平板顯示器 (Flat Panel Display)

It is generally known as FPD, the flat-panel display is such a display technology which overtakes Cathode Ray Tube as a new standard of computer desktop displays. Unlike monitors through CRT, flat-panel displays use LCD (liquid crystal display) or LED (light-emitting diode) screens, which makes them lighter and thinner as compared to the previous monitors.

平板顯示器是通常所說的FPD ，它是一種取代了陰極射線管的顯示器技術，成為計算機臺式顯示器的新標準。 與通過CRT的顯示器不同，平板顯示器使用LCD (液晶顯示器)或LED (發光二極管)屏幕，與以前的顯示器相比，它們更輕，更薄。

These refer to the class of video devices that have resulted in the reduction of weight, size, and consumption of energy as compared to the Cathode Ray Tube. They are mainly used in televisions, monitors and various other sources.

這些是指與陰極射線管相比導致重量減輕，尺寸減小和能量消耗減少的視頻設備類別。 它們主要用于電視，監視器和各種其他來源。

These are basically and broadly divided into two categories which are,

這些基本上分為兩大類：

• Emissive Displays: These are devices that work based on the conversion of electrical energy into light energy. Some of its applications include an electroluminescent display, Light Emitting Diode (LED), panels made by plasma and many more. The image is directly produced on the screen.

  發光顯示器 ：這些是基于電能轉換為光能的設備。 它的一些應用包括電致發光顯示器，發光二極管(LED)，等離子面板等。 圖像直接在屏幕上產生。

• Non-emissive Displays: These type of devices use optical effects which converts sunlight or lights from other sources into some graphical patterns that are displayed on the screen. These have applications in LCD etc. Light is produced behind the screen and the image is formed by the filtration of this light.

  非發射型顯示器 ：這些類型的設備使用光學效果，將太陽光或其他來源的光轉換為一些顯示在屏幕上的圖形模式。 這些在液晶顯示器等中都有應用。光在屏幕后方產生，并且圖像是通過過濾此光而形成的。

平板顯示器的類型 (Types of Flat Panel Display)

There are various types of flat panel displays and options of those available. The major three types of flat panel displays available which are included in the market also are,

有各種類型的平板顯示器以及可用的選項。 市場上可用的三種主要平板顯示器包括：

1) LCD

1)液晶屏

Liquid Crystal Display. These displays have proved to be the most widely used type of display for long until recent times. This is a method of lighting through the backside which uses a panel of CFL lamps that are placed behind the two panels of glass which is filled with a liquid crystal matter, which gets opaque when an electric current passes through it. This contrast produced between the opaque and the transparent areas available forms of visible characters. These LCDs are less expensive, wider and weigh comparatively more than the LED displays.

液晶顯示器。 直到最近，這些顯示器已被證明是使用最廣泛的顯示器類型。 這是一種通過背面照明的方法，該方法使用一組CFL燈，該CFL燈放置在兩塊玻璃面板的后面，兩塊玻璃面板填充有液晶物質，當電流通過時，該液晶物質變得不透明。 在不透明區域和透明區域之間可以使用可見字符的形式形成這種對比。 這些LCD比LED顯示器更便宜，更寬，重量更重。

2) LED

2)LED

Light Emitting Diode. The concept of LED is generally the same as CFL backlighting, the basic differences in their performances are still significant. LEDs can be more quickly switched on and switched off than the CFL displays, and they can offer a typical brighter screen. Their displays are sharper, clearer and produce brighter colors and better than LCD. LEDs give a slimmer profile, with some basic commercial displays being less than even a few millimeters in depth where LCDs are up to 5-inch display. Because of thee so many advantages and also leads to the saving of energy, manufacturers have ultimately and gradually decided to discontinue the CFL displays.

發光二極管。 LED的概念通常與CFL背光相同，其性能的基本差異仍然很大。 與CFL顯示屏相比，LED可以更快地打開和關閉，它們可以提供典型的更亮的屏幕。 與LCD相比，它們的顯示更清晰，更清晰，并產生更明亮的色彩和更好的顯示效果。 LED具有更纖薄的外形，一些基本的商用顯示器的深度甚至不到5毫米，而LCD顯示器的深度卻高達5英寸。 由于具有如此眾多的優勢，并且還可以節省能源，因此制造商最終逐漸決定停止使用CFL顯示器。

OLED

有機發光二極管

The organic light-emitting diode (OLED) is referred to as the organic LED, which is similar to a regular LED, except the fact that it is made up of semiconductor material which is organic. This organic material is placed between the two electrodes, and it emits light when a flow of current is made to pass through the entire volume. This active material is comparatively thinner than a regular LED. The users can expect various new and unique display technologies that use OLED for these retail applications.

有機發光二極管(OLED)稱為有機LED，除了由有機半導體材料制成外，與常規LED相似。 這種有機材料位于兩個電極之間，當使電流流過整個體積時，它會發光。 這種活性材料比普通的LED薄。 用戶可以期待將OLED用于這些零售應用的各種新穎獨特的顯示技術。

平板顯示器的優勢 (Advantages of Flat Panel Display)

• Flat Panel Devices such as LCD produce high-quality digital images. The images produced with the help of these devices is of great quality with high resolution.

  LCD等平板設備可產生高質量的數字圖像。 在這些設備的幫助下產生的圖像具有高質量和高分辨率。

• Flat Panel monitors are very stylish and they have a very space-saving design. The space consumed by the other type of devices is comparatively more than these.

  平板顯示器非常時尚，并且具有非常節省空間的設計。 其他類型的設備消耗的空間相對要多于這些。

• Flat Panel Devices also consume comparatively less power and give out the maximum size of the image takes in minimum space.

  平板設備還消耗相對較少的功率，并在最小的空間內提供最大的圖像尺寸。

• Flat Panel Device uses its capability of full-color display.

  平板設備使用其全彩顯示功能。

• Full motion videos can also be viewed on Flat Panel Devices.

  全動態視頻也可以在平板設備上觀看。
