In today’s digital age, electronic devices are everywhere.They can interact smoothly with us and present complex information in an intuitive visual form. All of this is inseparable from electronic component displays. As a bridge for communication between electronic devices and users, the display shoulders the important responsibility of converting electrical signals into visual information and is truly the “window to vision” in the world of electronic components.
Classification of core technologies for displays
1，LCD – Liquid Crystal Display
Liquid crystal displays are one of the most widely used types of displays at present. Its working principle is based on the unique optical rotation characteristics of liquid crystal molecules.
- TN (Twisted Nematic) type: This is a relatively early and low-cost liquid crystal display technology. Tn-type LCDS have a relatively fast response speed and can meet the display requirements of general dynamic images.However, its viewing Angle is relatively narrow. When the viewing Angle deviates from the front of the screen, the color and contrast of the picture will change significantly.
- IPS (In-Plane Switching) type: IPS technology is dedicated to solving the viewing Angle problem and has a significant advantage of wide viewing angles. When viewed from all angles, the color and contrast of the picture can maintain a high degree of consistency, and the color reproduction is also more accurate.
- VA (Vertical Alignment) type: The VA type LCD is renowned for its high contrast ratio, capable of presenting deep blacks and bright whites, making the picture more layered.
2,OLED – Organic Light – Emitting Diode
OLED displays use organic materials as light-emitting elements. The biggest difference from LCDS is that OLeds do not require a backlight, and each pixel can emit light independently. This feature endows OLED with many unique advantages.
- AMOLED (Active Matrix OLED) : That is, the active matrix organic light-emitting diode, which independently drives each pixel through thin-film transistors (TFT).
- PMOLED (Passive Matrix OLED) : Passive matrix organic light-emitting diode, its structure is relatively simple and the cost is low. However, due to the limitations of the pixel driving method, the resolution and refresh rate of PMOLED are relatively low.
The application scenarios of monitors
1,The field of consumer electronics
- Smartphones: As one of the most commonly used electronic devices in People’s Daily lives, the screen display effect of smartphones directly affects the user experience.
- Television: As the core device for home entertainment, the requirements for the display of television are also constantly increasing. From traditional CRT TVS to today’s 4K and 8K smart TVS, the transformation of display technology has brought about a huge visual impact.
- Computer monitor: For office and gaming users, the performance of a computer monitor is of vital importance. Office users need monitors with high resolution, wide viewing angles and accurate color reproduction to enhance work efficiency.
2,The field of medical equipment
- Endoscope display: In endoscope examination equipment, the display is used to show the internal images of the human body collected by the endoscope, assisting doctors in disease diagnosis.
- Medical monitoring equipment: In hospital wards and intensive care units, medical monitoring equipment displays patients’ vital signs data in real time through monitors, such as heart rate, blood pressure, and blood oxygen saturation.
The future development trend of displays
As people’s demands for visual experience continue to rise, the resolution and refresh rate of displays will keep improving. In the future, 8K and even 16K resolution displays will gradually become popular, capable of presenting users with more detailed and realistic images.
To meet the development trend of miniaturization and portability of electronic devices, displays will move towards a thinner and lighter direction. Meanwhile, energy conservation is also an important goal for the future development of display technology.
Flexible display technology has already been applied in products such as foldable phones, and in the future, it will demonstrate unique advantages in more fields. In addition to foldable and rollable screens, flexible displays may also realize innovative applications such as wearables and implantable devices.
Artificial intelligence technology will be deeply integrated with displays, bringing users a more intelligent display experience. For instance, through artificial intelligence algorithms, functions such as adaptive brightness adjustment and intelligent image optimization can be achieved.
