JVC HD-ILA Television with LCOS Technology - The Drawbacks of LCD, MOD and DLP vs JVC's Superior 3-Chip Process

There are three primary technologies that lead the microdisplay revolution —LCOS devices, DLP™ devices, and LCD devices. D-ILA is JVC’s very special type of LCOS technology that takes every factor from resolution, brightness, color reproduction and even device longevity one step further than all the others.

JVC D-ILA offers several distinct advantages over each of the other technologies.

Limited Resolution & Fair Brightness Capability

Liquid Crystal Display is a transmissive technology that allows light to pass through liquid crystal microchips to provide image data to the display screen. LCD rear projection televisions are currently limited to the lower resolution 720p format. 1080p LCD rear projection displays are not commercially available.

An additional drawback of LCD is that transistors are required on each pixel, and wires must run between each pixel to transmit the image data.

Combined, these wires and transistors limit the total area through which light can pass, which reduces the brightness of the display. At closer distances these transistors and wires are visible, creating a visible screen-door effect.

Better Brightness Capability

DMD, Digital Micro-mirror Devices, employs a reflective technology that uses micro-mirrors on hinges to reflect image data to the display screen. A true 1080p picture consists of a little over 2 million dots or pixels. Current 1080P DLP™ rear projection displays create their 1080p picture with a single chip that contains approximately one-million micro-mirrors in a 1080x960 configuration. As a result, each mirror is required to control two visible pixels in the final picture. These chips can be identified by the diamond pattern of their pixels, in comparison to the more common horizontal pixel orientation in most display devices.

An additional drawback of DLP™ is that most single chip models create color through use of a spinning color wheel. Full color images are achieved by the combining the three primary colors Red, Green, and Blue. Microdisplays employ one of two methods to compose full color images: a single chip color wheel method, as employed by DLP; or a 3-chip method, as employed by HD-ILA devices.

Highest Resolution & Best Brightness Capability

HD-ILA employs D-ILA, our exclusive Direct-drive Image Light Amplifier. D-ILA is also a reflective technology, but it utilizes LCOS pixels which require virtually no space between them. With 1080P HD-ILA, 3 D-ILA Chips are used, each containing over 2 million pixels each, in a 1920 x 1080 configuration. That means a total of over 6 million pixels are used in our light engine to create our stunning 1080p picture.

Since there is no spinning color wheel with D-ILA, there is never an issue with the “Rainbow Effect”. The viewer sees a full color image all the time. Since the light reflects off the D-ILA chips, instead of passing through them, there is also no “Screen Door Effect”.

D-ILA further improves upon LCOS by using vertically oriented pixels and by adding an inorganic alignment layer that both stabilizes device performance and maximizes chip production.

As you are probably aware, the colors on any display are achieved by the composition of the three primary colors Red, Green, and Blue - RGB. Microdisplays employ one of two methods to compose full color images:a single chip color wheel method, as employed by DLP displays, and; a 3-chip method as employed by HD-ILA devices.

Single chip DLP televisions employ a continuously rotating color wheel with a separate area for each RGB color between the lamp and the screen. As it rotates, the color wheel sends sequential pulses of each color that are combined by your brain to make up the full color composite images. While it is the human brain that does the work, many people don't notice because it happens so fast. Some people, however, do notice a flashing of colors that appear as an RGB rainbow. This effect is suitably called "the Rainbow Effect ".

	JVC’s HD-ILA televisions avoid the Rainbow Effect because they employ D-ILA’s superior 3-chip process with separate chips dedicated to each color. With D-ILA, the colors are produced simultaneously and combined through a highly specialized polarized beam splitter (PBS) which minimizes potential loss of contrast and maintains image uniformity.
The result of this total optical system with superior 3-chip process is a totally focused and continuous, flicker free image that is not subject to color flashes or Rainbow Effects. Also, since the optical system creates the color composite image before it reaches the screen, your eyes and brain do not have to do the work and that makes the HD-ILA experience a perfectly relaxing, watch and enjoy experience.
