What is laser television
To put it plainly, a laser television is a home projector, but it is different from an ordinary home projector because it is an ultra-short-focus projector that uses a laser light source technology to achieve 100-inch large-screen projection at close range. . This close distance means that the distance from the curtain is only about 30 centimeters, so it can be projected on the TV cabinet, which is why it is called "laser TV".
Of course, this kind of ultra-short-focus projector is called “laser TVâ€. Another important reason is that it has a built-in speaker, and it is sold with a “television system†made of a light-resistant frame curtain. In addition, the laser light source brings tens of thousands of hours of long life, fast switching and other features, but also allows it to have a lot of traditional TV features.
The origin of laser television
The earliest "laser" was actually changed directly from the educational projector. It did not even use a laser light source or a traditional halogen bulb. The special nature of the education industry led to the need for a projector that is as close as possible to the blackboard and can project large images. Therefore, projector manufacturers use ultra-wide-angle lenses and use the optical reflection principle to increase the projection distance to realize ultra-short-focus projection. .
One problem with this kind of ultra-short-focus projector is that there will be distortion in the four corners of the picture, but this problem is not a big problem in the education industry because the four corners of the blackboard are rarely used. But this kind of projector is placed in a home environment. This problem has become a very fatal problem. You can imagine what happens when the four corners of the movie are deformed. Therefore, early home ultra-short-focus projectors actually have such problems, and the lifespan of halogen bulbs also makes them look very ambiguous.
In the later period, after technological advancement and improvement, the distortion around the picture has been well corrected, and the use of laser light source has also made its service life comparable to that of televisions. Therefore, "laser television" has finally reached the stage and entered everyone's Sight.
Who is suitable for laser television?
Is my home situation suitable for buying laser television? Perhaps this is the next question after you understand what is the origin of laser television and laser television.
I summed up, for which groups of people can buy laser television?
The first is the need for ample budget, in short, the rich. Why do you say so, because the current laser television is still a new product, its price is relatively high, the general body plus a 100-inch screen set down more than 30,000, some good quality or even to more than 50,000. The same price for a traditional home projector, you can configure more high-end products.
Then the question came again. Since this is the case, why not use a traditional home projector?
In fact, the answer is that the laser television I'm going to talk about right for the crowd to meet the conditions - the home has been completed, there is no pre-embedding.
If you think about whether this is true or not, if you do not have a pre-layout line in your decoration, now that the decoration has been completed and you want to get a 100-inch screen, then you have two choices: First, buy a 100-inch super TV and the price reaches tens Million; second is the relatively cheap price of laser television.
To sum up, which groups are suitable for purchasing laser televisions. Simply put, the home has been renovated and there are rich people who want a 100-inch screen.
If your home has been renovated and your budget is small, then you can choose a miniature projector to achieve a big picture. Of course, you sacrifice quality. If your home is not yet renovated and you have a budget, then the plan to achieve a big picture is a traditional home projector. Remember to embed a good line in the decoration.
With 10 years of practical experience in the industry, from a professional point of view, the introduction of home projectors and professional knowledge, for consumer guidance for consumer projectors.
Power Meter is a monitoring and testing instrument which determines the power consumption of a connected appliance and the cost of the electricity consumed.
Built-in 3.6V rechargeable Batteries ( . The purpose of the batteries is to store the total electricity and memory setting
Resetting
If an abnormal display appears or the buttons produce no response, the instrument must be reset. To do this,
press the RESET button.
Display Mode
Entire LCD can be displayed for about 1 minute and then it automatically gets into Model. To transfer from
one mode to the other, press the FUNCTION button.
Mode 1: Time/Watt/Cost Display Display duration(how long) this device connect to power source.LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which means after 24 hours, it will re-caculate. LCD on second line displays current power which ranges in 0.0W 〜 9999W. LCD on third line displays the current electricity costs which ranges in O.Ocost 〜 9999cost. It will keep on O.OOcost before setting rate without other figures.
Mode 2: Time/Cumulative electrical quantity Display Display duration(how long) this device connect to power source.
LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which
means after 24 hours, it will re-caculate. LCD on second line displays current cumulative electrical quantity which ranges in 0.000KWH 〜 9999KWH without other figures. LCD on third line displays"DAY"- "1 'Will be showed on numerical part(the other three figures will be showed at carry) which means it has cumulated electrical quantity for 24hours(one day). The rest can be done in the same manner untill the maximal cumulative time of 9999 days.
Mode 3: TimeA^bltage/Frequency Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays current voltage supply (v) which ranges in 0.0V 〜 9999V .LCD on third line displays current frequency (HZ) which ranges in 0.0HZ 〜 9999Hz without other figures.
Mode 4: Time/Current/Power Factor Display LCD on first line displays the same as Mode 1 dones.LCD on second line displays load current which ranges in 0.0000A 〜 9999A. LCD on third line displays current power factor which ranges in 0.00PF 〜 LOOPF without other figures.

Setting Mode
1. Electricity price setting
After keeping COST button pressed lasting more than 3 seconds(LCD on third line display system defaults price, eg O.OOCOST/KWH ),the rendered content begins moving up and down which means that the device
has entered the setting mode. After that, press FUNCTION for swithing , then press "UP"and "DOWN" button again to set value which ranges in OO.OOCOST/KWH 〜 99.99COST/KWH.
