Color TV is one of the industries with the highest degree of internationalization and marketization in China. However, after the transition from CR to flat-screen TVs, China's color TV industry has fallen into the dilemma of "lack of cores and fewer screens" and has become a key resource for the industry-net import of panels. Area.

In this environment, the breakthrough route chosen by domestic companies is to concentrate industrial capital on the panel production line in an attempt to break through the industry "blockade" of panel resources on Japanese and South Korean companies. The 6th generation line of BOE Hefei was put into production in 2010, and its 8.5th generation line was officially opened in June 2011; the 6th generation line was announced in 2010; the 8.5th line has also been capped ahead of time, and the high-generation panel production line was also launched in 2010 Obtained formal approval from relevant national authorities.

Driven by the control of relevant hard indicators in the circulation market and the growth of consumer demand for environmentally-friendly products, flat-panel TV manufacturers have seen the need for future product technology to develop energy saving and environmental protection, and fierce competition in the existing flat-screen TV market Under the circumstances, the increased cost of environmentally friendly products will undoubtedly reduce the competitive advantage of the whole product in terms of price.

Although at the current stage of the market, there are still few manufacturers of flat-screen TVs that have energy-saving, environmentally-friendly, and power-consumption-reducing products, and the uneven supply and demand phenomenon has also opened up a fast-growing China's flat-screen TV industry. Consumption gap of consumable flat-panel products, but energy-saving and environmentally-friendly TV products will become the mainstream products of the flat-panel market in China in the future, and will become the necessary functions of future flat-panel TV products and the technological competition points of many manufacturing enterprises.

LCD LCD TV is mainly used

3D home product display is a new and practical modern publicity display form. Digital virtual technology is used to realistically simulate home products. Three-dimensional production and post-processing software are used to simulate the appearance of the product to achieve real, three-dimensional and intuitive display effects.

With the rapid development of the Internet, 3D technology has gradually risen and is used in various industries.

In 2010, the total global flat-panel TV market shipments reached 206.18 million units, an increase of 31% from the previous year. One-year growth of 31% and 29%. In 2010, the total shipments of LED and LCD TVs reached 37.5 million units, and successfully entered the mainstream market. The flat-panel TV market is expected to reach 230 million units in 2011, an increase of 13% over 2010. In 2009, China produced approximately 67.8 million flat-screen TVs, ranking first in the world. In 2010, China's flat-panel TV production reached 80 million units, reaching 80% of China's TV production. 2010 was hailed as the fastest year for the popularity of flat-panel TVs, mainly reflected in its product sales. In 2010, flat-panel TV sales reached 35 million units, of which LED TV demand reached 4 million units throughout the year, and sales accounted for 13% of flat-panel TV cost requirements. In 2011, with the clear definition of energy efficiency levels and the full implementation of energy efficiency labels, LED TVs will The total replacement of CCFL LCD TVs accounted for 80%. The national standard for energy efficiency of flat-panel TVs, which was officially implemented on December 1, 2010, ended after a three-month buffer period to the end of March. Beginning March 1, 2011, flat-panel TVs that do not meet energy-saving standards will be banned from selling on the market. Because the minimum entry threshold for level 3 is not high, and non-compliant products have undergone several rounds of clearance in 2010, flat-panel TVs sold on the market at this stage can easily meet the standards, and have no impact on the color TV market.

In December 2007, Shandong, Henan, and Sichuan provinces conducted fiscal subsidies for home appliances to the countryside. The farmers in the three provinces purchased color TVs, refrigerators, and mobile phones in three categories. Based on the export tax rebate rate, they were given a financial subsidy of 13% of the sales price. , Has reached the goal of stimulating rural consumption, hugging farmers to improve the quality of life, reducing trade surpluses, and promoting the healthy development of the home appliance industry. After 2008, the number of home appliances going to the countryside has gradually increased and expanded to the whole country. At the same time, the number of home appliances going to the countryside has gradually increased, including TVs, washing machines, refrigerators (freezers), mobile phones, air conditioners, computers, water heaters, microwave ovens, and induction cookers. , Electric bicycles and other products. Home appliances going to the countryside has greatly promoted China's color TV industry. In 2009,

1. Contrast: At present, the contrast of plasma is mostly 3000: 1, 4000: 1 and 5000: 1, even as high as 10000: 1, and the contrast of LCD TV is basically between 400: 1-1200: 1. In a very adequate environment such as a store, the LCD TV screen will be brighter than the plasma. However, in a relatively dark environment at home, the LCD will be more dazzling. If you lower the brightness, you will lose the image layering and dark screen. detail. Compared with plasma, the picture is softer, clearer and more transparent.

