LCD Technology:

LCD (Liquid Crystal Display) works on a transmissive technology. LCD projectors project light onto mirrors which split it up into its 3 primary colours: red, green and blue. The colours then pass through three separate glass panels (actually prisms), which is why this technology is referred to as 3LCD. When light is projected through the LCD panels, individual pixels are opened or closed to allow light through or block it. The separate colours are then converged using another prism and projected on to the screen.
LCD technology is designed to project bright, clear and vivid images. LCD projectors are engineered for high light efficiency, improving image brightness, generating less heat, and costing less to run. They faithfully reproduce the visible color spectrum to deliver a true expression of color, with smooth gradations in the dark and light areas. With the use of 3 different panels of RGB , there is least color breakup and hence giving true & natural color image. This technology uses light more efficiently and provides greater impact to your presentations with excellent color luminance.

DLP Technology

DLP (Digital Light Processing) works on an optical semiconductor known as the DLP® chip, which was invented by Dr. Larry Hornbeck of Texas Instruments in 1987. DLP chip is a reflective surface made of thousands of tiny mirrors. Each mirror represent a single pixel.

Single Chip DLP Technology – In a projector with a single DLP chip, colors are produced either by placing a color wheel between a white lamp and the DLP chip or by using individual light sources to produce the primary colors, LED’s or lasers.

3 Chip DLP Technology –

There are no color wheels and hence no rainbow effect. These projectors uses a prism to split light from the lamp, and each primary colour of light is then routed to its own DLP chip, then recombined and routed out through the lens. These are found in higher end home theatre projectors, large venue projectors and DLP cinema projection systems found in digital movie theatres.

Laser Technology Light-Source

Lasers are the future of projectors. Light generated with laser diodes inherently have a longer and more stable brightness level that decreases at a much slower rate than conventional lamp based systems. The laser technology offers the highest image quality while its operating life span far exceeds traditional lighting methods.                                                     WHY LASER?

The three most important technologies, laser phosphor, RB laser and RGB laser, are described below


Vivid colour representation
High brightness
Low projector weight


Natural colours and good brightness uniformity
High brightness
Excellent white reproduction
Compact size


Excellent colours and very good brightness uniformity

DCI (Digital Cinema Initiative) compliant colour space


Brilliant colours and brightness uniformity
Higher brightness
Lower power consumption
High light efficiency
Wider colour space


Best colours and brightness uniformity
Highest brightness
Adobe-RGB, DCI compliant
Hybrid Light Source

Pure Laser Technology

RGB laser uses the so-called pure laser technology. Red, green and blue lasers are delivered directly to the 3 DLP image chips.

Projection Screen

When it comes to projector, installation of projection screen should happen parallel for good projection and clarification as projecting on a wall wouldn’t be a good option. Just as you would not prefer inferior speakers in your royal car sound system likely don’t degrade your projector quality by avoiding projection screen. Crystal is a specialist projection solution provider with an advanced screen quality of almost all renowned brand with quality.

There are wide varieties of projection screen that are available in the market. All you need to do is to take a serious advice of a technical expert to choose the best that suits your application.

There are ample screens with different variations of fabrics, same have high gain while some of less gain. There are screens of different viewing angle and tension. So if you want a good quality screen that suits your usage & application, it is worth taking our technical expertise suggestion & solution.There are many different formets available, one can decide according to their usages.

Projection Screen – Surface/Fabric 

Some of the standard quality terms that Crystal adhere for right selection of screen:

High Gain Surface 
When there is ambient light or brightness or if you are using low brightness projector then the screen with high gain are considered best for best of projection.

White Matt Fabric
Matt fabric are considered the best fabric for projection screens . It provides gain of around 1.0:1 which gives the reflection equal and diffuse lights in all directions uniformly at all angles. White matt fabric screens are considered best in a dark room where there is not ambient light. But the place where there is bright light , grey screen are preferred most .

Projection Screen - Aspect Ratio & Format

Screen formats are determined by the specific aspect ratio of the screen. Aspect ratio is nothing but the fractional relation of the width of a video image compared to its height .

Projection Screen – Sizes 

Screen sizes and formats are decided by a projector type. Screen sizes are mostly measured diagonally in inches . Following are some of the standard sizes & formats based upon which one can decide an option .


Some of the renowned brands that Crystal mark its quality and genuinty to its clients are:
