The replacement of new technologies has never been smooth sailing.
Right now, LG is cooperating with Changhong, Konka and Skyworth to jointly promote OLED TV. Other domestic manufacturers have set up another mountain and launched ULED and QLED TVs to compete with them.
Recently, TCL Group announced that it has developed QLED TV, which is expected to be launched in September this year. Not long ago, Hisense also launched ULED TV.
In fact, the two companies have a common purpose in launching these dazzling new TVs, which is to call the recently hot OLED TV.
Liang Qichun, assistant president of TCL Group and general manager of brand management center, said that QLED display technology is developed by TCL's Huaxing Optoelectronics itself. It is superior to OLED TV in color gamut, but its cost is much lower than OLED TV, and the market grows better. .
In fact, TCL is not the first company to stand up to compete with OLED TV. Prior to this, Hisense also launched a TV with ULED display technology, and used it as the new TV product this year. Zhou Houjian, chairman of Hisense Group, also said at the press conference that the current hot OLED display technology will eventually be replaced by laser projection technology.
Liu Buchen, an expert in the home appliance industry, said that from a positive perspective, Chinese companies have now dared to try and dare to call out their own industrial claims. "And in the past, what other people do and what we do, there is no point in our own opinion."
Liu Wei, general manager of Aowei Consulting Tablets Division, said that these moves are based on strategic cooperation, because now only domestic operators, Skyworth, Konka and Changhong can get LGDisplay OLED panels, while Hisense and TCL have never The cooperation has been done, so the introduction of QLED and ULED at this time can be regarded as a response before the arrival of OLED.
In fact, there is a big background for domestic manufacturers to call OLED TVs. This year's color TV market prospects are not optimistic. According to the forecast data of Ovi Consulting, the total retail market of color TVs in China during the May 1 promotion period (April 14 to May 4) was 4.02 million units, a year-on-year decrease of 5.9%.
Ovi Consulting believes that due to the lack of positive stimulus policies, such as energy-saving subsidy policies, this year's home appliance market competition is expected to be more intense.
Peel Mask PCB
Peel able masks are used in order to protect selected solder holes against plugging during mass soldering or to protect carbon elements and gold plated contacts during mass soldering. Peel able masks are screen printed.
Requirements
• The peelable mask must adhere sufficiently well to the PCB so that it does not peel off when handled correctly.
• It must be able to endure a two to three time soldering process without peeling off, but must remain detachable.
•After soldering of the PCB, the peelable mask must be able to be detached – preferably in one piece. In case of metallized holes, no mask
residue must be left in the drill holes or on the surface of the PCB. In the case of non-metallized drill holes, however a certain amount of residue
can remain.
• The peelable mask must be able to resist conventional solvents such as chlorinated and fluorinated hydrocarbons, isopropanol, conventional
fluxes and similar.
• Particular requirements: The roughness U of the edge of the mask can be 0,5 mm from the tip to the base (left figure
below).
