This year's LED display technology seems to be updated very fast, liquid crystal display (LCD) already withdrew from the historical stage, the plasma is no longer the latest display technology. 4 k, OLED, IGZO, sapphire, etc. These nouns begin to take turns to appear in the display industry, refresh the knowledge of the latest display technology. Small make up today about the inventory of some of the latest display technology.
As the news of iPhone6, sapphire screen also gradually known by people. But what most people do not understand the sapphire screen, even when some people ask what gems can be used to do the screen? In fact, in fact, the sapphire is not display medium, but with the glass, the material, the stroke because of the high hardness of sapphire, the traditional hard hardly leave scratches, so sapphire glass than the gorilla glass has more advantages, more protection of mobile phone. But sapphire price is more expensive, the gorilla glass cost $44, estimate the price of $280 and sapphire glass, which makes the high price of mobile phone products, so there will be a limited number of messages, estimates that apple will use this material on high-end products.
China, Japan and South Korea LTPS scramble up the waves
Compared to be known as sapphire screen, LTPS impression to people is a stranger. LTPS is a kind of low
temperature polycrystalline silicon technology, it can improve the resolution of the LCD, the drive device of LCD pixels. Compared to the conventional amorphous silicon drive, LTPS low-temperature polysilicon, has smaller volume, but more powerful energy, so you can in the same size screen layout more pixels, the high-end mobile phone and tablet is used the drive way, so as to improve the resolution of the screen, such as we are familiar with apple Retina concept, is the use of this technology to realize.
Using the technology of display screen as the main parts of intelligent device, its main characteristic is to be able to significantly improve the profitability of liquid crystal display screen, which makes many manufacturers choose this technology to realize profits. For example the JDI is dedicated to producing the panel and establish the enterprise, its raw products of LTPS panel used in a variety of high-end mobile phone, including the international manufacturers such as apple products, including a line such as huawei, meizu domestic enterprises, in addition, Japan's sharp is also an important competitor LTPS panel.
Low-power LED screen is just legend
Leds don't have to do more, he is already known to everyone. We often say that the LED screen is actually mostly refers to the LED backlit display, but the real LED is mostly used for lighting, although LED to imaging because of its large size is not suitable for production of the display. The LED screen, we see when shopping is the best witness, LED directly to the imaging its far effect is good, but almost is a bit miserably mesh endure to see. Recently it is reported that the apple will wear equipment using LED screen, low power consumption looks interesting.
LED pixel size is small, but the volume of a luminous firmware itself and it is difficult to narrow, so the words of
the application to a wearable device pixel small to can only be seen with a microscope, under this premise will install 6 LED module, the difficulty was palpable, the LED backlight display also is not each pixel is equipped with a white light, but the pattern of light guide plate, LED lights with the method of offset, just put out the light uniformity, so from a technical perspective, this low-power LED screen is difficult, the cost is high, almost impossible to realize.
