LED backlight TV revenue during the New Year's Day will exceed the CCFL model

Stimulated by the rising share of first-line TV manufacturers, many domestic manufacturers are actively developing more competitive high-end products. According to industry sources, LED backlight LCD TV sales revenue during the New Year's Day will exceed CCFL backlight models.

According to data released by the research company, the scale of domestic 3D TV is expected to be 500,000 units this year, accounting for 0.5% of the total flat-panel TV. However, it will be the focus of market competition next year. At present, some domestic manufacturers have reduced the price of 42-inch 3D TV to less than 10,000 yuan.

Affected by the surge in domestic TV demand in recent years, the outside world has expected that the domestic LCD TV market demand will reach 39 million units this year, but the real situation has not reached expectations, and the third quarter data shows that the domestic LCD TV market shipments are still falling. 2%, the US market has increased by 3%.

During the domestic manufacturer's 11th period, in order to stimulate demand and increase market share, the LED backlight TV model was promoted, which increased the share of LED backlight models to a certain extent, which accounted for 40% of the national TV sales.

3D will become the focus of competition among domestic manufacturers next year. At present, Hisense has launched four 3D TVs, three Changhong and TCL, and Konka has also released 55-inch and 72-inch 3D models. Skyworth plans to come up with its own this month. 3D TV.

Skyworth said that the current mainstream 3D TV price is 2-2.5 times that of LCD TV. Their goal is to reduce this price gap to 1.5 times. With the approach of New Year's Day and the Spring Festival, first-line TV manufacturers and domestic companies are preparing for holiday promotion, and low-priced 3D TV is expected to appear on the market soon.

High Frequency AC Power Supplies

High Frequency Variable frequency AC power supply converts AC electric to pure sine waveform by through AC – DC – AC conversion, which is different from variable frequency speed controller and common AC voltage regulator.

Variable frequency power supply is mainly used to convert existing AC power network supply to stable and pure sine power supply with regulated required frequency. The features of ideal AC power supply are stable frequency, stable voltage, zero internal resistance and Sine wave form (without distortion). Variable frequency power supply is close to the ideal AC power supply, so the developed countries more frequently use variable frequency power supply as the standard supply to provide the most excellent powering environment for electrical equipment and to easily evaluate their technical performance. Major types of variable frequency power supply are: Linear Amplification and PWM Switching

VFP-H series variable frequency power supply is manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation.

Comparing to traditional frequency inverter power supply, our inverter power supply removes the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC inverter power supply could give stable AC output with prefect output precision.
Because, our new technology does not need transformer for conversion and isolation, the power supply size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
