The cost of touch ultrabooks is expected to be significantly reduced. Dialog has recently released an innovative optical touch chip and module reference design. This solution can realize multi-touch through infrared planar scattering detection (PSD) technology without the use of ITO conductive film In general, large and medium-sized projected capacitive touch modules, the cost can be reduced by more than 40%, and the assembly yield is also significantly improved, which helps accelerate the decline in the price of touch ultrabooks. Mark Tyndall, vice president of global strategy development at Dialog, said that Microsoft, Intel and PC brands have high hopes for deformable laptops with multi-touch capabilities. However, new products must simultaneously meet the three major requirements of multi-touch, thin and light design and low additional cost. At present, the industry still cannot find suitable touch solutions, including resistive, image and sonic touch technologies, which have been early encountered by brands. Eliminated by the factory; even if the projected capacitive touch that is quite mature in mobile phones and tablets is used, it still faces the problems of excessive cost of ITO materials after enlargement in size, poor yield and poor performance. With this in mind, Dialog and Flatfrog, which focuses on large and medium-sized touch solutions, combined with SmartWave and PSD touch technology patents of both parties, have developed a new-generation optical touch solution that does not require an ITO conductive layer, which is expected to break through the touch-type ultrabook Or the development status of AIO computer prices is high. At present, Dialog has used a 65-nanometer (nm) process to create a control chip for this touch technology, and recently obtained Windows 8 certification, which will be introduced into mass production in the third quarter of this year. Tyndall emphasized that the new optical touch solution can meet the design of 11-36-inch edge-to-edge screen, and can directly detect the surface pressure of the panel and the change of the light source signal of the internal infrared light-emitting diode (LED). There is no need to import any sensing materials or components, which affects the module cost and transmittance. Due to its simple system architecture, low price, and support for up to forty-point touch, the solution is expected to gradually replace the complex and expensive projected capacitive touch solution with a sensing layer design, and become the mainstream technology for large and medium-sized touch panels . It is reported that at this stage, Dialog, PC brand manufacturers and panel makers are stepping up the development of 14-inch optical touch notebook samples; compared with projected capacitive touch products of the same specifications, the development cost per inch has dropped significantly by 40%; in the future, more than 20 inches After the display or AIO computer is successively replaced with optical touch, the saved materials and the cost of process optimization will be more obvious. Tyndall also revealed that optical touch PCs are expected to be released in large quantities in the spring of 2014, accounting for 40% of the total touch PC shipments in 2 years. In fact, in the US $ 300 million Ultrabook Fund, Intel has also allocated about US $ 10 million to invest in Flatfrog and Dialog ’s optical multi-touch technology, which will accelerate the upstream and downstream supply of chips, modules and systems for new solutions The chain takes shape and promotes the decline in the average price of touch PCs, entering the mainstream price band below $ 600.
