Flat panel screen

Types of flat panel screen

A flat panel screen is a modern display technology that has revolutionized how we view images and videos. It is widely used in televisions, computer monitors, and even screens for mobile devices. This technology has replaced the bulky cathode ray tubes (CRTs) that were used in older screens. Flat panel screens are characterized by their thin, lightweight design. This makes them more energy efficient and convenient for modern use.

Flat panel screens come in different types. Each uses a unique technology to display images. Here are the common types:

• Liquid Crystal Display (LCD)

  This technology uses liquid crystals to display images. These liquid crystals are illuminated by a backlight. There are different kinds of LCDs. They include:

  1. Twisted Nematic (TN) Panels: These are considered the basic form of LCD technology. They have a simple design. As a result, they are cheaper to manufacture. TN panels offer fast response times. They are also suitable for gaming. However, they have limited color reproduction and narrow viewing angles.
  2. In-Plane Switching (IPS) Panels: These LCDs have liquid crystals arranged horizontally. This is between two polarizing layers. They come in different configurations. These include standard IPS, advanced or hybrid H-IPS, and Super-IPS. They offer superior color accuracy and wide viewing angles.
  3. Vertical Alignment (VA) Panels: These panels have liquid crystals aligned vertically when not activated. They are divided into three types. These are traditional VA, PVA, and MVA panels. VA panels provide deep blacks and high contrast ratios. However, their response times are slower than those of TN and IPS panels.

• Light Emitting Diode (LED)

  These are a subtype of LCD screens. They use light emitting diodes as a backlight instead of fluorescent lights. There are three main kinds of LED screens. They include edge-lit LED, direct-lit LED, and local dimming LED screens.

• Organic Light Emitting Diode (OLED)

  These screens are made of organic compounds that emit light when electricity is activated. They do not need a separate backlight like LCDs. OLED panels can turn individual pixels on and off. This allows them to produce true blacks and high contrast ratios. They also offer better color reproduction and viewing angles than LCD screens. Additionally, they can be made flexible or curved.

• Quantum Dot Display (QLED)

  These screens use quantum dot technology. It involves semiconductor nanocrystals that produce specific colors of light when exposed to a light source. A typical QLED screen is an LCD. It uses LEDs for backlighting. However, the quantum dots enhance the display's brightness and color accuracy.

• Plasma Screens

  Plasma screens are a type of flat panel CRT. They use tiny cells filled with plasma gas. The cells are placed between two pieces of glass. When electricity is passed through, the plasma cells light up. Plasma screens are known for their deep blacks and wide color ranges. However, they are not as common today because OLED screens can do much more.

Function and features of flat panel screen

When it comes to flat panel screens—whether LCD, LED, or OLED—there are several functions and features that business buyers need to be aware of. Here is a comprehensive overview of the most important aspects to consider:

• Display Technology

  As already noted, flat panel screens are primarily LCD, LED, or OLED. Liquid crystal display panels use a backlight to illuminate liquid crystals that form images. Light-emitting diode panels are an advanced form of LCDs, also utilizing a liquid crystal layer but with LED lights that are smaller and more efficient than traditional fluorescent backlights. Organic light-emitting diode screens, on the other hand, have self-illuminating pixels, which means they do not require a separate backlight. This results in thinner, more flexible, and energy-efficient panels.

• Screen Size and Resolution

  Flat panel display sizes range from small 19-inch screens to massive 86-inch panels used in professional settings or large-screen TVs. In terms of resolution, standard definition is 720 pixels high. High-definition is 1080 pixels high and is divided into Full HD and FHD+. 4K Ultra HD has four times the resolution of HD at 2160 pixels high, and 8K UHD has nine times the resolution of HD at 4320 pixels high. The resolution is important because higher resolution means clearer and sharper images.

• Aspect Ratio

  This is the ratio of the screen's width to its height. The most common flat panel aspect ratio is 16:9 for HDTVs and 16:10 for computer monitors.

• Refresh Rate

  This is the number of times the screen updates the image per second. A higher refresh rate, such as 120Hz or 240Hz, means smoother motion, which is better for watching sports or playing video games. The refresh rate is measured in Hertz (Hz).

• Contrast Ratio and Brightness

  The contrast ratio is the difference between the darkest blacks and the brightest whites. A higher contrast ratio means better picture quality. Brightness is measured in nits, and a brighter screen can produce better images in well-lit rooms.

• Color Accuracy and Gamut

  Color accuracy measures how accurately the screen can reproduce colors. A wider color gamut means the screen can display more colors, resulting in more vibrant images.

• Viewing Angles

  Some flat panel displays, particularly OLEDs, have wide viewing angles, meaning the picture quality remains consistent from different angles. On the contrary, others, such as LCDs, may show color and contrast degradation when viewed from the side.

• Connectivity

  Flat panel screens come with various connectivity options, including HDMI, DisplayPort, USB-C, VGA, DVI, composite video, and component video. HDMI and DisplayPort are the most common for high-definition audio and video. USB-C is a newer standard that can carry video and power, and it is becoming more common in laptops and smartphones. HDMI and DisplayPort 1.4 can also carry audio return channel (ARC) for use with soundbars or AV receivers. Ethernet connectivity enables Internet access through a DisplayPort cable.
