What is the difference between a conference tablet and a projector?

Author：admin / Publication time：2022-09-08

With the integration of intelligent technology, digital technology, and information technology with office work, the market for paperless office, office automation, and networked office has developed. Conference tablets, with their few pure black technology system functions and minimalist appearance design, have achieved efficient integration and sharing of office resources. As soon as they were launched, they have sparked a storm in the increasingly fierce competition for conference equipment in the market.

So what are the significant differences between conference tablets and projectors? The editor of Detian will comprehensively compare the differences between projectors and conference tablets:

1Equipment appearance:

Projectors generally use a long cube body, with colors mostly black and white, and a compact body.

Conference tablets are known for their size, with sizes of 55 inches, 65 inches, 75 inches, 86 inches, 98 inches, and even larger. The colors are mainly black and gray, with a business style.

2Display method:

A projector projects the image onto a screen or white wall.

The conference tablet is displayed directly on the LCD screen.

3Data connection:

The projector needs to be connected to the computer through a VGA or HDMI cable. Generally, VGA cables are used, and HDMI can transmit audio and video simultaneously, which is relatively expensive.

The conference tablet adopts a wireless screen projection method, which can be displayed wirelessly through mobile phones, tablets, and laptops. It can save the hassle of wiring and eliminate the need to distribute and print materials.

4 Picture quality:

Traditional projectors have a light transmittance of no more than 10%, low brightness, low light conversion rate, and uneven light path, which makes it easy for bright areas to appear in the center of the projected image, and the surrounding images are dim and blurry compared to the middle area.

The conference tablet adopts an ultra-high definition 4K screen, with a screen resolution of 3840 * 2160p. It adopts the fifth generation color engine chip, which not only has clearer image quality and a slim appearance, but also has high contrast and wide color gamut characteristics. With a viewing angle of 178 degrees, the display is very clear in both the middle and surrounding areas of the screen.

5 Sound playback:

The projector needs to be connected to a sound system to play sound.

The conference tablet has a built-in speaker, so there is no need to purchase a separate audio system.

6Writing method:

When traditional projectors demonstrate PPTs, annotations need to be made on the PC through the mouse, and cannot be directly annotated or written on the projection screen.

The conference tablet can annotate and write directly through fingers or a stylus, with smooth handwriting and seamless switching of functions such as handwriting movement, zooming in and out, eraser, etc.

7Meeting video:

The projector is only used for display and does not have remote video conferencing functionality. But it can be used in conjunction with other remote video conferencing devices, only for display, because the projection screen is very large.

The conference tablet can achieve remote video conferencing. In remote conference mode, the screen can be shared in real-time across different locations. Even if two places are apart, the same document can be viewed and discussed simultaneously. The whiteboard function supports bidirectional annotation and writing operations, making it easy to achieve real-time interaction for multi-party discussions.

8Save and send meeting minutes:

If the projector is unable to directly share meeting content with others, it can only send meeting highlights or PPTs to others through email, notes, and other forms.

The meeting tablet can record the key points of the meeting in real time and save them. The meeting documents, annotations, and other content are all kept intact, making it convenient for future content queries. Attendees can easily take away meeting records by scanning the QR code, even if they don't take notes during the meeting, they are not afraid of forgetting the key points and delaying work after the meeting.

9Environmental requirements:

The projector, due to its projection principle, needs to be in a dark environment to achieve the best display effect and experience, and has high requirements for light brightness and darkness.

Meeting tablets have no specific requirements for lighting environment, and can achieve excellent display effects whether it is in sufficient or dim lighting.

10Installation and accessories:

Projectors often use ceiling installation methods, which require wiring, installation of screens, etc. The use requires a combination of remote control, converter, VGA cable, HDMI cable, etc., and equipment debugging is required before each use.

The conference tablet adopts a fourth class frame design, with a delicate arc-shaped outer frame and a streamlined arc-shaped base. It can be wall mounted and can be paired with a mobile tripod, without the need for additional wiring. Normal operation only requires one power cord, and there is no need to renovate the indoor space, which does not require strict installation conditions. Paired with a mobile bracket, it is flexible and convenient.

11Maintenance:

The projector requires frequent replacement of light bulbs and trapezoidal correction. It is difficult for non professionals to operate.

The conference tablet is basically maintenance free.

12Scalability:

The projector cannot be expanded.

The conference tablet can be extended for remote meetings, VIP reception, digital television, and more.

13 Life and cost:

The standard bulb lifespan of traditional light source projectors is 3000-4000 hours, while the LED projector bulb lifespan is 10000-20000 hours. The theoretical lifespan of other components of the projector, such as the motherboard, is about 10 years. Assuming that a projector replaces its light bulb every 2 years on average and costs 1000 yuan per bulb, the cost of replacing a light bulb alone can reach up to 5000 yuan over a period of 10 years. In addition, purchasing a projector, screen, spare parts, and later replacement, the cost of a projector will exceed 10000 yuan.

The service life of conference tablets far exceeds that of projectors, with a lifespan of at least 60000 hours. According to a normal usage of 8 hours per day, they also need to be used for at least 20 years, with almost no maintenance costs during this period.
