  • Patent number: 8354986
    Abstract: A displaying method for trans-flective type display device is provided. The pixel array of the display device has a selected pixel unit formed by three sub-pixels selected from three basic-color sub-pixels and one enhancement sub-pixel, wherein there is a reflective area within the enhancement sub-pixel. The displaying method includes the following steps. Firstly, an original image having an image data is provided to the display device. Next, when the backlight is turned off, the resolution of the original image is scaled down for obtaining an adjusted image data. Then, another pixel unit consisting of the three basic-color sub-pixels and the enhancement sub-pixel is re-selected, and the driving value of the enhancement sub-pixel is calculated according to the adjusted image data for driving the enhancement sub-pixel.

  • Publication number: 20110151927
    Abstract: The present invention provides a serial transmission interface of a portable electronic device. The portable electronic device includes a control module, a display module and an image sensing module. The serial transmission interface includes a first line group coupled to between the control module and the image sensing module, and includes a second line group coupled to between the control module, the display module and the image sensing module; wherein when the control module sets the image sensing module to a master mode through the first line group, the image sensing module directly transmits captured image data to the display module through the second line group. The present invention further provides a portable electronic device and a data transmission method of the serial transmission interface of a portable electronic device.

  • Publication number: 20100113093
    Abstract: A serial transmission interface between an image sensor and a baseband circuit includes a transmission end and a reception end. The transmission end is set in the image sensor, and is utilized for transmitting image data sensed by the image sensor. The reception end is set in the baseband circuit, and is utilized for receiving the image data transmitted from the transmission end. The transmission end is one of a master control end and a slave control end, and the reception end is correspondingly the other.

  • Patent number: 7215356
    Abstract: A 3D stereo display method and a device thereof. Two sets of shutters are disposed in a display. The shutters are complimentarily interlaced with each other. The opening/closing of the two sets of shutters are controlled by time interval concept. When the display frequency is odd frequency, one set of shutters is activated. When the display frequency is even frequency, the other set of shutters is activated. The two sets of shutters are continuously opened and closed according to the variation of the frequency so that in odd and even frequencies, the left and right eyes can respectively see independent images formed of different subpixels. Therefore, a 3D display effect is presented to bare eyes without reducing resolution.

  • Publication number: 20070086090
    Abstract: An image display device includes a display panel and a parallax optic. The display panel is provided with a stripe sub-pixel arrangement in which sub-pixels arranged in a first direction have identical colors, and sub-pixels arranged in a second direction have distinct colors. The pixel density in the first direction is twice the pixel density in the second direction of the stripe sub-pixel arrangement. The parallax optic has view-separation elements arranged in the first direction into multiple rows. Each view-separation element is positioned corresponding to two adjacent sub-pixels, and the view-separation elements in one row are staggered relative to the view-separation elements in immediately adjacent rows.

  • Patent number: 6386119
    Abstract: A foldable leg for furniture includes a tubular leg and a pivot assembly attached to a top of the tubular leg. The pivot assembly includes a front plate and two wing plates respectively perpendicularly extending from two opposite sides of the front plate and facing each other. Each of the wing plates has a curved top edge and an elongated slot longitudinally defined in each of the wing plates. A bracket is pivotally connected to the pivot assembly and includes two side plates parallel to each other, and each has a through hole defined in a lower portion of the side plate. A locking plate connects the two side plates and the locking plate is selectively locked by the pivot assembly. A spring has two ends respectively secured around the pivot pin and at a free end of the tongue of the pivot assembly.

  • Patent number: 6286729
    Abstract: A feeding device for a caulking gun includes a frame, a trigger, a plunger shaft, a drive grip, a brake grip, two springs and a pressure release rod. A first recess and a second recess are defined in the frame. The plunger shaft extends through the frame and penetrates the drive grip, in the first recess, and the brake grip, in the second recess. The pressure release rod is slidably mounted between the drive grip and the brake grip. When the drive grip is moved back, due to a spring force, and presses the pressure release rod, the brake grip is pressed, to release the engagement with the plunger shaft, which releases the pressure on the caulking compound in the tube. Consequently the caulking compound does not flow out of the tube unless the trigger is squeezed and caulking compound is saved.
