen burn-in after a long period of use, and LEDs have more advantages in service life.
