>> Achieve full-screen LTPS LCD "inexpensive" 20th,Nov,2017
The third quarter is the smart phone industry shipping season, the current millet MIX2, Samsung S8, Sharp new machine AQUOSS2 and other full screen mobile phones to accelerate penetration of the market. If the new Apple machine is available in September as scheduled, the domestic mobile terminal brands will validate the new aircraft program. For example, Huawei, Xiaomi, OPPO, VIVO and Jinli will follow the strategy and actively deploy the new full-screen machine. It is believed that the order will be quickly implemented Panel manufacturers hands.
According to the statistics of the sun big data statistics, 2017 full screen smartphone production or will reach 165 million, is expected to heavy volume in Q4. Among them, if the yield of the production process as well as merchants stockpile also included in the calculation, the panel required for a full screen smartphone In addition to the 90 million AMOLED panels used by Samsung and Apple, LCD panel shipments are expected to reach 174 million, Mainly for the domestic brand manufacturers.
At this juncture, the demand for full screen LCD panels will help improve the overall LTPS LCD supply and demand. The LTPS LCD panel will have a market increase. There are two main reasons, first, AMOLED domestic production capacity is limited, and second, LTPS LCD used in a full screen more advantages than a-Si LCD.
In the process, LTPS process, the semiconductor size of the wiring can be done within 10um size, which has no effect on the curing glue, so do not need to avoid the safe distance, LTPS screen frame can be done 500-600μm. However, in the a-Si process, the part of the semiconductor device in the wiring line has a size of about 100 μm, which affects the sealant curing. Therefore, the safe distance between the sealant and the wiring semiconductor device needs to be 100 μm or more, and after the coating precision is limited , The sealant itself should be at least more than 500um is more safe and have the possibility of mass production, the final cell phone glass cutting edge accuracy of about 50-100um or so, a-Si screen border about 700-800μm . So, LTPS can be made narrower than a-Si for narrow bezels.
At the price level, due to a number of manufacturers have closed a-Si LCD production line, a-Si LCD panel supply and demand from loose to tight, the overall price began to soar, the market expects Q3 a-Si cell phone panel prices are expected to rise 10 - 20%. As LTPS LCD panels continue to increase in capacity, Q3's LTPS LCD panels are still expected to be in oversupply. Since the beginning of 2017, LTPS LCD prices have dropped 21%. Currently, it is estimated that prices will decline, but the decline will be reduced, slowing down, will gradually reduce the spread of a-Si LCD. This means that, if the LTPS LCD prices down further, a-Si price advantage is gradually lost, LTPS penetration of a-Si speed imminent. If the Q4 full-screen mobile phone to achieve heavy volume, LTPS LCD is expected to achieve supply and demand balance.
