What is a laser TV? LCD TV resolution problem

Whether you buy a good or bad TV, resolution is a crucial parameter that determines the comfort of watching TV! Below we will learn about the relationship between resolution and high-definition display of images for screens of the same material and size, as well as the difference between LCD TVs and plasma TVs. I hope it will be useful to you.

What is a Laser TV?

Laser TV is a fourth-generation TV that uses laser light source and is equipped with a professional anti-glare gain screen. It can watch radio and television programs and on-demand Internet content. The laser TV image is reflected by the screen into the human eye. According to ophthalmologists and evaluations, laser TV products are harmless to the naked eye. The screen has no electromagnetic radiation, is eye-protecting, healthy, and comfortable, and is 20% more comfortable than paper reading.

The laser TV image is reflected by the screen and enters the human eye to form an image. The principle of laser TV is to use DLP technology to display images. Take the DMD chip as an example. The DMD chip is the core imaging component of the laser TV. It arranges millions of small mirrors, and each small mirror can flip in the positive and negative directions at a frequency of tens of thousands of times per second. The light is reflected by these small mirrors and directly forms an image on the screen. Due to the visual inertia of the human eye, the three primary colors that are rotated at high speed on the same pixel point will be mixed and superimposed to form color.

LCD TV resolution problem

The resolution of LCD TVs is generally set at the factory and does not require user adjustment.

1. The current common LCD TV screen resolution is generally 1366 by 768 pixels. The resolution of full HD LCD TV can reach 1920 by 1080 pixels, and the resolution of ultra HD 4K TV can even reach 3840 by 2160 pixels.

2. Resolution is one of the important parameters for LCD TVs. Generally, for screens of the same material and size, the higher the resolution, the clearer and more delicate the displayed image will be.

3. Resolution in the general concept is a physical structure, that is, a characteristic that cannot be changed once it is generated. In order to distinguish it, we usually call the resolution determined by this unique structure the physical resolution. The resolution of an LCD TV is set before leaving the factory. Usually, the best resolution of the TV is used, which is also the maximum resolution. The image display effect is the best, and the user does not need to set it separately.

The difference between LCD TV and plasma TV

Plasma TV is a display technology that uses inert gas discharge. It uses plasma tubes as light-emitting devices. Each pixel corresponds to a plasma tube, and the plasma tubes that emit light are evenly distributed on the screen. In this way, the center and edge of the displayed image are completely consistent, and there will be no distortion, achieving a truly pure plane. It also achieves high brightness and contrast. The design of the three primary colors sharing the same plasma tube also avoids focusing and convergence problems, and can achieve very clear images.

The liquid crystal display in LCD TV is a transmissive display technology, which uses thin film technology to make transistor electrodes, and uses scanning to actively control the opening and closing of display points, thereby controlling the arrangement of liquid crystal molecules, and then changing the light shielding and light transmission state to display images. Liquid crystal display itself does not emit light and requires a backlight source, so the brightness depends on the light transmission efficiency of the backlight source and the liquid crystal itself. Therefore, it is more difficult for LCD TVs to achieve high brightness and contrast than plasma TVs, and there are also problems with response time and viewing angle. However, the recent progress of LCD display technology is quite amazing.

Is it better to ship a TV set by Shunfeng or Debang?

1. If you have the original packaging of the TV, it is recommended to send it by SF Express;

2. If the TV series is not in its original packaging, it is recommended to send it by Deppon Express;

3. SF Express can provide high-level door-to-door express services in 31 provinces, municipalities, Hong Kong, Macao and Taiwan. It adopts standard pricing and standard operating procedures, and each link is shipped, transferred and delivered at the fastest speed, and relatively standard commitments are made to customers.
