LED display screens installed in meeting rooms are usually viewed from a short distance, and they are also very careful when choosing the type of LED display screens. Currently, P2, P2.5 and P3 are the most commonly used indoor LED screens, followed by small-spacing LED screens below P2.If the budget is large enough and the requirements for indoor meeting LED display are higher, P2's small-spacing indoor meeting LED display can be considered.Next will introduce you to the indoor meeting the size of LED display and its indicators：
LED display screen size of conference room:
1.P2.5 indoor high-definition small-spacing LED screen, module size 160mm*160mm and 320*160mm
2.P3 indoor LED display, module size 192mm*192mm
3.P4 LED full-color display, module size 256mm*128mm and 256mm*256mm
4.P5 full-color LED display, module size 320mm*160mm
5.P6 full-color LED display, module size 192mm*192mm
6.P8 LED display, module size 256mm*128mm. and 320mm*160mm

They are the elements that make up an electronic display system and can be independently controlled or switched on and off at different brightness levels.
3. Resolution of LED display for indoor meetings: Resolution is the number of pixels in the physical area of LED display. The more pixels per unit area, the better the detail display ability. Resolution is determined by the display size, pixel technology, pixel spacing and viewing distance.
4. Indoor conference LED display visual Angle: choose indoor LED display, should consider its installation position and Angle In order to let the audience in an indoor LED display in the meeting within the perspective to get better images, so will arrange in the perspective of the audience Viewing angles or viewing area should be greater than the best Angle of view, the best Angle of view to decided by site condition and ambient light.

Meeting rooms are generally small in area, viewing distance is relatively close.If it is to use the conventional P4, P3 specifications granular sense is strong, the definition is not very high, if the use of small spacing full color LED display effect will be very good, high definition refresh rate, and there is no sense of moles grain that is water ripple.

2. Cost of auxiliary equipment: power distribution cabinet, computer, audio power amplifier, air conditioning control card, lightning arrester and LED video processor can be selected according to requirements, and customers can also buy by themselves.
3.Steel structure cost: including the cost of manual installation generally steel frame column structure is higher than the wall installation structure cost, can also require indoor meeting LED display manufacturers to provide steel structure design drawings, customers in the local manufacturer for production.
4. Transportation cost: The cost of logistics transportation is paid by the customer on arrival.
6.Installation cost: When the goods arrive at the site, the technical engineers of the indoor LED display manufacturer will come to help guide the installation, debugging and installation without charge, but the general accommodation cost and round-trip travel cost of the technical engineers need to be paid.
