As an AV fever, the temptation of the big screen is still irresistible. The TV is smaller and smaller, and after 60 inches, the price jumps badly. Therefore, the projection has become the easiest solution for me to achieve a large screen. , From the nuts G1, more than 2,000 micro-projections made me realize the big screen dream.
The advantage of micro-projection is that it is compact and easy to place, it has a built-in system, no external player, and the LED light source has a long life. If you don't have the trouble of changing the lamp, you can watch it on TV, but after a long time, it will not meet the resolution of 720P. And brightness. Therefore, the heart began to itch again, and turned his attention to the traditional light bulb machine.
Sorting machineDafa's HW40ES, Sharp's Z600, and Epson's TW6600 can't afford it all. .
As a poor silk, these can only be underwater, the first consideration is still cost-effective, about 5,6000 is my first consideration,
W1070 is an entry-level machine that can't be skipped. Since it was launched in 2012, it has received a lot of affirmations, and the market has responded well. In the later period, it also introduced a number of derivative upgrade products. W1070+ has 6 major upgrades compared to W1070, of course. My favorite is to improve the brightness, side-shooting function is also more practical. The first product to consider. .
Epson TW5200 is another entry into the classic models, 3LCD masterpiece, better than DLP in color performance, and the price is very cheap, Haitao more than 4,000 can get it, TW5210 is an upgraded product of 5200, which can be considered an alternative. However, the problem with low-end LCDs is that the crystal lattice is more pronounced and the aging decay is faster.
Optoma HD25 is another product that we have chosen more. The quality has also received a lot of affirmation, and Optoma's machine supports VESA 3D, which is much better than DLP 3D. Like watching 3D is a good choice. But the quality control of Optoma does not seem to be very stable.
ACER's machine originally I did not touch much, and I feel less home machines, but this time the V7500 release still makes me shine, especially the brightness of 2500 lumens, 2W:1 contrast ratio, RGBRGB 6-segment color wheel, these Optical index is very good, and 1.4x optical zoom, up and down the lens adjustment, 2 meters cast 85-inch short-throw projection, 4-angle trapezoidal correction is very convenient for the small living room hanging placement. With the addition of new elections and no selection of old ones, they finally bite the teeth on this unfamiliar product.
Acer Acer V7500 Unpacking: 
Acer Acer V7500 packaging
The outer box is not large, the appearance is not bad
Acer Acer V7500 with the bag
The included bag is very good.
Acer Acer V7500
The machine looks very good, particularly large glasses look good, but also comes with a dust cover.
Acer Acer V7500 lens
What makes the V7500 my heart is that this lens supports up and down adjustment, and also supports 1.4 times zoom, all-glass lens. When the new house is dropped, it is easier to adjust.
Acer Acer V7500 Control Panel
control panel. More intuitive, all controls can be completed here.
V7500 is the most special is the side of the interface set
Acer Acer V7500 Side Interface
The interface is still quite rich, especially 2 HDMI, a high-definition machine, a box, so that local playback and online play can have. More convenient.
Acer Acer V7500 Remote Control
Remote control, really ugly. Haha.
Comparison of appearance of acer Acer V7500 and nuts
Contrast with nuts.
The projection distance is about 4M, and the projected area is estimated to be 150 inches. Compared with the 55-inch micro-whale, the brightness is almost the same, and it finally understands the sense of sunlight that others have said. . .
Last screen shot, the level is a bit bad, the actual effect is much better,
Acer Acer V7500 screen shot
advantage:
High brightness, good contrast, dark details in place
RGB RGB6 color wheel with ColorBoost 3D color technology, so that its performance in color is also very good
Short focus, 1.4x optical zoom, up and down movement, and 4 angle adjustment make it easy to install the machine.
1080P full HD picture to be rich and delicate.
Little fan noise
insufficient:
Remote control is a bit uncomfortable
Side interface is not very convenient
In general, I was very satisfied with this upgrade. There was a great improvement in brightness, quality, and color. If you want to set up your own theater, it is recommended to use a light bulb. Micro-projection is more suitable for use in the bedroom. .
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
