With the integration of intelligent technology, digital technology, and information technology with office work, markets such as paperless office, office automation, and online office are developing. Conference tablets have caused a storm in the increasingly fierce competition of the conference equipment market, as they have rare pure black technology system functions and simple designs, achieving efficient integration and sharing of office resources.
What are the significant differences between conference tablets and projectors? Detian editor will comprehensively compare the differences between projectors and conference tablets:
1. Equipment appearance:
The long cube body usually uses a projector, with black and white colors, and the body is compact.
Conference tablets are called "big" and come in sizes of 55 inches, 65 inches, 75 inches, 86 inches, 98 inches, and even larger. Its main colors are black and gray, with a commercial style.
2. Display method:
The projector projects the image onto curtains or white walls.
The conference tablet is displayed directly on the LCD screen.
3. Data connection:
Connect the projector and computer via VGA or HDMI cable. Usually, VGA cables are used, and HDMI can transmit audio and video simultaneously, which is relatively expensive.
The conference tablet adopts wireless screen projection, which can be displayed through wireless screen projection on mobile phones, tablets, and laptops. It not only saves the trouble of wiring and connecting, but also can be done without distributing or printing information.
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 image is darker and more blurry than 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 the characteristics of high contrast and wide color gamut. Whether in the middle area of the screen or around the screen, a 178 degree perspective is very clear.
5. Sound playback:
Before playing sound, the projector needs to be connected to the audio system.
The conference tablet has a built-in speaker, eliminating the need to purchase a separate audio system.
6. Writing method:
During the PPT presentation, traditional projectors need to annotate and write directly on the projection screen through the mouse on the PC.
The conference tablet can be annotated and written directly with fingers or a stylus, ensuring smooth handwriting and seamless switching of functions such as handwriting movement, zooming in and out, and eraser.
7. Meeting video:
The projector is only used for display and does not have remote video conferencing functionality. However, due to the large size of the projection screen, it can be used in conjunction with other remote video conferencing devices for display purposes only.
Meeting tablets can enable remote video conferencing. In remote meeting mode, the screen can be shared in real-time in different places. Even if separated by two places, the same document can be viewed and discussed simultaneously. The whiteboard function supports bidirectional annotation writing operations, making it easy to achieve real-time interaction for multi-party discussions.
8. Save and send meeting minutes:
If the projector cannot directly share meeting content with others, it can only send meeting highlights or PPTs to others through email, notes, and other means.
The conference tablet can record the key points of the meeting in real time and save them. Conference manuscripts, annotations, and other content can be fully saved, making it convenient for future queries. Participants 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 to forget the key points and delay work after the meeting.
9. Environmental requirements:
Due to its projection principle, projectors must achieve the desired display effect and experience in dark environments, with high requirements for the brightness of light.
The conference tablet does not require a lighting environment, and can achieve a display effect of [sensitive words] regardless of whether the light is sufficient or dim.
10. Installation and accessories:
Projectors are usually installed from the ceiling and require wiring, curtains, etc. A combination of remote control, converter, VGA cable, HDMI cable, etc. is required, and the equipment needs to be debugged before each use.
The conference tablet adopts a fourth class border design, exquisite curved frame, streamlined curved base, can be wall mounted, and can be paired with a mobile tripod. No additional wiring is required, only a power cord is needed to operate normally, and there is no need to rebuild indoor space or require installation conditions. Paired with a mobile bracket, it is flexible and convenient.
11. Maintenance:
Projection instruments require frequent replacement of light bulbs and trapezoidal correction. Non professionals find it difficult to operate.
The conference tablet is basically maintenance free.
12. Scalability:
Cannot expand projector.
Meeting tablets can expand 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 service life of other projector components such as the motherboard is about 10 years. Assuming a projector replaces light bulbs on average every two years, each bulb costs 1000 yuan. In the past decade, the cost of replacing light bulbs alone has reached as high as 5000 yuan. In addition, if a projector, curtains, spare parts, and subsequent replacements are purchased, the cost of one projector will exceed 10000 yuan.
The lifespan of conference tablets far exceeds that of projectors, with a lifespan of up to 60000 hours. A normal usage of 8 hours per day takes 20 years, during which there is almost no maintenance cost.
