OLED display is an advanced display technology that uses light-emitting diodes (OLED) constructed of organic materials. Compared with traditional LCD displays, OLED has significant improvements in color saturation, response speed, contrast and viewing angles. improvement of. In practical applications, the viewing angle width and energy saving of OLED displays are also issues that users are very concerned about. This article will discuss these two issues in detail.

 

1. How wide is the viewing angle of the OLED display?

Viewing angle refers to the quality and quantity of visual information obtained by the human eye when observing the screen at different angles. Due to the limitations of its structure and optical characteristics, the traditional LCD display has a relatively narrow viewing angle. Generally, a clear image can only be observed within a range of 30 degrees up, down, left, and right. The OLED display adopts the concept of self-illumination and does not require a backlight, so it has a wider viewing angle.

 

1. Structure of OLED display

OLED displays are composed of inorganic or organic films, and each layer has different electrical and optical properties. At the bottom is a glass or plastic substrate with multiple layers of organic material, one of which is used to trigger light emission. Driven by a certain current, organic light-emitting materials will emit photons in a specific wavelength range, and the color of the photons is determined by its energy level. A display is made up of multiple pixels, each with a different light-emitting layer that can be turned "on" and "off".

 

2. Viewing angle characteristics of OLED display

The structure of the OLED display determines that it has some obvious advantages in terms of viewing angle characteristics, as follows:

 

(1) Wide viewing angle

OLED light-emitting components are self-luminous and do not require a backlight. The light will not be scattered and reflected at the light-emitting device, so a wider viewing angle range can be achieved. In the horizontal and vertical directions, the OLED display reaches a viewing angle of more than 160 degrees, which basically meets the needs of observing images from different angles.

 

(2) High performance purity

The pixels of the OLED display are composed of the three primary colors of RGB, and each sub-pixel is composed of multiple color filters. When displaying colors, OLED's color purity is very high, its color contrast is significantly enhanced, and it can present brightly colored and gorgeous images more clearly.

 

(3) Visual effects and energy consumption optimization

The OLED display realizes global brightness adjustment (that is, the brightness of the entire screen can be controlled), which can adjust the display within a specific range to optimize the display effect while reducing power consumption. As a result, OLED can better manage the brightness of pixels to display low energy consumption levels that are sufficient but not wasteful.

 

2. How to save energy?

 

Under the requirements of green environmental protection, energy conservation and emission reduction, people are paying more and more attention to the rational use of energy in their daily lives and work, and OLED displays are no exception. Although OLED light-emitting diodes are more environmentally friendly and easier to recycle than traditional chemiluminescent materials, and their energy-saving properties are generally recognized by users, the current price of OLED displays is still relatively high, so how to save energy and make OLEDs have a longer service life has become a A very important question.

 

1. Adjust screen brightness

The flexibility of OLED allows it to easily adjust the screen brightness, allowing the device to adapt to the brightness requirements in different environments and reduce overall power consumption. You can use the automatic brightness adjustment function to automatically reduce the brightness when the light becomes weak, thereby reducing power consumption.

 

2. Close unused apps

In actual use, we will inevitably use some applications, such as web browsers, video players, etc. Although these applications have been optimized to provide less power consumption, their energy consumption on the device is still considerable. Therefore, if you close these unused apps, you can further extend the life of your device while reducing the cost of power for subsequent use.

 

3. Manually turn off the OLED screen

Even when you're not using the device, OLED screens still consume a lot of power. Therefore, if you are diligent about turning off the OLED screen manually, you can reduce a lot of power consumption and save OLED usage time and battery life.

 

4. Avoid overuse of equipment

Although OLED emphasizes bright colors and gorgeous image effects, frequent and long-term use of devices in high-brightness display modes will also affect the OLED life cycle and accelerate its damage. Therefore, to save energy, you can reduce excessive use of devices and maintain reasonable usage time.

 

Okay, the above is a detailed introduction to the viewing angle width and energy saving of OLED displays in this article. In short, the viewing angle width of the OLED panel is unmatched by traditional LCDs, and because OLED has unique natural light-emitting properties, coupled with its excellent environmental protection and energy saving, its future application prospects in various smart terminals and display technology fields Very vast. Of course, during daily use, we should also pay attention to adjusting the screen brightness appropriately and avoid using the device too frequently to ensure its long-term stable operation and service life.
