    • The present invention relates to a touch positioning method and system as well as a display device. Said touch positioning method is applied to an optical touch screen comprising a touch detection area, two imaging devices, a light source and a reflector, the touch detection area and its mirror image touch detection area with regards to the reflector residing within field of view of each imaging device, the method comprising: obtaining location information of touch objects based on image data of an actual touch object and its mirror image touch object with regards to said reflector acquired by said two imaging devices, said touch objects comprise said actual touch object and virtual touch object; obtaining location information of said actual touch object from the location information of said touch objects based on the mirror image relation between said actual touch object and its mirror image touch object as well as the location information of said touch detection area. The present invention may avoid the presence of “ghost images” during the positioning of more than two touch objects and accurately locate where the touch objects reside.

    • A superlattice crystal resonator having a substrate of a dielectric acoustic superlattice material, both sides of which substrate are plated with electrodes. The resonator can be a one-port resonator if the electrode on both sides is a single electrode, or it can be a two-port resonator if the electrode on one side is a single electrode and the electrode on the other side is a bipolar electrode. The superlattice crystal resonator can be used as a superlattice crystal filter, either in the form of a monolithic superlattice crystal filter formed by a two-port superlattice crystal filter, or in the form of a combined superlattice crystal filter where a number of one-port superlattice crystal resonators are interconnected in various circuitry configurations with or without other electronic components, such as capacitors, inductors, and resisters.
    • 具有介电超超晶格材料的基板的超晶格晶体谐振器,其两侧的基板都镀有电极。 如果两侧的电极是单个电极,谐振器可以是单端口谐振器,或者如果一侧的电极是单个电极,另一侧的电极是双极电极,则它可以是双端口谐振器 。 超晶格晶体谐振器可以用作超晶格晶体滤波器,其形式为由双端口超晶格晶体滤波器形成的单片超晶格晶体滤波器,或以组合超晶格晶体滤波器的形式,其中多个单端口 超晶格晶体谐振器以各种电路配置互连,具有或不具有其它电子部件,例如电容器,电感器和电阻器。
