摘要:
A display includes a display panel, a driver, a memory and a scaler. The driver is used for driving the display panel. The memory is used for storing multiple sets of preset modes. The scaler is electrically connected to the memory and the driver. When the scaler receives an image signal corresponding to at least two different applications, the scaler provides the different preset modes of the applications to non-overlapped display zones, which the applications located in, of a display frame, such that the driver can simultaneously drives at least two of the different preset modes on the display panel.

A positioning method for obtaining position where a light pen is in contact with a display device at a to-be-positioned spot is provided. The display device includes display areas, corresponding with positioning coding patterns of a built-in positioning frame. The positioning method includes the following steps. Firstly, a positive positioning frame and a negative positioning frame are obtained according to the built-in positioning frame. Next, the positive and the negative positioning frames are respectively added on first original video frames to respectively generate first frame displayed in first frame time and second frame displayed in second frame time. Then the light pen obtains first selected image and second selected image from the first and the second frames respectively. After that, a to-be-positioned pattern is obtained by subtracting the second selected image from the first selected image and a coordinate position of the to-be-positioned spot is obtained.

A method for controlling the display circuit and the backlight source of a display device is utilized to improve the color display performance at the low grey scale region. The method includes dividing a plurality of display data into first original display data and second original display data according to a threshold value; the display circuit outputting the first original display data at a first frame duration; the backlight source outputting a first brightness at the first frame duration; the display circuit adjusting the second original display data according to a first parameter for generating second adjusted display data; the display circuit outputting the second adjusted display data at a second frame duration; lowering the first brightness according to the first parameter for generating a second brightness; and the backlight source outputting the second brightness at the second frame duration.

A signal transfer system. A first device operates with a first voltage and outputs a first signal and a second signal. A protection circuit receives the first and second signals and outputs the first and second signals when the first voltage is greater than or equal to a predetermined voltage, and provides a third signal and a fourth signal when the first voltage is smaller than the predetermined voltage. A delay circuit delays the second and fourth signals to generate a first delay signal and a second delay signal, respectively. A second device operates with the first signal and the first delay signal when the first voltage is greater than or equal to the predetermined voltage, and operates with the third signal and the second delay signal when the first voltage is smaller than the predetermined voltage.

A vertical co-axial multi-tubular diving snorkel which is characterized by the following structural design: an inner tube is disposed inside an outer tube of snorkel, these two tubes are co-axial but their calibers obviously differ from each other so as to form two separate channels; a middle thimble is provided inside the top of outer tube, a plurality of intake valve ports are provided to the top of said middle thimble, an annular flat one-way check diaphragm (referred to as the inhaling diaphragm hereinafter to only let the foreign air enter into the snorkel) is provided to the top surface of said intake valve ports; a flat one-way check diaphragm (referred to as the exhaust diaphragm hereinafter to only let the air in the snorkel be exhausted out of the snorkel), an annular body as a housing is provided to the top of snorkel and with a plurality of spaced intake holes and exhaust holes nearby the inhaling and exhaust diaphragms, an annular flat water check diaphragm (referred to as the water check diaphragm hereinafter) and a sleeve type float (referred to as the float hereinafter) are disposed in sequence below the foregoing intake valve ports on the top edge on the inner periphere of intake holes, and normally the water check diaphragm is on the bottom edge on the inner periphere of said intake holes; and based on such a structure, when the diver uses the snorkel of the present invention for breathing, he or she can avoid inhaling the waste carbon dioxide exhaled by himself or herself because there are different channels for separate intake and exhaust, and during use, when the float contacts the water, the float will be subject to the floating force of water and immediately rise up to push the water check diaphragm to close the intake valve ports so as to prevent the water from flowing into the snorkel.
