The quality of television products in our country is increasing and HDR technology is becoming more mature
The quality of TV products in 2016 has been greatly improved compared to 2015, and the HDR (High Dynamic Range) technology has become more mature. However, the display quality of the products of various companies is uneven.
Last year, the quality of China’s TV products has greatly improved. Engineers of the Ministry of Industry and Information Technology’s Digital TV Standard Conformance Testing Center introduced the 2016 digital television display test at the forum. In 2016, the National Digital Audio, Video and Multimedia Product Quality Supervision and Inspection Center completed nearly 60 TV sets. The display inspection of the products covers companies such as Changhong, TCL, Skyworth, Hisense, LeTV, Hass, LG, Samsung, Sony, Sharp, and Storm.
Among them, the SDR (standard dynamic range) test results show that 5 of the 22 samples did not meet the technical requirements of the SJ/T digital TV liquid crystal display general specification standard, accounting for 22.7% of the total. For "brightness view."
China Economic Net reporter learned that the 2015 non-compliance projects also included “brightness†and “contrastâ€. In the 2016 test samples, the test results of these two items were far beyond the standard requirements. The viewing angle "detection results can reach the detection limit of the testing equipment. At the same time, the test samples in the second half of 2016 can meet and greatly exceed the standard requirements, and have improved product performance in the first half of the year.
HDR technology is becoming more and more mature. The quality is still uneven. The detection of digital TV displays in 2016 shows that the HDR technology has become more mature. In the first half of 2016, most prototypes require repeated debugging and retesting to achieve the final CESI/TS 008-2016 HDR display authentication technology. Specification technical requirements, but in the second half of the year, most prototypes can be tested at one time.
According to statistics, in 2016, most of the new models launched by various companies allegedly carry HDR technology. There are about 70 models on the market selling HDR TVs, but the actual quality of the various displays is uneven. According to the test results, according to the technical requirements of the CESI/TS 008-2016 HDR display certification technical specification, there are 27 samples sent for HDR1.0 detection, 5 have not passed the test, and 9 samples for HDR2.0 detection are passed. Testing. Projects that do not meet the standards mainly include peak brightness is not high enough, black brightness is not low enough, and the dynamic range is not large enough to meet the brightness requirements necessary for HDR technology.
In response to this, the Ministry of Industry and Information Technology Digital TV Standard Compliance Testing Center recommends that consumers be universally informed about digital television and interpret the meaning of quality-related marketing slogans, such as: resolution, surface, OLED, quantum dots, etc., so that consumers can truly Rational consumption, while also the performance evaluation of television products should be organized to organize companies to carry out voluntary standards compliance testing, and promote enterprise control of product quality, improve the overall level of the industry.
The center also proposes to establish a complete subjective evaluation system for television display quality, combined with objective optical detection, to avoid the situation where television sets have objective indicators that are ideal but display television screens.
