From their finding in 1888 to their early use in screens during the 1960s, liquid crystals have turned into a common pick with lots of useful roles in electronics. As the main part inside liquid crystal displays (LCD), these substances shift light direction to make bright, clear pictures on digital panels. The rise of LCD tech has pushed the bigger display market forward a lot, and experts predict its value will hit $178.20 billion by 2026.

As a top TFT LCD manufacturer and wholesale supplier located in Shenzhen, China, Affichage Kadi uses more than 20 years of skill in these methods to give steady industrial and medical screen options. With a factory larger than 10,000 square meters and approvals like ISO9001, ISO14001, ISO13485, and IATF16949, Kadi Display helps OEMs in car, factory, and health areas via custom TFT LCD modules, OLED displays, and panels with touch built in.
Types of LCD Technology and Terminology
A wide range of LCD kinds has appeared to fit specific needs and final settings. Screens can focus on saving power, sharp contrast, true colors, broad sight angles, heat limits, or low price. When picking LCD tech for factory or health uses, strength in tough spots and touch adding grow important. Kadi Display, as a reliable TFT LCD supplier, adjusts these setups for smooth work in car gauges and health imaging tools.
PM LCDs: Passive Matrix LCDs
Passive Matrix LCDs get signals from shared and part electrodes. A dot appears where they cross. Shared electrodes scan one by one. And segment electrodes send info at the same time—this way is named multiplexing.
The liquid crystal needs a start voltage and quick light reaction to allow multiplexing. Twisting the crystal makes both happen. PM LCDs give price benefits and great custom options. They suit simple factory controls where low energy counts. Kadi Display makes PM types for budget projects that fit old systems.

AM LCDs: Active-Matrix LCDs
Active-Matrix LCDs fix PM weak points in clearness, shades, and scale. An active piece—usually a transistor—rests at every dot. Transistors fill holders that keep voltage till update. This allows exact command.
Making steps permit tiny electrode lines. They split dots into RGB sub-dots for full shades. In health and factory areas, AM LCDs from Kadi Display aid high-clear checks and HMI screens with HDMI or DSI links.
TFT: Thin-Film Transistor
TFT means the thin-film transistors in AM screens. Stuff includes amorphous silicon (α-Si), low-temperature poly-silicon (LTPS), or metal oxides like IGZO. TFT LCDs lead in buyer, factory, car, and health roles due to flexibility. Kadi Display gives modules from 7.0 to 21.5 inches, plus 1000-nit bright types for outside factory tasks.
Liquid Crystal Configurations for PM Displays
TN: Twisted Nematic
The first sold LCD tech, TN applies a 90° twist of nematic LC between filters. Voltage changes the twist. It controls light flow. Screens can be normally white (NW) or normally black (NB). At first in part displays, TN has slim sight angles. Kadi Display adds TN-based TFT LCDs in car panels for quick reply.
HTN: Hyper Twisted Nematic
A TN kind with 90–180° twist, HTN boosts contrast in dim factory spots—a key for Kadi Display’s custom PM fixes.
STN: Super Twisted Nematic
Twisting LC 210–270° lets small voltage gaps between on/off modes. It enables more lines without active matrix. STN screens look yellow-black or blue-white. Kadi Display provides STN for single-color factory meters.
FSTN: Film Compensated Super Twisted Nematic
A fix film balances STN color effects. It betters black-white look. FSTN fits cheap health and factory needs without full shades. Kadi Display keeps even tones for right readings.
WVTN: Wide View Twisted Nematic
Hardened LC film fixes TN sight angles but keeps direct performance. WVTN suits multi-person factory HMIs from Kadi Display.
VA or VAN: Vertically Aligned Nematic
LC bits line straight to the face. Voltage tips them level. This gives deep blacks and vivid color marks on black covers. PMVA marks passive kinds. Kadi Display applies VA in high-contrast health screens.
Liquid Crystal Configurations for AM Displays
IPS: In-Plane Switching and FFS
Electrodes on one base make side fields. IPS/FFS give wide, even sight angles, no shade change, and push strength—perfect for touch screens. Kadi Display joins IPS with touch sense, aiding up to 1920×720 clearness.
MVA and PVA: Multidomain Vertically Aligned
Sub-dots split into areas with different tip ways. This broadens sight quality. MVA uses bumps; PVA shapes electrodes. Kadi Display tunes MVA/PVA for car screens.
ASV: Axially Symmetric Vertically Aligned
A Sharp-only MVA kind with circle switching, now stopped. Kadi Display keeps old support.
AIFF MVA: Amplified Fringe-Field
Mixes VA contrast with edge-field reply for active factory tasks—a Kadi Display study point.
LCD Periphery
IC, PCBA, FPC, COG
Driver ICs sit on PCBAs or FPCs. COG links ICs straight to glass via ACF. It cuts size in Kadi Display’s small health tools.
LVDS and MIPI®
LVDS allows fast, noise-safe data over space. MIPI® gives low-pin, high-flow serial link with low EMI. Kadi Display backs both in high-clear factory and carry health items.
FAQ (questions fréquentes)
What is the difference between Passive Matrix and Active Matrix LCDs?
Passive Matrix LCDs apply multiplexing with shared and part electrodes for cheap, basic screens. But Active Matrix LCDs add transistors at each dot for better clearness, shade truth, and bigger scales. They fit tough tasks.
Which LCD configuration offers the widest viewing angles?
IPS and FFS techs give the widest and most even sight angles. They remove shade shifts and contrast flips. This makes them good for multi-angle factory and health uses.
What are TFT LCDs, and why are they popular?
TFT LCDs, or Thin-Film Transistor LCDs, use thin-film transistors to guide dots exactly. They enable full-shade, high-clear screens. They lead markets due to flexibility in buyer, factory, car, and health areas.
How does Kadi Display ensure quality in its LCD products?
Kadi Display follows ISO9001, ISO14001, ISO13485, and IATF16949 rules. It uses AOI tools for checks. And it has a 10,000+ square meter site with skilled R&D for steady, custom fixes.
Can Kadi Display provide custom TFT LCD modules?
Yes, Kadi Display focuses on custom TFT LCD modules. These include scales from 7 to 21.5 inches, touch adding, and bright choices. They tailor for OEMs in factory and health fields.