2. Viewing angle: Due to the different light emitting principles, although plasma and LCD TVs can reach 170 degrees of viewing angle, when LCD TVs are viewed at large deflection angles, the screen will have a color cast phenomenon, but plasma does not have this problem. Therefore, when the whole family watches together or the living room area is large, plasma TV is more suitable.

3. Dynamic sharpness / response speed: Dynamic sharpness refers to the visual sharpness felt by the human eye when watching a moving picture. The response speed is the response time of the TV circuit to the processing of moving pictures. Plasma has excellent dynamic sharpness and extremely fast response speed (less than 1ms). Whether it is a stationary landscape picture or a fast sports picture, it can be clearly displayed without tailing. The response speed of the liquid crystal is between 8-25ms. When playing low-speed moving pictures, the picture quality is more delicate than that of plasma. However, dynamic picture performance is far worse than that of plasma. When playing fast-moving pictures, it is prone to smearing and image overlap. This causes visual fatigue and affects vision health.

4. Power consumption: According to product data, the power of a 42-inch plasma is generally about 350W, which is higher than the general power of a liquid crystal of the same size. However, due to different light emitting principles, the power consumption of plasma and liquid crystal on different screens is also different. Plasma is the self-emission of screen pixels, and the power consumption changes with the brightness of the screen. 350W refers to its power at peak brightness. No matter how the screen changes, the backlight of the liquid crystal always emits light, so the power consumption is fixed. For example, when playing a variety show with a bright screen, the power consumption of plasma is large; while in a normal brightness screen (news, sports events, TV series, etc.), plasma is almost the same as liquid crystal; Power consumption is lower than LCD.

5. Service life: At this stage, both plasma and LCD TVs can reach a display life of 60,000 hours (the display capacity is reduced by 50%), but in fact after 16,000 hours, both plasma and LCD TVs will have a certain screen display capacity attenuation and attenuation range. According to the actual use situation, it is about 10%-40%.

6. Screen size selection

Large size is an inevitable development trend of flat-screen TVs, but how big is the reasonable size to choose? The most taboo intention to buy a TV is that the bigger the better. Everyone buys 42-inch ones, so I also buy 42-inch ones, otherwise I feel "outdated".

It is most reasonable to choose a size based on the size of your personal housing space. Of course, the space size mentioned here mainly refers to the visible distance (the distance between the human eye and the TV screen). Television needs to be watched for a long time. A moment's make-up or awkwardness will cause long-term visual fatigue. As time goes by, it will affect physical health and should not be slighted.

The LCD panel can be divided into hard screen and soft screen according to the display technology. Soft screens mainly refer to VA panels, while hard screens are well-known IPS panels. At this stage, the manufacturers of two types of panels mainly include: IPS hard screen manufacturers: LPL, IPS Alpha;

Samsung Electronics' PVA (Patterned Vertical Alignment) technology belongs to the category of VA technology. It is the successor and developer of MVA technology. Its comprehensive quality has surpassed the latter comprehensively, and the improved S-PVA can already go hand in hand with P-MVA, obtain extremely wide viewing angle and faster and faster response time. PVA uses transparent ITO electrodes to replace the protrusions of the liquid crystal layer in MVA. Transparent electrodes can obtain a better aperture ratio and minimize the waste of backlight.

Samsung s PVA mode wide viewing angle technology is widely used by Japanese and American manufacturers due to its strong production capacity and stable quality control system. At this stage, PVA technology is widely used in high-end LCD monitors or LCD TVs. The VA panel is also a soft screen. Similar water marks will appear when you gently scratch it with your hand.

In all aspects of performance, IPS hard screen has fast response speed, excellent moving picture, stable picture quality, large viewing angle, and good cost control. The biggest feature of the IPS panel is that its two poles are on the same side, unlike other LCD mode electrodes, which are arranged in three dimensions on the upper and lower sides. However, because the electrodes are on the same plane, the liquid crystal molecules are always parallel to the screen regardless of the state, which will reduce the aperture ratio and reduce the light transmittance. Therefore, IPS applications will require more backlights on LCD TVs. To a certain extent, the power consumption is larger. There is also an S-IPS panel that is an improved version of IPS.
