  • Publication number: 20130241865
    Abstract: The present invention discloses a touch display device and a touch measuring method for determining touch positions thereof. The touch display device includes a touch sensing module, a substrate, a pressure sensing device disposed between the touch sensing module and the substrate, and an integrating device. The method includes a first position measuring step, a step of sensing an initial pressure, an initial pressure sensing step, a second position measuring step, a real-time pressure sensing step and a data integrating step. The first and second position measuring steps are to measure X-axis and Y-axis coordination values. The real-time pressure sensing step is to sense pressure change between the first and second positions. The data integrating step is to integrate data of the first and second positions and initial and real-time pressure values. The sensed pressure represents a Z-axis position corresponding to X-axis and Y-axis.

  • Publication number: 20120045171
    Abstract: A light guide bar and an optical touch panel utilizing the light guide bar are provided. The light guide bar is applied to an optical touch panel with a sensing area. The light guide bar includes a bar body and a plurality of prisms. The bar body has a first receiving end, a light-exiting surface, and a structure surface. The light-exiting surface is opposite to the structure surface and faces the sensing area while the first receiving end is connected between an end of the light-exiting surface and an end of the structure surface. The prisms are formed on the structure surface. Each prism includes a first surface and a second surface respectively having a first angle and a second angle with respect to the structure surface, wherein the second surface is closer to the first receiving end than the first surface, and the second angle is larger than or equal to the first angle.

  • Publication number: 20110193752
    Abstract: A handheld device is disclosed, which includes an appearance part, a system ground plane and a detachable element. The detachable element includes a carrier and a planar antenna. The system ground plane is disposed in the appearance part and has a feed point. The planar antenna is disposed on the carrier and has a connection point. The carrier is detachably connected to the appearance part. When the carrier is connected to the appearance part, the above-mentioned connection point is electrically connected to the feed point. In this way, the radiation performance of the antenna can be improved and the frequency band of the antenna of the handheld device can be changed by replacing the detachable element.

  • Publication number: 20100315571
    Abstract: A liquid crystal display (LCD) device is connected with a printed circuit board (PCB) mounted to an electronic device. The LCD device includes a display module having a bare copper area, a holding frame for receiving the display module, and a shielding casing coupled to an end of the holding frame after the display module being assembled to the holding frame. The shielding casing has a bottom plate disposed between the display module and the PCB. The bottom plate has a portion contacting the bare copper area of the display module, and a contacting strip biased from the bottom plate and abutting against the PCB, for preventing the ESD from impacting the display module.

  • Patent number: 7339958
    Abstract: A system for performing signal synchronization of data streams having frames associated with source time reference. A system clock generates a local time reference. A decoder processes the data stream. A system controller determines a difference between the source time reference and the local time reference, compares the difference against a first threshold, selects a target frame from the data stream according to content thereof, and directs the decoder to process the target frame or a frame adjacent thereto.

  • Patent number: 6002442
    Abstract: The present invention discloses a system for adaptively reducing flickers in converting non-interlaced video signals to interlaced video signals. To preserve the original image quality in the non-interlaced video signals, the disclosed system examines the pixel values in at least two adjacent lines to decide if a reduction process should be turned on. If there is a need, the reduction process further examines the difference in the pixels from the adjacent lines to determine how to adjust a corresponding output to eliminate flickers in the resultant converted video signals. The adjusting means is based on an adjusting factor or the calculated difference between pixels which is further used in a function to eventually produce a converted interlaced signal with minimum visual errors.
