For TV brands or panel makers, LED-backlit TV is undoubtedly the priority of product development this year; in order to achieve the LED TV jump-type shipment growth target, manufacturers are actively looking for a stable source of LED chips, focusing on procurement and preparation. On LEDs and strips; however, WitsView believes that the supply of relatively neglected light guides and raw materials PMMA is likely to be the most serious part of the shortage of LED TV materials this year.
The light guide plate material polymethyl methacrylate (PMMA) is divided into two types: plate and particle. Generally, the former is mainly cut through the larger size monitor and TV light guide plate, while the latter is through The injection molding process is applied to NB light guide plates with high thickness requirements.
According to WitsView, the demand for PMMA in the past is almost equal to the demand for NB and Monitor panels. Due to the stability of the IT market, PMMA raw materials and sheet suppliers have always been conservative in dealing with the expansion of production. However, since last year, LED TVs with side-entry light sources have been successfully formed into the mainstream of the market. In view of the difference in optical design, the backlight module must replace the diffuser with a light guide plate, and the average TV size is much larger than that of IT products. As a result of the substantial increase in volume, PMMA naturally shifts from oversupply to tightness, and even in the future there will be a shortage of supply.
Qiu Yubin, research manager of WitsView, believes that the real supply problems of PMMA will be concentrated in the second half of this year. Although the industry has begun to try out various possible alternative materials to produce light guide plates, it seems that it is difficult to connect other materials in a short time because of the transmittance and cost considerations.
As for the gap in PMMA, will it have the biggest impact on that part of the supply chain? Qiu Yubin said that Samsung and LG, the brand manufacturers, had earlier development time. When they discovered that PMMA might be out of stock, they had already signed a supply contract with suppliers from Japan, Taiwan, South Korea and China. stable. As for the faculty panel factories such as AUO and Xinqimei, the related companies, Fuxiang and Chimei Industrial, are among the top three PMMA sheet suppliers in the world. With the support of the Group's resources, the degree of impact is expected to be More limited.
In contrast, the LED TV market is positioned as a domestic brand in the first-class theater. Although it spares no effort in mastering and preparing the LED itself, because it is at the end of the supply chain, the cooperation relationship with the upstream PMMA supplier is obviously not as good as that of the backlight module factory. In the panel factory, the mastery of the material conditions is relatively low. Once the PMMA gap is formed, causing problems with the source of the light guide plate, these brand manufacturers are bound to be interrupted in the self-organizing plan of the LED TV panel, and can only seek to purchase from outside.
According to WitsView's observation, the number of LED TV panels sold by Samsung and Sharp is not much. If the PMMA sheet and the light guide are out of stock, the actual LED TV panel on the market will become very limited. As a result, in addition to the situation that the LED TV panel may be in short supply, the panel price is also supported, so that the overall cost of the LED TV is not falling as expected. Both have cast a lot of variables for the LED TV penetration rate that was originally optimistic this year.
