Segment LCD screens are the simplest, cheapest and lowest power-consuming display solution in the electronics world. From smart watch to water meter, this technology is still used in billions of devices.
You are designing an industrial device. 3 options appear: TFT, IPS, VA. All are LCD but there are huge differences between them. Wrong panel selection = return from customer, complaint in field.Let's talk clearly
LCD screen selection should not be made only by price; it should be made according to usage area, performance and technical specifications.A wrongly selected LCD panel both increases cost and decreases performance of your device.
IPS panels are the improved and highest quality version of standard TFT LCD technology.
TFT LCD technology is an active matrix LCD structure where each pixel is controlled by a separate thin film transistor (Thin Film Transistor).This way pixels are controlled much faster and more precisely.
Phone screen and industrial screen are not same. One works at home at 0-35°C, the other in cold storage at -30°C, inside vehicle at +80°C. Wrong screen = warranty return.
LCD and OLED technologies are the two most compared different structures in industrial screen and consumer electronics world.Basic difference is very simple: LCD needs backlight for image, In OLED, each pixel produces its own light.
TN panel, short for Twisted Nematic, is the oldest and most economical LCD technology. It takes its name from working principle of liquid crystals.
IPS and VA LCD panels are the two most compared sub-types of TFT LCD technology. Both are widely used in industry, but since their crystal structures are different, image performance completely changes.
