Lcd Projector Wholesale

Lcd projector wholesale is a great option for home entertainment. They have higher contrast ratios than their traditional counterparts and are ideal for large rooms. They also have features like lens shift and zoom.

The PT-F100U has the added advantage of Daylight View, which reacts to ambient light when it’s detected by its Ambient Luminance Sensor. This helps to reduce the image degradation caused by ambient light.


One of the most important features a projector can have is brightness, which determines how large an image can be projected in a given space. Brighter projectors are generally more expensive, but they also produce higher quality images. A good rule of thumb is that the larger the screen size, the higher the brightness you will need.

Projectors have a wide range of brightness, which is measured in lumens. A higher lumen rating means that the projector is brighter, but this doesn’t always mean that the images look better.

A better metric for assessing projector brightness is color light output (CLO). This method uses the same test pattern as ANSI lumens, but measures red, green, and blue separately and adds them up to find out how bright the projector’s colors are.

This metric is important because it allows buyers to compare projectors that are rated similarly. However, it is important to note that the CLO spec does not address the issue of color balance, which can be very different between various projectors. This can be a problem when trying to compare projects in situations where ambient light is present.


A projector’s contrast ratio determines how dark or bright the darker parts of the image are and how well they can be distinguished from the lighter areas. This can make a big difference in how realistic or vibrant the images appear. The higher the contrast ratio, the better the quality of the image.

Contrast is most important when viewing movies or sports in a dark room, but it’s also a factor to consider for business presentations. The best way to compare projectors’ contrast is to read reviews from knowledgeable consumers and professional equipment reviewers and watch YouTube videos lcd projector manufacturer that include side by side comparisons. It’s important to understand that manufacturer reported contrast ratios are almost always inaccurate, and should be taken with a grain of salt.

Some projectors have a feature called an automatic iris that can improve contrast by automatically closing during dark scenes and opening when there are brighter ones. This can help to reduce gray-ish shadows and other artifacts, but it does not necessarily provide the best overall contrast ratio. For the absolute best in contrast, look for LCD projectors with a dynamic iris and light polarization to reduce stray light from the light engine.


Distributor of home theater, portable, business, overhead, 3D and classroom projectors. Features include acoustic enclosure, digital output, multilingual on-screen display, remote control and high resolution. Also offers interactive, short throw and wireless projectors. Offers projector accessories including cables, power cords and adapters. Online ordering and live customer support are available.

In LCD projectors, the video signal’s red, green and blue components are each directed to a separate imager, where individual pixels can be opened or closed to create an image. The images are then combined using a dichroic prism and projected onto the screen through the main lens. As the video signal is repeated at a regular rate, these single-color images blend together into a full-color image.

More expensive DLP models use three imagers (one for each of the primary colors) to improve their contrast ratio. Some manufacturers also use LCoS (liquid crystal on silicon) chips, which have a better contrast ratio than DLP and are based on the same technology as outdoor projection tv TVs. Two of the biggest LCoS manufacturers are Sony, with its SXRD technology, and JVC, with its D-ILA chip.


The noise produced by a lcd projector wholesale mainly comes from the cooling system and can be heard by users. If you want to reduce the noise, you should place it in a ventilated area and shut it off every four hours. It is also a good idea to use it in a well-ventilated room and avoid exposing it to dust.

The main manufacturers of LCD PJs include Epson, Sony and JVC. They offer models for the home, office and large venues. They are typically quieter than DLP PJs, although the difference can vary by brand. Some newer LCD PJs have automatic irises that can be noisy, while others have rotating color wheels that can become loud after long use.

They are less prone to image misalignments and have high contrast ratios. However, they can produce rainbow artifacts and require regular maintenance due to their air filters. They also have a restricted viewing angle and are prone to dust damage. Input lag is another factor to consider, especially for gaming. It can make a big difference in first-person shooters, racing games and platformers. Some manufacturers provide a game mode that minimizes input lag.


As with all machines, projectors require maintenance to keep them functioning at peak performance. They can be maintained with a regular cleaning routine and by storing them properly. They should also be kept away from light-robbing sources like sunlight or ambient light to prevent heat damage and color degradation.

A key problem with any projector is dust contamination. Projectors have cooling and optical systems that can become clogged with dust particles over time. This can cause filters to block prematurely, lamps to burn out, overheating and serious damage to major components. The polarized glass and modules of LCD projectors are particularly susceptible to dust build-up, which creates a blanket that blocks the transmission of light.

Whether you’re using an HD projector or an SD one, it’s important to follow the manufacturer’s instructions for proper care. Always use a clean cloth or blower to remove dust from the lens and other parts of the device. After a session, make sure to let the projector cool down before unplugging it. This will protect the lamp from thermal shock and help preserve its lifespan.
