  • Patent number: 11295657
    Abstract: The present disclosure discloses a method and system for switched display of a grayscale of a multi-line scan light-emitting diode (LED), and relates to the field of LED display technology. In view of the problems in the prior art that a multi-line scan constant-current source chip has an insufficient refresh rate, a low grayscale level, and a poor low-grayscale effect, the present disclosure provides a method during the display of relatively high grayscales, a display cycle is scrambled. During the display of relatively low grayscales, the grayscales are combined. In the present disclosure, a relatively high refresh rate and a grayscale level can still be ensured in a case of a relatively large quantity of line scans. In addition, in the case of low-grayscale display, the problems such as low-grayscale speckles, slightly dark low-grayscale, and relatively poor low-grayscale linearity are resolved, thereby improving a picture display effect.

  • Patent number: 11282870
    Abstract: To make the dimension of an electrostatic protection circuit small with the same maintained high in sensitivity. The electrostatic protection circuit is of the configuration that a first diode and a second diode are connected in series, wherein a semiconductor layer owned by each diode is configured to be sandwiched between a gate electrode and a conductive light shielding film. The light shielding film is formed to overlap with the semiconductor layer and has a wider area than the semiconductor layer. This results in having a gate covering the semiconductor layer from an upper side and a back gate covering the semiconductor layer from a lower side, so that the sensitivity can be maintained high irrespective of decreasing the electrostatic protection circuit in dimension.

  • Patent number: 11256345
    Abstract: A hand operated computer input device comprising a main body with a flat support surface for the entire palm heel is provided. The new support surface provided is not for the palm, metacarpals, proximal and intermediate finger segments, or wrist. Only a user's palm heel and finger tips touch the input device. The entire palm heel wholly supports the weight of a users hand and arm. There is no pressure on the median nerve at the wrist or in the hand. There is no angle at the wrist while the hand maintains a generally neutral position. The height between the top of the palm heel support surface and the top surface of the buttons, wheels, etc. places the hand in a generally neutral, relaxed cupped position. The present invention seeks to prevent repetitive strain injury (RSI) and Carpal Tunnel Syndrome while using a horizontal or vertical hand operated computer input device.
