  • Patent number: 9720268
    Abstract: An edge narrowing method for a display panel is disclosed. The method includes the steps of providing the display panel, a grinding apparatus and a polishing apparatus; tilting the display panel so that the first substrate and a grinding member of the grinding apparatus have a first grinding angle therebetween; grinding the first substrate and the light-shielding area with the grinding apparatus while the display panel is tilted at the first grinding angle, thereby forming a first grinding end surface; stopping grinding of the first substrate and the light-shielding area when the width of the light-shielding area is between 0.35 and 1 mm; and polishing the first grinding end surface with the polishing apparatus to form a first end surface.

  • Patent number: 8948474
    Abstract: A quantification method and an imaging method are disclosed, capable of quantifying the margin feature, the cysts feature, the calcifications feature, the echoic feature and the heterogenesis feature of a tumor, and capable of imaging the margin feature, the cysts feature, the calcifications feature and the heterogenesis feature of a tumor. The quantification method and the imaging method calculate the moving variance of the gray scale of each of the pixel points based on the gradient value of the gray scale of these pixel points. Then, depending on the purpose of the quantification method or the imaging method, the maximum value, the minimum value, the mean value, and the standard deviation of the moving variance of the gray scale of these pixel points are calculated, respectively. At final, with the definition of the threshold value and the imaging rule, the above features of the tumor are quantified or imaged.

  • Publication number: 20090225049
    Abstract: The present invention discloses a sliding method for touch control comprising the following steps. First, an input module is used to touch a first position and a second position on a touch display interface, and the touch display interface generates a time signal while being touched. The time signal is compared with a preset time signal to determine stopping actuation or sliding. In case of a sliding motion, first direction actuation is performed when a first direction function is larger than a second direction function, whereas second direction actuation is performed. Next, a velocity function signal is derived according to the distance and the time signal, and then compared with the first and second preset velocity functions to determine first, second or third velocity actuation.
