Which is better 15 LCD or 17 LCD?

15"The best LCD resolution is 600 x 800, recommended: Xiaoyingba KF150B, with no bright spot guarantee.

17"LCD best resolution 1024 x 768, recommended: BenQ FP71G+S, DVI-D interface, 2399

19"LCD best resolution 1024 x 768, recommended: Metz JT198A, DVI-D interface, 2599

2。If your main purpose is to browse the web, you need a large enough font, so choose 19"LCD or 15"LCD is better.

3。If the main purpose is to play games, then choose 17"LCD is better.

The display range mainly depends on how high the resolution supports,15Inch and17Inch display is the same as home TV,You won't see more pictures because of the large display screen,Hehe,The resolution is so high that you can see more。

There won't be much content to display, but because the resolution is higher, some images will be smaller and will naturally look larger.

17 is the mainstream.

And most of the 15 ones were shipped before. It's also a bit older in terms of performance.

1。the same size.

Look at the parameters, such as reaction time (the shorter the time, the better), the point distance (the smaller the point distance, the better), and the resolution (the higher the better).

After reading the parameters and looking at the brand, if the brand is good, the quality and ** will be relatively high, 2. different sizes.

If the parameters are the same, it still depends on the silver taels in your hand, if you are sufficient, of course, the bigger the better.

I still have to refer to the level of household consumption, hehe...

Of course it's 17! The cost of a 15 panel is higher than that of a 17, and now 17 is not expensive.

It also depends on other technical parameters, such as: reaction time, point distance, resolution.

17 better! Now 12ms of 17 LCDs are sold to 1999 pull!

13 screen is an organic light-emitting diode, which is a new type of product on mobile phone OLED, and is known as a "dream display". Unlike traditional LCD displays, OLED display technology does not require a backlight and uses a very thin coating of organic materials and a glass substrate (or flexible organic substrate) that emits light when an electric current is passed through it. Moreover, OLED display screens can be made lighter and thinner, with larger viewing angles, and can significantly save power.

LCD is still quite good compared to traditional CRT.

1. Because the CRT display relies on the electromagnetic field generated by the deflection coil to control the electron beam, and because the electron beam cannot be absolutely positioned on the screen, the CRT display often has different degrees of geometric distortion and linear distortion. Due to its principle, LCD does not have any geometric distortion and linear distortion, which is also a major advantage.

2.For the traditional 17-inch CRT, its power consumption is almost above 80W, and most of the power consumption of the 17-inch LCD is around 40W.

3 There is no high-voltage component like CRT in LCD, so it will not exceed the X-ray standard due to high pressure, so its radiation index is generally lower than that of CRT.

LCD LCD display is.

liquid

crystal

display

The abbreviation of LCD

The structure is to place liquid crystals in two parallel glasses, and there are many vertical and horizontal tiny wires between the two glasses, and the rod-shaped crystal molecules are controlled to change direction by electrifying or not, and the light is refracted to produce a picture. Much better than CRT, but more expensive.

LCD LCD projector is the product of the combination of liquid crystal display technology and projection technology, which uses the electro-optical effect of liquid crystal to control the transmittance and reflectivity of the liquid crystal unit through the circuit, so as to produce beautiful images with different gray levels and up to 1670 million colors. The main imaging device of an LCD projector is a liquid crystal panel. The volume of an LCD projector depends on the size of the LCD panel, the smaller the LCD panel, the smaller the size of the projector.

According to the electro-optical effect, liquid crystal materials can be divided into two categories: reactive liquid crystal and inactive liquid crystal, among which active liquid crystal has high light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system. Like liquid crystal displays, LCD projectors use twisted nematic liquid crystals.

The light source of the LCD projector is a special high-power bulb, and the luminous energy is much higher than that of the CRT projector that uses fluorescent light, so the brightness and color saturation of the LCD projector are higher than that of the CRT projector. The pixel of the LCD projector is the liquid crystal unit on the LCD board, and once the LCD board is selected, the resolution is basically determined, so the function of the LCD projector to adjust the resolution is worse than that of the CRT projector.

LCD projectors can be divided into single-chip and three-chip types according to the number of internal LCD panels, and most modern LCD projectors use three-chip LCD panels (Figure 1). Three-chip LCD projectors use red, green, and blue LCD panels as the control layer of red, green, and blue light. The white light emitted by the light source converges into the dichroic mirror group after passing through the lens group, and the red light is first separated and projected onto the red liquid crystal panel, and the image information represented by transparency under the "recording" of the liquid crystal plate is projected to generate the red light information in the image.

Green light is projected onto the green liquid crystal panel to form the green light information in the image, and the same blue light is generated in the image after the blue liquid crystal plate, and the three colors of light converge in the prism and are projected onto the projection screen by the projection lens to form a full-color image. Three-chip LCD projectors have higher image quality and higher brightness than single-chip LCD projectors. LCD projectors are smaller in size, lighter in weight, simpler in manufacturing process, higher in brightness and contrast, moderate in resolution, and now LCD projectors account for more than 70% of the overall market share, which is the projector with the highest market share and the most widely used projector in the market.
