SuperC-Touch’s 3rd patent for advanced in-cell touch panel
open to make sales
Name: A Touch display panel with metal lines connected to touch sensor electrodes on V com layer
Price: 5,000,000. USD
Description:
Case of the present invention and the invention (TW 201031961) of Apple iPhone 5 with the same purpose, not only has its advantages, but also to avoid the iPhone 5 in-cell panel is not easy to produce the main drawback; Apple's invention is applicable to FFS or IPS screen, SuperC-Touch patent for TFT LCD screen, Apple applied to pattern the LCD Array V com layer on the substrate glass as Sensor, SuperC-Touch put LCD V com layer on color filter which is patterned as Sensor. Apple used the mutual capacitance structure, SuperC-Touch with the point self-capacitance structure, Apple's invention requires time-sharing operation, so the reaction time slows down at report rate decreased, the reaction will be too late for mid and large size panel, only could be applied on the small size panel; SuperC-Touch’s patent may detect touch and display processing operations at the same time, no report rate decrease, estimates can be applied to up to 23” in-cell touch display panels. Apple in cell manufacturing process is very complex so the relatively poor yield; SuperC-Touch’s manufacturing process is simple and yield increase. Apple used IPS, FFS screen which its Vcom layer is on TFT array glass, so its sensors could not be isolated from the LCD drive signals cause electromagnetic interference, Many manufacturers coated an ITO layer on the color filter glass that used to isolate the electromagnetic waves in order to solve problems of electromagnetic detection requirements of different nation. Once you add this layer of ITO after, Apple in cell touch wouldn’t be used, so many of the LCD manufacturers could not join Apple in cell supply chain. In SuperC-Touch’s patent, the V com layer on TFT LCD color filter itself can be used to isolate the electromagnetic wave, so the ITO layer is not necessary。
In addition to these differences above, the two have in common is the touch IC's requirements are not high, manufacturers can provide touch IC at least the following, Apple、Synaptics、Atmel、Cypress、Silicon lab、Microchip、STMicro、Elan、EETI、FocalTech、GOODIX,etc. You do not need to wait until SuperC-Touch invented the "perturbation resonance" technology touch IC developed, can immediately commercialization. This SuperC-Touch’s patent is the best weapon to seize the market of mainland China
SUMMARY OF THE INVENTION
The object of the present invention is to provide an in-cell touch display panel system with metal lines connected to sensing electrodes in V com layer, comprising a first and a second substrate, a liquid crystal layer, a light-shielding layer, a sensing electrode layer, an insulating layer, and a sensing electrode routing layer. Shielding layer constituted by a plurality of shading lines. Sensing electrode’s routing layer is located on the surface of the light-shielding layer by a plurality of conductor wires. The insulating layer is located on the surface of the sensing electrode routing layer which is faced to the liquid crystal layer. Sensing electrode layer is located on the surface of insulating layer with respect to one surface of the liquid crystal layer, by the common electrode (V com) is patterned to form a plurality of transparent sensing electrodes. Each sensing electrode has at least one conductor lines connected thereto, the plurality of the routing positions of the conductor lines were based on the plurality of the light shielding lines and set up corresponding to the positions.
