The current price of laser TV is relatively expensive. Although there are products less than 10,000 yuan now, the average price is about 15,000 yuan even if the price of anti-light curtain is included.

Compared with the LCD TV that consumers are familiar with, this price is not so close to the people. However, laser TV is on the rise. Although the development speed is very fast, there are still some imperfections. Today we will talk about these issues, and hope that laser TV will have a better development in 2018 at the beginning of the new year.

The brightness problem is currently not perfect

The brightness of laser TV is always the core. At the same time, the laser light source is also one of the main costs, and the brightness of the product directly determines the price of the product. At present, the brightness performance of many laser TVs less than 10,000 yuan is not satisfactory, and the main reason is that the cost is saved in the light source.

As for the more expensive laser TVs, according to our measured data at the end of 2017, the ANSI brightness of laser TVs averages 2200 ANSI lumens. A better product can reach 3000 ANSI lumens.

Such data can be used at night. But if it is applied during the day, the brightness performance is still almost meaningless.

In addition, we should note that many laser TVs now support HDR functions, and high-end users value HDR functions very seriously. This function requires high brightness to have amazing effects. Therefore, the brightness performance of laser TV is still somewhat lacking at present.

The author believes that the measured ANSI brightness of the laser TV should be above 3000 ANSI lumens, and the flagship product should be above 4000 ANSI lumens, so that it can meet various home environments.

Contrast problem is the root of delicate picture

The laser TV uses a reflective ultra-short focal lens, so it can achieve the effect of a 100-inch screen within 40 cm.

But it is precisely because of this lens that the contrast performance of laser TVs is not so good. In the laser TV Hengping at the end of 2017, we found that most of the laser TV ANSI contrast ratios are basically below 200:1.

Generally speaking, the ANSI contrast of ordinary home projectors that are front projection is above 200:1. This critical value is also an important criterion for us to judge the contrast of the projector.

200:1 or more is an excellent level, and below this value, it can only be a good level. If it is less than 100:1, obviously the ANSI contrast performance of this product is not so ideal.

The ANSI contrast performance of many laser TVs is not particularly good, but this is not a technical problem.

Because under current conditions, some products have an ANSI contrast ratio of more than 200:1. This indicator has a great impact on users. If the picture is not sharp, the fineness of the picture is impossible to talk about.

Therefore, the author's opinion is that the laser TV should focus on adjusting and optimizing the ANSI contrast of the product, so that with the anti-light curtain, the user can see the delicate and sharp picture.

The details of the installation problem should not be sloppy

There are also many problems with the installation of laser TVs: the first is the problem of unprofessionalism. The installation teams used by many brands are improvised without professional training.

The installation process is long, and the installation effect lacks a unified standard, which brings a bad experience to customers. After all, laser TV is a relatively expensive product, and consumers want a first-class experience.

The second is the troublesome problem for users to maintain after installation. For example, some laser TVs support manual focus, but consumers sometimes cannot find an accurate focus point by using manual focus, and the critical point of electric focus is also blurred.

And it is worth noting that the position of the laser TV is not able to move at all. Once it is moved during use, there will be a problem that the picture and the anti-light curtain cannot fit together.

This problem is not easy to solve, even a professional installer takes a long time to adjust to perfection. If it is an inexperienced consumer who wants to adjust to a perfect state, it needs a lot of patience. In actual use, laser TVs are prone to movement.
