摘要： The present disclosure provides a circuit for discharging parasitic capacitance in a display panel with common-anode topology having a plurality of light emitters, as well as a circuit for charging parasitic capacitance in a display panel with common-cathode topology. In the common-cathode topology, the circuit includes a three-terminal device having a gate, a source, and a drain, wherein one of the source and the drain is electrically coupled to a common cathode of the light emitters, and a mechanism for controlling the three-terminal device, the mechanism being electrically coupled to the gate. Shortly after a previously selected light emitter is unselected, the mechanism turns on the three-terminal device to form a conductive path between the source and the drain. The mechanism turns off the three-terminal device after a voltage at the common cathode is increased to a predetermined voltage level or after a maximum period of time lapses.

摘要： An improved transmission protocol is used to transmit a signal between two components of an electronic device. The improved transmission protocol is configured to reduce the number of simultaneous channel transitions that occur when multiple signal channels are transmitted in parallel. Reducing the number of simultaneous channel transitions is beneficial because a signal that is subject to skew, distortion, or electromagnetic interference during transmission may have a shorter settling time when fewer channels undergo a transition simultaneously. When the protocol is used to transmit a signal from a controller to an optical pickup unit in an optical data storage system, the reduced settling times allow for a higher data transmission rate.
摘要翻译：改进的传输协议用于在电子设备的两个组件之间传输信号。改进的传输协议被配置为减少当多个信号信道并行发送时发生的同时信道转换的数量。减少同时信道转换的数量是有益的，因为在较少信道同时进行转换时，在发送期间经受偏斜，失真或电磁干扰的信号可能具有较短的建立时间。当协议用于在光学数据存储系统中将信号从控制器发送到光学拾取单元时，减小的建立时间允许更高的数据传输速率。

摘要： A low voltage LED (Light Emitting Diode) driving circuit operates under low supply voltage to provide stable and reliable control of LEDs. The LED driving circuit includes a switching transistor to turn on or off an output current in the LED. The LED driving circuit also includes a control transistor for controlling the level of the output current. The two transistors are coupled via a node that is maintained at a low voltage to increase the voltage across the switching transistor. The increased voltage across the switching transistor allows faster switching and more stable control over different levels of output voltage. The LED driver also includes circuit components for matching the turn-on times and turn-off times for different levels of the output current.
