Display Screen for Membrane Switch

Display Screen for membrane switch is devided into two types , TFT-LCD and OLED

What is the LCD?

An LCD, or Liquid Crystal Display, is a type of screen that is used in many computers, TVs, and cell phones. LCDs are very thin but are actually composed of several layers. Those layers include two polarized panels, with a liquid crystal solution between them. Light is projected through the layer of liquid crystals and is colorized, which produces the visible image.

The liquid crystals do not emit light themselves, so LCDs require a backlight. Two types of LCDs are primarily found in cell phones: TFT (thin-film transistor) and IPS (in-plane-switching). TFT LCDs use thin-film transistor technology to improve image quality, while IPS-LCDs improve on the viewing angles and power consumption of TFT LCDs.

What kind of LCDs we can supply?

• TN/HTN LCD
• STN/FSTN LCD
• TFT LCD Modules
• OLED
• AMOLEDs

What is TFT-LCD (also known as called Thin Film Transistor)?

TFT stands for Thin Film Transistor and is a type of technology used to improve the image quality of an LCD. Each pixel on a TFT-LCD has its own transistor on the glass itself, which offers more control over the images and colors that it renders.

While TFT-LCDs can deliver sharp images, they also tend to offer relatively poor viewing angles, meaning they look best when viewed head-on. If you view a TFT-LCD from the side, it can be difficult to see.

What is OLED?

OLED, or Organic Light-Emitting Diode, displays are able to deliver sharper and brighter images than LCDs, while also using less power. Unlike an LCD, which requires a backlight, OLED screens can emit their own light. This allows OLED screens to display brighter, sharper images and text, and offer better viewing angles. It also means that OLED screens are thinner and consume less power than their LCD counterparts.

OLED screens also offer faster refresh rates than LCDs, so they can deliver smoother video playback. But there are a few drawbacks to OLED displays. For one, the organic materials used to make them have a more limited life than the components of other display types. OLED screens also have the potential to be more easily damaged by water or other liquids.

Organic Light-Emitting Diodes (OLED) is a flat-screen display technology that surpasses the (Liquid Crystal Display (LCD). Its characteristics include thin, light, small, intricate, sensitive, bright colors, and power-saving. In the near future, television screens as thin as paper, and scroll-type e-paper will no longer be dreams.

OLED characteristics

• Self-lighting, no backlight required module, and color filter
• Light and thin (<2mm)
• Simple structure, high durability, low cost
• Low starting power (3 ~ 9V) and power-saving
• Free Viewing Angle, bright and distinct screen from anywhere
• High brightness
• Good luminance (16 lm/W)
• High contrast (>10, 000:1)
• Excellent picture quality in both dark view and bright view
• Fast response speed (10μs)
• Full-color capability
• Large size possible
• Flexibility (plastic base is used)
• A broad range of usable temperatures: -40℃~85℃

The above is about Display screen for membrane switch in general. Of course, sometimes, We also provide AMOLED display solution.

What is the Definition of AMOLED Display (also known as Active-Matrix OLED)?

AMOLED is the abbreviation for Active-Matrix OLED. AMOLED displays actually pair part of a traditional TFT display with an OLED display. This allows them to offer faster response times than regular OLED displays, which can be prone to ghosting when displaying fast-moving images. AMOLED displays also offer greater power savings than traditional OLED displays. Like traditional OLED displays, though, AMOLED displays may have a more limited lifetime, because of the organic materials used to make them. Also, when viewed in direct sunlight, the images on an AMOLED display are not as bright as what you’d see on an LCD.
