  • Publication number: 20200365738
    Abstract: A laser processing apparatus and a stack processing apparatus are provided. The laser processing apparatus can perform steps selectively by switching of optical paths. The steps are a step in which a first surface of a flat-plate structure is irradiated with a laser and a step in which a surface opposite to the first surface of the structure is irradiated with the laser. The laser is a linear laser whose shape on the irradiated surface is a rectangle. By laser irradiation performed while the structure is moved in the horizontal direction, the whole or a desired region of the first surface or the opposite surface of the structure can be processed.

  • Patent number: 10770482
    Abstract: A display device capable of improving image quality with low power consumption is provided. A storage node is provided in each pixel and a first signal can be held in the storage node. A second signal is added to the first signal by capacitive coupling to generate a third signal. A display element operates in response to the third signal. Thus, regardless of the output voltage of a driver that supplies data, a high voltage can be supplied to the display element. Consequently, even a display element that requires a relatively high voltage for operation can operate with low power consumption.
