How Many types of LCD Screens Currently on the Market?
The types of LCD displays can be mainly classified from the following aspects:
Classification by display technology
TN panel display type
TN panel is a twisted nematic liquid crystal panel. It has a fast response speed, but relatively poor color performance and viewing angle. It is usually used to display text and simple graphics.
IPS panel
IPS panel is an indium gallium zinc oxide panel. It has very good color performance, wide viewing angle, and IPS viewing angle. It is usually used to display high-quality images and videos.
MVA panel
MVA panel is a multi-domain vertical alignment panel. It has a fast response speed, excellent color performance and viewing angle. It is usually used for high-end display devices.
PVA panel
PVA panel is a public viewing angle panel. It has excellent color performance and viewing angle. It is usually used for professional display devices2.
Classification by display type
Positive display
Positive display refers to the color displayed by the LCD screen under normal circumstances is the same as its original color. It is usually used to display normal images and videos.
Negative display
Negative display refers to the color displayed by the LCD screen under normal circumstances is opposite to its original color. It is usually used for special display needs.
Fully transparent
Fully transparent means that the LCD screen can still allow light to pass through while displaying images, and is usually used in situations where perspective is required.
Semi-transparent
Semi-transparent means that the LCD screen can only allow part of the light to pass through while displaying images, and is usually used in situations where semi-perspective is required.
Emissive
Emissive means that the LCD screen can emit light while displaying images, and is usually used for special display needs1.
Classification by interface type
TTL
TTL refers to the transistor-transistor logic interface, which has a faster transmission rate but a shorter transmission distance.
STN
STN refers to the super twisted nematic liquid crystal panel, which has a slower response speed but lower power consumption, and is usually used in low-power display devices.
LVDS
LVDS refers to the low voltage differential signal interface, which has a faster transmission rate and a longer transmission distance, and is usually used in high-speed display devices.
Other interface types include: MCU, SPI, QSPI, RGB, EDP and other interface types
Classification by backlight source
CCFL
CCFL refers to cold cathode fluorescent lamp, which has the advantage of good color performance, but high power consumption.
LED
LED refers to light-emitting diodes, which have the advantages of small size, low power consumption, long life, low cost, high brightness, long viewing angle and high refresh rate, but the color performance is relatively poor.
Classification by display form: LCD display, AMOLED display, bar display, circular display, industrial display, medical-grade display, car display, ink screen, transparent screen, AUO original display, Innolux original LCD screen, TIANMA original LCD screen, IVO original LCD screen, etc.
Summary
The above are the main types of LCD displays at present, each type has its own unique advantages and disadvantages and applicable scenarios. When choosing an LCD display, you can choose the appropriate type according to your needs and application scenarios.
