Who can tell me what's the difference between FPR and GPR without blinking in 3D? Uncle Baidu can't solve it.

Since the emergence of 3D TV in the market, active shutter mode (SG) has become the main technical direction of 3D TV at present because of its high technical difficulty and low cost. At present, shutter 3D TV sets are prone to visual fatigue, which brings a shadow to the development prospect of 3D TV market. This situation is changing. August 20 10, AUO Optronics announced the mass production of the entire product line of 32-inch to 65-inch polarized 3D LCD panels. What is more striking is that on February 5, 20 10, 16, LG Display released a new generation of eye-protecting 3D TV panel "non-flashing 3D hard screen". LG Display's "non-flashing 3D hard screen" is a new generation of polarized 3D panel with upgraded technology. The 3D TV produced by this panel is not only beneficial to eye health, but also superior to the current mainstream shutter 3D TV in overall performance. It is easy to cause eye fatigue and become one of the important factors that hinder the popularization of 3D TV sets. Therefore, the technological breakthrough of eye-friendly polarized 3D panel has attracted much attention. The insiders even believe that this may change the current technical trend of 3D TV sets, and a new generation of polarized 3D display technology will become the mainstream. Technical upgrade It is understood that the traditional polarized 3D display technology has many advantages, such as no flicker, small color loss, outstanding 3D effect and large viewing angle. The matching glasses have no electronic components, no size limit, no radiation, low cost and comfortable wearing. However, due to the principle of polarization, this technology has been unable to solve the problems of halving the horizontal resolution and low brightness of the picture, so the requirements for display equipment are higher. In addition, because the polarizing layer must be installed on the outer layer of the panel, the cost of the traditional polarized 3D panel increases. Therefore, polarized 3D technology is currently mainly used in commercial occasions such as cinemas. According to LG Display, the non-flash 3D hard screen is an upgraded new technology, which is different from the traditional polarized 3D technology. LG Display calls it FPR(Film-type Patterned Retarder), that is, thin film polarized 3D technology. It retains the advantages of polarized 3D technology, with no flicker and ghost, smoother and clearer picture and large viewing angle. At the same time, the horizontal resolution and brightness are improved, which not only helps viewers get rid of eye fatigue, but also has excellent 3D imaging quality and color. According to the reporter of Electrical Appliances, the substrate of traditional polarized 3D display technology is glass, which is called GPR technology. FPR technology adds a filter film, which greatly improves the resolution and brightness. According to the data provided by LG Display, the resolution of the non-flash 3D panel of LG Display can reach 1920× 1080, which can realize full HD 3D display, and the brightness range is 2.5 ~ 3 times that of the current shutter type. In the exhibition area arranged by LG Display, electrical reporters saw a 47-inch LCD TV panel with FPR technology and an 84-inch non-flash 3D hard screen with four times the resolution of full HD (1920X 1080). "From a technical point of view, polarized 3D display technology uses the LCD panel itself more for imaging, while shutter technology relies more on glasses." A technician of LG Display explained this to the reporter of Electrical Appliances. According to reports, shutter glasses with built-in control circuits are expensive and need to be recharged or replaced regularly. FPR glasses have no electronic components, are light and easy to use, and can be interchanged. Different brands of 3D TVs using FPR technology can be seen through a pair of glasses. Shutter glasses are complex, bulky and costly, and glasses of different brands of shutter 3D TV sets cannot be interchanged. Not only that, FPR glasses use curved lenses, but also can be made into jacketed glasses and clamped on the lenses of myopia glasses. The test results of the Third Research Institute of China Electronics Technology Group show that the flicker, refresh rate, picture brightness and left-right viewing angle of FPR 3D TV are far better than those of traditional shutter 3D TV. The test results of Beijing Eye Research Institute report that "FPR 3D mode is less likely to cause visual fatigue than shutter 3D mode". Dr. James Sheedy from the Optometry Research Center of Pacific University (60 1099, USA) praised LG Display's non-flash 3D panel for not only not flashing, but also having fewer ghosts and bright pictures. The prospects are good. At present, 3D TVs launched by companies represented by Samsung and Sony all adopt shutter technology. Before 20 10 12, only TCL and LG had one product each. 201012 In early February, Skyworth launched three 3D TVs with polarized technology. It is understood that LG Display's non-flash 3D panel is used. The reporter of "Electrical Appliances" noticed that the six major domestic TV companies Skyworth, Konka, Hisense, Haier, Changhong and TCL all attended the non-flash 3D hard screen conference of LG Display, and the heads of Toshiba and Philips also congratulated LG Display through VCR, showing their support and concern for the non-flash 3D TV panel of LG Display. Konka and Hisense have made arrangements to release their own brand 3D LCD TVs with FPR technology soon. "As far as we know, more than 90% of Skyworth's new 3D TV products will use LG Display non-flash 3D panels." An industry insider revealed to the reporter of Electrical Appliances. The cost of polarized 3D TV glasses is only one tenth of that of shutter glasses. However, due to the complexity of technology, the cost of polarized 3D panel is higher than that of shutter panel. 201065438+At the beginning of February, Skyworth launched three kinds of non-flash 3D TVs, namely 42-inch, 47-inch and 55-inch. The pre-sale price ranges from 9999 yuan to 16999 yuan, which is equivalent to 1.5 times the price of ordinary LCD TVs. LG Display said that due to the technology upgrade, LG Display's non-flash 3D panel not only has superior performance, but also has a competitive price of only a quarter of that of ordinary GPR polarized 3D panel. At present, the problem of lack of 3D film sources is being solved. Many enterprises believe that the introduction of 3D TV sets that will not cause eye fatigue will help to change the current poor sales situation in the 3D TV market. Wang Zhe, vice president of Suning Appliance (002024, Share Bar), believes that this new product provides consumers with new choices and has great development prospects. Li Juntao, vice president of Gome, said that LG Display's new technology has solved the technical problems of 3D TV sets in the market, such as flicker, heavy glasses that need to be charged, signal interference or asynchronization, which is a major breakthrough. Quan Yingshou, CEO of LG Display, is quite confident about the market scale of non-flash 3D TV. According to his prediction: "In 20 1 1 year, the market demand for LCD TVs in China will be 40 million, of which 3D TVs will account for 20% and non-flash 3D TVs will account for 70% to 80%." Yang, vice president of Skyworth Group, believes that non-flash 3D technology will promote the China 3D LCD TV market to grow to more than 8 million units in 20 1 1 year.
