We only know that there are LCD TVs, but do you know that LCD TV panels are actually using different materials? Today, we look at the difference between an ISP hard-screen panel and an LED panel.
What is an IPS hard screen?
IPS (In-Plane Switching, planar conversion) hard screen technology is currently the world's most advanced LCD panel technology. Among the companies that own this technology and achieve mass production, South Korea’s LG Display Corporation is the largest company with a leading technology level. LG Display's 7.5-generation production line has been mass-produced in January 2006, with a monthly production capacity of 150K; cutting technology is mature, and the yield rate is extremely high, reaching 95%. A hard screen is a film with a layer of resin attached to the surface, just as people wear glasses.
The so-called hard-screen product is a layer of transparent resin material that protects the outer film on the LCD screen. The prominent feature of the hard screen is that the screen has a certain degree of stability. Gently prying it with your fingers will not show any obvious shadows, which is good for screen protection, but the sticking process must be good enough. Can not only completely eliminate the liquid crystal display in the external pressure when the emergence of the blur and the water pattern diffusion phenomenon, but the picture quality is more delicate, the viewing angle is almost 180 degrees, in the display of dynamic images, the improvement of color stability and layering Also greatly improved, but also to ensure the clarity of image display.
the difference:
1, ISP hard screen panel without watermark, more stable - hard screen squeeze anhydrous lines, stable and more stable image quality, IPS mode without spots - because of a stable and strong liquid crystal structure, LED panel will touch A great afterimage phenomenon.
2, ISP hard-screen panel 178 degrees wide viewing angle, panoramic viewing more exciting; follow S-IPS's unique liquid crystal molecular level conversion technology allows you to enjoy the most perfect, excellent in any environment, even in the angle of 178 degrees Quality. IPS hard screen has obvious advantages over LED panel.
3, ISP hard-screen panel fast response, smoother motion picture, due to the effect of motion blur, LED panel large-scale image distortion and color changes.
4, ISP hard-screen panel ultra-high contrast, pure black level more clearly. Unlike LED panels, the change in white balance of the IPS screen in each grayscale is completely negligible. In the case of LED panels, the slender performance in low gray levels is difficult to place in the voltage origin due to the change in the brightness of the steep edges. At low gray levels, the unstable performance of the voltage value results in uneven brightness.
5. In addition, the two indicators of life and energy consumption are quite worthy of attention. According to current standards, the life span of ISP hard-screen panels is 70,000 hours, which is greater than the 60,000-hour design life of traditional LED panels. On the other hand, the ISP hard-screen panel has a further drop in power consumption compared to the soft-screen LCD, which is more energy-efficient than traditional LED panels. For example, compared with 40-inch LED panel TVs, 42-inch ISP hard-screen panel TVs, although the size is large, the average power consumption is only 220W, and the latter's average power consumption is 245W. In this way, according to the 60,000-hour lifespan of the LED panel, using a hard-screen LCD TV can save 2100 kWh.
