Our laptop display technologies incorporate visual output, cameras, microphones, antennas, and more. In this video, you’ll learn about some of these portable display technologies and how we use our laptop displays for much more than just viewing our computer’s output.

Most of our laptops these days use liquid crystal displays. These LCDs work by shining a light that’s on the backside of this display. And it shines through a set of liquid crystals and eventually color filters that make up the display that we see. Some of the advantages of LCD are that they are very lightweight, they use very little power, and they’re relatively inexpensive to make. So it’s perfect for a mobile device.

One of the challenges we have with LCDs is that it can be difficult to properly represent some colors, especially black. Because we’re shining a light through this display. It’s difficult to get a very, very dark pixel to show as a true black color on an LCD. These also do require that a light is behind this display. This light can be fluorescent or LED. But if we have a problem with that backlight, then we’re not going to be able to see anything on this display.

You’ll generally find two different kinds of LCD. One is the TN, or Twisted Nematic, LCD. Has very fast response times. You’ll often see this display being used by gamers. It also has a very low power draw. So it’s very good for portable devices. Unfortunately, it has a poor viewing angle. So it’s really seen best if you are looking at the display directly in front. If you’re off to the side, you may see an inverting or shifting of the color.

Another type of LCD is the IPS, or In Plane Switching, LCD. This has excellent color representation. And it doesn’t discolor or tail when you touch the device, which is great for mobile devices. Unfortunately, it’s a little more expensive to produce than the Twisted Nematic LCD.

You’ll tend to see both TN and IPS displays being used on a laptop. Just depends on exactly what model you’re getting. You tend to see the IPS and the more expensive In Plane Switching LCD on the higher end laptop computers.

With LCD technology, you must have a backlight to be able to see anything on the screen. Our older laptops used CCFL as the back light. This is a Cold Cathode Fluorescent Lamp. It used quite a bit of voltage– much more than the ones that we use these days. And so it used a lot more power on our laptop computers. They were also relatively thick. So we don’t really use this commonly on our laptop computers these days.

So today we use LED backlit LCD displays. You may sometimes see this written as an LED display. What that really means is that there is an LED backlight on this LCD display. This type of display usually puts LEDs either around the edge of the screen, or there might be an array of LEDs that will brighten or darken even in different areas of the screen, depending on what you’re looking at on your display. Most of the new laptops today are going to be LED backlit.

A very interesting mobile display technology is OLED. It stands for Organic Light Emitting Diode. This is a display type that emits light when you provide power to particular organic materials within the display itself. OLED displays are very light. They’re very flexible. It doesn’t require any glass on the display. So you can really fit it to a lot of different kinds of mobile technologies.

OLED also doesn’t require a backlight. So you can fit it into very small types of environments, especially on mobile devices. The organic compound itself is what’s lighting up inside the display. Unfortunately, this organic material degrades over time. Sometimes it can leave images on the screen. It’s also more costly than an LCD. So we don’t tend to see OLED being used today for our laptop computers.

On a laptop display, there are a number of different wireless antennas. For your 802.11 networks, you have a Wi-Fi main and an auxiliary antenna wire. And you also need an antenna wire for Bluetooth. These antenna wires are an important component of your LCD display, because the display is the highest point on your laptop. So you’ll find that the antenna wires are wrapping around the outside of your LCD display.

Here’s a view of these antenna wires. The keyboard on this laptop has been removed and has been placed right here. You can see underneath the keyboard is an 802.11 wireless adapter. And connected to that wireless adapter is a main and an auxiliary antenna wire. And you can see that these wires wrap around that keyboard underneath until it reaches the display. At that point, the wires go directly into the display. And they wrap around the outside to be able to get as much signal as possible.

Many laptops will include a webcam on the laptop itself so that you’re able to record video and audio and even broadcast that live across the network. If you do have a webcam on your laptop, there are probably specialized drivers for the webcam hardware. Even if you don’t have a webcam, there’s probably a microphone built into your laptop. You can see in this particular laptop there’s not only a webcam, but we can capture audio from the left and the right microphone that’s built into the display itself.

An LCD will need a backlight. And some of our older laptops are going to have fluorescent lamps inside of those computers. If you do have a fluorescent lamp, then you’re going to need an inverter that is used to be able to convert from the DC that’s inside of your laptop to the higher voltage AC that’s used by these fluorescent lamps. If your inverter fails or you have a problem what that inverter, then the lights are not going to work on the backlight.

You may need to look closely at the screen to see if you can see anything at all. You may be able to make out some of the images on the screen even if a backlight isn’t present. If you are able to see images on the screen and you’re simply not receiving any light through the screen, then you may have to replace the LCD inverter or the entire display itself.

Many of our newer laptops allow us to draw right on the display itself using a digitizer. This is where we can use something that looks very similar to a pen to write directly on the screen itself. It’s very common on some of our newer laptops or even these hybrid devices that allow you to connect and disconnect a keyboard so that you can convert between a traditional laptop view or use it as a tablet.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

Initial iterations of IPS technology were characterised by slow response time and a low contrast ratio but later revisions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well. IPS technology was sold to Panasonic by Hitachi.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

Backlight intensity is usually controlled by varying a few volts DC, or generating a PWM signal, or adjusting a potentiometer or simply fixed. This in turn controls a high-voltage (1.3 kV) DC-AC inverter or a matrix of LEDs. The method to control the intensity of LED is to pulse them with PWM which can be source of harmonic flicker.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.
