    摘要: A manufacturing method for a photoelectric package structure having a control chip is proposed. The photoelectric package structure concentrates light emitted therefrom, prevents external light interference and can be applied for advertising signs and backlight modules. Using the present invention increases the defect-free ratio and production quality. Applying the present invention for packaging light-emitting diode (LED) or optical sensor chips allows the necessary light-emitting requirements of electronic chips to be easily met. The package structure of the present invention is superior to conventional ones and the installation of the control chip doesn't reduce the light-emitting intensity. The major innovation of the present invention is disposing a photoelectric chip (or multiple photoelectric chips) on a control chip and then installing the control chip upon a substrate. Thus, installation-of the components is more convenient. Furthermore, an external frame or optical gratings can also be included to prevent external light interference.

    摘要: A Junction Field Effect Transistor (JFET) can be fabricated with a well region that include a channel region having an average dopant concentration substantially less the average doping concentration of the remaining portions of the well region. The lower average doping concentration of channel region compared to the remaining portions of the well region reduces the pinch-off voltage of the JFET.

    摘要: The LEDs of a display panel are arranged in a matrix array and oriented at an angle with the directions of columns or rows. Such an orientation causes the diffused light incident on neighboring LEDs of activated LEDs to create a shaded area with the same aspect ratio of the activated pattern and to yield a virtual stereoscope illusion.

    摘要: A wide image scanner which can scan the image of a large scale original using only a regular image sensor is provided. The invention includes a sliding shaft, an image reading device, a number of paper width sensors, a paper edge sensor, and a control module. Whenever the paper edge sensor detects the presence of an end edge of the original, it will send a vertical control signal to the control module to control the rotation direction of the rollers. On the other hand, the paper width sensors detect the width of the original and send the horizontal control signals to the control module. From the horizontal control signals, the control module can determine the number of horizontal displacement positions and control the horizontal displacement each time for the image reading device after the paper edge sensor detects the end edge of the original. The procedure continues until the image reading device has been moved to the final displacement position predetermined by the horizontal control signal. Consequently, the entire image of the origin can automatically be read portion by portion without manual operation.

    摘要: A cost effective and easily assemblable image scanning device with a relatively stable and satisfactory scanning effect is disclosed. The present image scanning device is used in an image scanner having a light source and a focusing reflector device. The image scanner device includes a brightness reflection device for generating a brightness reflection signal in response to a light signal from the light source; an image sense device for respectively generating an image sense signal and a reference brightness signal in response to an object reflection signal from the object to be scanned and the brightness reflection signal; and a brightness-controlling device electrically connected to the image sense device for compensating the image sense signal in response to the reference brightness signal.
