How to choose a flat screen TV? How to choose a flat screen TV for home?

1. Contrast: The contrast ratio of plasma is currently mostly 1 and 5000:

1, even as high as 10000:1, and the contrast ratio of LCD TV is basically 400:1-1200:

1. In an environment with sufficient lighting such as a store, the picture of an LCD TV will be brighter than that of plasma; However, in a relatively dark environment at home, the liquid crystal will be more dazzling, and if the brightness is lowered, the image will lose the depth of the image and the details of the dark picture. Compared to plasma, the picture is softer, clearer and more layered.

2. Field of view angle: Due to the different principles of luminescence, although the viewing angle of plasma and LCD TV can reach 170 degrees, but when LCD TV is at a large declination angle, the picture will have a color cast, while plasma does not have this problem. Therefore, when the whole family is together** or the living room area is large, plasma TV is more suitable.

3. Dynamic clarity Response speed: Dynamic clarity refers to the visual clarity felt by the human eye when the picture is moving. Response speed is the reaction time of the TV circuit's circuit to the processing of moving pictures.

Plasma has excellent dynamic clarity and extremely fast response speed (less than 1ms), whether it is a static landscape picture or a fast sports picture, it can be clearly expressed without smearing. The response speed of liquid crystal is between 8-25ms, and the image quality is more delicate than plasma when moving at low speed, but the dynamic picture performance is far inferior to plasma.

4. Power consumption: Judging from the product data, the power of 42-inch plasma is generally about 350W, which is higher than the general power of liquid crystal of the same size. However, due to the different principles of luminescence, the power consumption of plasma and liquid crystal on different screens is also different.

Plasma is the self-emitting of screen pixels, and the power consumption also changes with the brightness and darkness of the picture, and 350W refers to its power at peak brightness. The backlight of the liquid crystal always emits light regardless of how the picture changes, so the power consumption is fixed. For example, when the screen is brighter, the power consumption of plasma is larger; In ordinary brightness pictures (news, sports events, TV dramas, etc.), plasma is similar to liquid crystal; When the picture is dark, such as a movie, the power consumption of plasma is lower than that of liquid crystal.

5. Service life: At present, plasma and LCD TVs can reach 60,000 hours of display life (display capacity attenuation of 50%), but in fact, after 16,000 hours, plasma and LCD TVs will have a certain screen display ability attenuation, and the attenuation range is about 10%-40% according to the actual use.

IPS hard screen LCD TV is good, IPS hard screen has no water ripples, more stable, 178 degrees wide viewing angle, panoramic ** more exciting; IPS hard screen is extremely fast and responsive, the moving picture is smoother, the IPS hard screen has ultra-high contrast, the pure black level is clearer, the life of the hard screen is 70,000, the power consumption temperature of the IPS hard screen is low, energy saving and power saving are more environmentally friendly, and the durability is more cost-effective.

LCD TV radiation is small, hard screen is good.

When buying a TV, I am most afraid of buying a fake 4k, teach everyone a trick, easy to avoid.

You can't just buy a TV, teach you a good way to choose a TV.

When buying a flat-screen TV for your home, you can consider the following factors:

1.Size: Choose the right size for the room, generally speaking, a flat-screen TV from 43 inches to 55 inches will fit most rooms. But if the room is smaller, it may be more appropriate to choose a smaller size.

2.Resolution: A high-resolution TV can provide a clearer picture and better visuals. At present, the mainstream resolutions on the market are 4K and 8K. If your budget allows, it is advisable to choose a TV with 4K resolution.

3.Display technology: Common flat panel TV display technologies on the market include LCD, OLED and QLED.

OLED TVs have better contrast and color performance, but ** higher. LCD and QLED TVs are more affordable options.

4.HDR technology: HDR technology can improve the dynamic range and color performance of the TV, making the picture more realistic. If your budget allows, it is advisable to choose a TV that supports HDR technology.

5.Operating system: Most flat-screen TVs are equipped with smart TV operating systems such as Android TV, Tizen, and WebOS, among others. The operating system can be chosen according to personal preferences and habits.

6.Brand and**: Brand and** are also important factors to consider when buying a TV.

Well-known brand TVs usually have better quality and after-sales service guarantees, but ** is also correspondingly higher. You can choose the right brand and ** according to your personal budget and needs.

In short, when choosing a flat-screen TV for home, you need to consider it according to your actual needs and budget, and compare the cost performance between different brands and models.
