  • Patent number: 11996025
    Abstract: A GOA circuit and a display panel are proposed. An inverting control module controls the voltage level of the first node to be opposite to the voltage level of the second node under the control of an (n+1)th-stage clock signal, so that a DC path between a constant high voltage terminal and a first constant low voltage terminal is not formed. When a first node is at the low voltage level, the voltage applied on the second node transitions from the low voltage level to high voltage level. Accordingly, the second node is constantly at the high voltage level at the pull-down maintenance stage in the GOA circuit, and the nth-stage gate-driven signal terminal is still at the low voltage level. In this way, the GOA circuit will not become ineffective.

  • Patent number: 11922901
    Abstract: A system and method for control of perceived brightness level in a display device based on the brightness of individual content items to provide a consistent viewing experience. This is a method of visual content-based brightness control. Adjusting the perceived display of individual visual content items does not rely on the adjustment of a display device's settings or controls, such as a general setting to control the brightness of a display screen, but rather evaluates the visual content being presented and adjusts the presentation layers for display of the visual content provided as part of the display screen. In this way, adjusting parameter(s) of one or more of these presentation layers provides control over the brightness level of the displayed content as a function of the brightness of the content.
