Interactive electronic whiteboard quality slightly, so from the touch screen interactive whiteboard perspective of demand, the current design of lattice is recognised by the market, so from the point of view of advantage and market, this is a screen and a good example of traditional design improvements. Good product development can also be combined with market demand, to help users to use better. First, dot-matrix interactive electronic whiteboard is practical is developed in recent years to the design of a product, the good design of interactive electronic whiteboard and use for users is quite reasonable, by contrast, it is of practicability, design improvement and product demand comprehensive adjustment, also is a kind of advantage products to user requirements.
It is also a display design and use of a standard project, the design interactive whiteboard for schools of the display and use of cost-effective and cost effective. , therefore, is not only the interactive electronic whiteboard, and from the aspects of quality and product procurement has good popularization and use of a wide range of services to seize the current market, improve the performance of services. Third, security and reliability is also an interactive electronic whiteboard should consider when the choice question, whether it is in fact is a focus of attention of the user or the rationality of the price and the product of the combination of the actual effect, etc., so the choice of the screen and adjust to upgrade more realistic, to grasp the service safety and reliability of products, in the event of a problem or failure under the situation of good comprehensive 4k smart board upgrade. Lattice design is a striking feature of the current display design. Mastering the adjustment model of product design, the product of the personalized needs of the product, the development of the market and the overall use of combined, is a good change.
LCD is composed of long rod molecule organic compounds. In nature, the long axis is roughly parallel rod molecules. The first characteristic of interactive electronic whiteboard is, they must fall between two concave surface to work properly. Two grooves perpendicular to each other in the plane of the cross (90 degrees), north and south, this means that if a planar molecule is aligned, then another plane of molecules are aligned, "between two surfaces were forced to 90 degree turn. Light travels along the direction of molecular, so when it passes through the liquid crystal can be 90 degrees. But when the voltage applied to the liquid crystal molecules are vertically again, so that light can launch directly without being distorted. The second characteristic is the interactive electronic whiteboard, it relies 75 inch smart board on the polarizer and light itself, random scatter light in all directions. Polarizer is actually a series of parallel lines more and more thin. These lines form a grid, blocking all not parallel to the light. Polarization line perpendicular to the first line, so it is completely blocked out the polarized light. Only when two filter line are parallel, or distorted light itself to match the second filter, the light to pass. Interactive electronic whiteboard consists of two mutually perpendicular polarization filter, under normal circumstances, therefore, any attempt to penetrate the light should be blocked. 75 smart board But because the two kinds of liquid crystal filter is distorted, when light through the first filter, come out from the second filter, the liquid crystal molecules make the light distorts the 90 degrees. On the other hand, if the LCD voltage, molecules will rearrange into completely parallel, so the light will not be a second filter distortion and block. In short, the energy will block the light, no energy will make the light disappeared. Of course, you can also change the arrangement of the interactive electronic whiteboard, the l plate, the lamp is on the power supply, but no power source is blocked.
