Mature market: touch panel encounters fierce price war

according to the observation of npddisplaysearch, a market research institution, 2013 was a quite shocking year for Taiwan's touch panel industry, which was greatly impacted by the fierce competition from the touch panel industry in Chinese Mainland. With the high growth of the application market for many years, the growth of intelligent demand is flat, while the tablet computer market is growing rapidly, but it is about to mature. Due to the maturity of the market and the fierce price competition of terminal products, the touch panel Market of smart and tablet computers is facing a fierce price war

npddisplaysearch said that if the demand for notebook touch panels can be realized in 2013, Taiwan's touch panel industry will have a new growth opportunity to replace the lost importance in Apple's supply chain. However, it backfired. At present, what can really create a lot of demand for touch panels is to return to smart and tablet computers. However, competition always brings innovation. In addition to touch module manufacturers, panel manufacturers in Taiwan continue to show their interest in integrating touch and LCD panels

among the innovations proposed by Taiwanese manufacturers in 2013, AUO proposed the embeddedtouchpanel (ETP) in the first quarter of 2013, while Innolux announced the adoption of innotouch with Elan photoelectric chip scheme in the second quarter, emphasizing that the product is lighter and thinner and the price is more people-friendly. The formation of these two solutions is related to the evolution of Microsoft's touch design specification for windows8, and is also to solve the problem of high cost of edge-to-edge OGS touch panel

in order to cater to the low price trend of the market, TPK, a leading manufacturer, also announced the launch of low price solutions in August 2013. In addition, in the second quarter, qunchuang optoelectronics also began to launch the integrated scheme (TOD, touchondisplay) with embedded on-cell, and targeted the smart market

AU Optronics began to produce embedded on cell touch panels in about 2009, which are provided to Samsung's digital cameras and Dell's intelligent use; The touch sensor structure adopts sito structure and is produced by cando (now Dahong). For the on cell touch panel with sito structure, in addition to the color filter, there is also a touch sensor manufacturing process. In addition to the cost allocation of the mask, the final straight through yield will also be a factor affecting the cost

based on factors such as cost, yield and customer introduction, the most successful on-cell touch panel is samsungdisplay, which is supported by a strong downstream brand. Samsungdisplay uses AMOLED instead of LCD. Samsungdisplay AMOLED adopts RGB coating and has no filter, so the glazing is very simple, so it is very suitable for on-cell structure. In 2013, qunchuang optoelectronics adopted the Synaptics chip scheme and introduced about 4.5-inch 720p t od after the service life of the parts

the new generation todon celllcd has made rapid progress in technology in various industries. The importance of friction and wear testing machine for various industries is becoming more and more obvious. The sensor pattern of "single layer and multi points" is adopted, commonly known as Caterpillar pattern; Most touch chip suppliers have the design of caterpillarpattern, but in order to avoid patent problems, there are some differences in patterns between them. The single-layer multipoint pattern was first introduced into the GF structure around 2012 in order to save the demand for an ITO film, and the round specimen 1 is generally tested in the V-shaped groove to replace the GFF structure

npddisplaysearch points out that although ITO films may not necessarily adopt sito structure like glass substrates, due to equipment and yield, GFF structure has always been the main structure. GF triangle structure is not really multi touch, so it is mostly used in lower order. In 2013, the single-layer multi-point pattern moved from GF structure to on-celllcd, mainly to reduce the number of masks in the past sito structure and improve the process yield

compared with the sito structure, the single-layer multipoint pattern does not need to be insulated on the bridge between XY electrodes (there is a photoresist under the bridge), so the severity of yellow light equipment and yield is improved. However, the single-layer multipoint pattern still needs not to be touched between XY electrodes, because this is the basic principle of projection capacitance (self capacitance). The electrode segments cut into many segments will not cross with the other electrode (so no insulation is required), but additional leads are required to connect them

the larger the panel, the higher the touch resolution (xychannels) and the more leads are required. Too many leads in the touch area may lead to the decrease of induction sensitivity, so the single-layer multipoint is currently limited to less than 5 inches. At present, the 4.5-inch 720p TOD has been introduced by brands (such as Coolpad and Motorola), and Taiwan factories such as Huaying and Caijing have planned to introduce it

generally, the so-called OGS (oneglasssolution) refers to the full plane surface glass design, and the fitting can be opticalbonding or airbonding. The manufacturing process of OGS is divided into sheettype and piecetype; The former is more productive, but in the surface glass processing stage, due to the plated sensor circuit on the surface, additional attention must be paid to the processing process

npddisplaysearch indicates that the blockbuster process has almost become the standard of OGS in notebook computer applications. In the first half of 2013, since the cost of OGS was still high (about $50 to $70, excluding full fit), low-cost ETP and innotouch were proposed. Although the cost of OGS decreased significantly in the second half of 2013 (about $30~40), the low-cost solution still has considerable attraction for notebook brands
