What is the difference between a conference tablet and a projector? How to choose?

What are the significant differences between conference tablets and projectors? Are conference tablets really better than projectors? How to use the conference tablet? Which one is more convenient for later maintenance?

We will comprehensively compare the differences between projectors and conference tablets:

1. Equipment appearance:

Projectors generally use a rectangular cube body, mostly black and white, and have a small body.

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

2.Display mode:

The projector projects the image onto a screen or white wall. The conference tablet is displayed directly on the LCD screen.

3.Data connection:

The projector is connected to the computer through a VGA cable or HDMI cable. Generally using VGA cable, HDMI can transmit audio and video at the same time, which is relatively expensive.

The conference tablet displays wirelessly through mobile phones, tablets, laptops, etc. Not only does it save you the hassle of connecting, but it also eliminates the need to distribute and print data.

4. Picture quality:

The light transmittance of traditional projectors does not exceed 10%, the brightness is not high, the light energy conversion rate is low, and the light path is uneven, making it easy for a bright area to appear in the center of the projection, and the surrounding image to be darker than the middle area.

The conference tablet uses an ultra-high-definition 4K screen with a screen resolution of 3840*2160p. It uses a fifth-generation color engine chip, which not only has clearer picture quality, but also has the characteristics of high contrast and wide color gamut. With a 178-degree viewing angle, the display is very clear regardless of the middle area of the screen or around the screen.

5. Play sound:

The projector needs to be connected for sound to play.

The conference tablet has built-in speakers, so there is no need to purchase separate speakers.

6. Writing method:

When presenting PPT with a traditional projector, annotations need to be made through the mouse on the PC, and annotations cannot be made directly on the projection screen.

Annotate directly from the meeting tablet with your finger or touch pen. Smooth, seamless switching of handwriting movement, zooming in and out, eraser and other functions.

7. Conference video:

The projector is for display only and does not have remote video conferencing capabilities. However, because the projection screen is large, it can be displayed with other remote video conferencing equipment.

Conference tablets enable remote video conferencing. In remote meeting mode, the screen can be shared in different places in real time. You can view and discuss the same document at the same time even if you are in two places. The whiteboard function supports two-way annotation writing operations, easily realizing real-time interaction among multi-party discussions.

8. Save and send meeting minutes:

Projectors cannot share meeting content directly with others, and can only send meeting keynotes or PPT to others through emails, notes, etc.

The conference tablet can record and save the key points of the meeting in real time, and completely save the meeting documents, comments and other content to facilitate subsequent query of the content. Participants can easily take away the meeting minutes by scanning the QR code. Even if they do not take notes during the meeting, they are not afraid of forgetting the key points of the meeting and delaying their work.

9. Environmental requirements:

Due to its projection principle, the projector needs to achieve the best display effect and experience in a dark environment, and has high requirements for light and shade.

The conference tablet has no requirements on the light environment. Whether it is full light or dim light, it can achieve excellent display effects.

10. Installation and accessories:

Projectors are usually ceiling mounted and require wiring. Install curtains etc. Use requires a combination of remote control, converter, VGA cable, HDMI cable, etc., and debug the device before each use.

The conference flat panel adopts a four-level frame design, with an exquisite arc-shaped frame and a streamlined arc-shaped base. It can be wall-mounted and can be matched with a mobile tripod. No additional wiring is required. Only one power cord is needed for normal operation. There is no need to modify the indoor space and the installation conditions are not strict. The mobile stand is flexible and convenient.

11. Maintenance:

Projectors require frequent lamp replacement and keystone correction, which is difficult for non-professionals to operate. The conference flat panel is basically maintenance-free.

12. Scalability:

The projector cannot be expanded. The conference tablet can expand remote conferences, VIP reception, digital TV, etc.

13. Lifespan and cost:

The service life of the standard bulb of a traditional light source projector is 3,000-4,000 hours, and the service life of an LED projector bulb is 10,000-20,000 hours. The theoretical lifespan of other projector components such as the motherboard is about 10 years. Assume that a projector replaces the bulb every two years on average, and a bulb costs 1,000 yuan. In the past ten years, the cost of replacing a light bulb has been as high as 5,000 yuan. In addition, the cost of purchasing the projector, curtains, spare parts and later replacement will exceed 10,000 yuan. The service life of conference tablets far exceeds that of projectors, with a service life of at least 60,000 hours and a normal use of 8 hours a day for at least 20 years, with almost no maintenance costs during this period.
