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(shuō)的FPD ，它是一種取代了陰極射線管的顯示器技術(shù)，成為計(jì)算機(jī)臺(tái)式顯示器的新標(biāo)準(zhǔn)。 與通過(guò)CRT的顯示器不同，平板顯示器使用LCD (液晶顯示器)或LED (發(fā)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(dǎo)致重量減輕，尺寸減小和能量消耗減少的視頻設(shè)備類(lèi)別。 它們主要用于電視，監(jiān)視器和各種其他來(lái)源。

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

這些基本上分為兩大類(lèi)：

• 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(fā)光顯示器 ：這些是基于電能轉(zhuǎn)換為光能的設(shè)備。 它的一些應(yīng)用包括電致發(fā)光顯示器，發(fā)光二極管(LED)，等離子面板等。 圖像直接在屏幕上產(chǎn)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(fā)射型顯示器 ：這些類(lèi)型的設(shè)備使用光學(xué)效果，將太陽(yáng)光或其他來(lái)源的光轉(zhuǎn)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(yīng)用。光在屏幕后方產(chǎn)生，并且圖像是通過(guò)過(guò)濾此光而形成的。

平板顯示器的類(lèi)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(lèi)型的平板顯示器以及可用的選項(xiàng)。 市場(chǎng)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(lèi)型。 這是一種通過(guò)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(zhì)，當(dāng)電流通過(guò)時(shí)，該液晶物質(zhì)變得不透明。 在不透明區(qū)域和透明區(qū)域之間可以使用可見(jiàn)字符的形式形成這種對(duì)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(fā)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(kāi)和關(guān)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(chǎn)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(dá)5英寸。 由于具有如此眾多的優(yōu)勢(shì)，并且還可以節(jié)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(jī)發(fā)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(jī)發(fā)光二極管(OLED)稱(chēng)為有機(jī)LED，除了由有機(jī)半導(dǎo)體材料制成外，與常規(guī)LED相似。 這種有機(jī)材料位于兩個(gè)電極之間，當(dāng)使電流流過(guò)整個(gè)體積時(shí)，它會(huì)發(fā)光。 這種活性材料比普通的LED薄。 用戶(hù)可以期待將OLED用于這些零售應(yīng)用的各種新穎獨(dú)特的顯示技術(shù)。

• 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.

• 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.
