Due to the increasingly widespread use of data projectors, there are now even stronger desires for brighter and higher resolution projectors. To respond to these desires, Sony has developed a product line of 786K-dot XGA data projector LCDs based on the unique Sony-developed DMS structure and taking full advantage of high light resistance technology and a newly-developed high aperture ratio structure. All three sizes, cm (0.9-type), and cm (1.3-type), achieve the highest brightness in their size class in the industry, and can be used in a wide range of applications, from mobile PC-based presentations to conference rooms, and even in large conference halls.

To respond to our customers desires for even brighter images with even higher picture quality, we are simultaneously releasing three new XGA data projector LCDs, a high-brightness 1.3-type device, a 0.9-type device, and a 0.7-type device. All us on this project team grappled with the main development issues, which were to achieve both high optical transmittance and high light resistance. We are convinced that Sony"s customers will be fully satisfied with this new lineup of XGA LCD products for use in applications from ultrasmall mobile projectors to high picture quality portable projectors.

tance of 26% (with ML), and the cm (1.3-type) models achieve an aperture ratio of 67% and an optical transmittance of 30% (with ML). For the cm (0.9-type) models this corresponds to an improvement by a factor of 1.2 over conventional products. To improve the light resistance, we developed the DMS structure used in previous products even further, and achieved light resistances of 1000 ANSI lm in the 0.7-type models, 1500 ANSI lm in the 0.9-type models, and 3000 ANSI lm in the 1.3-type models. In particular, the LCX038ART/AST is the industry"s first cm (0.7-type) XGA data projector LCD, and can be used to implement ultraportable data projectors. (See table 1.)

thus these devices can achieve highpicture quality images with greater evenness. All three of the model types in this release feature a contrast of 400:1 (typical), which was achieved by optimizing both the LCD design and the LCD orientation technology.

To support a wide range of applications, Sony data projector LCDs include both up/down and/or right/left inversion functions and input level shifter circuit to allow 5 V drive of the timing system. Related Sony products create an environment that allows users to get the best performance from the characteristics provided by the LCDs themselves. These products include, for the analog system, the CXA2111R signal driver and the CXA3512R high voltage drive sample-and-hold IC, which has been well-received by the market, and the CXD2467AQ, which integrates a programmable TG and RGB drivers on a single chip as the digital system structure.

The three model types in this release all adopt the TFT circuit technology developed in Sony"s previous data projector LCD products, and achieve crosstalkfree and ghost-free display. The device structure is a high-brightness structure consisting of a high light resistance DMS structure and an OCS structure, and achieves excellent uniformity. Furthermore, by adopting this device structure and the CXD3503R color shading correction IC, it is possible to correct not only for color shading in the LCD panel itself, but also for color shading in the illumination system, and

First, you need to check whether this display has On-cell or In-cell touch panel, if has, it only needs to add a cover glass on it. If not, it needs an external touch panel.

Because the shape of the cover glass depends on the design of the clients, to avoid infringement of appearance, most of the developers need different customized touch panels.

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 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.

In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.

Most panels also support true 8-bit per channel color. These improvements came at the cost of a higher response time, initially about 50 ms. IPS panels were also extremely expensive.

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.

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.

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.

Choosing for Room Size/Viewing Distance Every projector has a throw ratio. This refers to the size of image the projector can create for a given distance. This is usually a range, thanks to the optical zoom – you can find it in the user manual or specifications page online (if it"s for a projector you plan to buy). You can calculate the projection image size by dividing the distance between wall and the projector by the throw ratio of the projector. So if your projector is placed 10 feet away from the screen and has a throw ratio of 1.8-2.22, then you can get an image size that ranges between 54 – 66 inches. Ideally, you should be sitting at a distance that is more than twice the width of the image. To make things simpler, many manufacturers offer a distance calculator on their website for various models. Here, you just input a distance or required screen size.

Tip: Some aberrations can be corrected in-projector (keystone for example) but proper placement is the most preferable. If not possible due to placement/room constraints, then you can move on to digital corrections.

Screens are the best way to get the best performance from a projector. A screen will always be smoother than a wall and it will offer higher, more even reflectance. Some screens have gain – they reflect light better, thanks to shiny particles – and this helps in brighter rooms or if your projector is old or has low brightness. Some screens have black borders that add to the perceived contrast – making the image seem better. Finally, screens are also the correct shade of white/grey, solving the problem of a colour cast that some walls may cause. Having said all this, you can use a wall too – there are obvious cost advantages. If you must use a wall, make sure it is as smooth as possible (a plaster of Paris coat helps) and painted in flat white.

There are three main technologies used for projection – DLP, LCD and LED. DLP (Digital Light Processing) uses a chip made of tiny microscopic mirrors and a spinning colour wheel to create an image. DLP projectors deliver sharp images, don"t need any filters, have a better response time as well as 3D capabilities. The effective lamp life of a DLP projector is only 2000-5000 hours and some people see colour ghosting/banding in some scenes. On the other hand, LCD projectors use liquid crystal displays, have no moving parts and thus are generally less expensive. If you are on a budget a single chip LCD projector is ideal while 3-chip LCDs offer better colour saturation, lower noise levels and work better for movies. However, LCDs require constant filter maintenance and output less contrast. The LEDs in LED projectors have a lifespan of over 20,000 hours. They deliver better colours, have lower power consumption and virtually zero maintenance costs. Also, LED projectors are smaller and generate less heat. Do keep in mind that LED projectors have limited brightness compared to LCD or DLP so they are not recommended if your room has a lot of ambient light.

Tip: Some high-end projectors come with a feature called lens-shift. This is a physical rail that adjusts the lens up/down & sideways to move the image around. Obviously, this offers a lot more flexibility with regards to projector placement.

Pico projectors use LEDs as the light source due to which they can be extremely compact in size. Pico projectors can fit in your palm or be integrated into various devices like mobile phones (Samsung Galaxy Beam), tablets (Lenovo Yoga Tab 3), computers, and even digital cameras (Nikon S1000pj). While these projectors do not offer very high resolution or brightness, they are good enough to use in a small, dark room. You can get a 60-inch screen and you can connect multiple devices like smartphones, gaming consoles and laptops. Moreover, the portable size enables manufacturers to add internal storage as well as rechargeable battery in devices that weight less than 200 grams.

Tip: It"s always better to ceiling mount a projector because there are less chances of it being moved once setup. It also places the projector a fair distance away from the viewer so that fan noise and while becomes less audible.

If the projector is not placed perpendicular to the screen, the image is not rectangular – this is a keystone error. Most projectors offer digital keystone correction in the horizontal and vertical planes.

A 3 colour LCD system uses individual LCDs for red, green and blue. The light from each LCD is combined using a prism to create a final image. It usually offers better quality than single chip LCD or DLP designs.

This happens if you"re sitting too close to a projector – fine lines will be seen between the individual pixels on the screen/wall. A screendoor effect usually doesn"t matter if you"re displaying static images (or a presentation) but it affects movies/videos.
