The invention discloses a synchronous and asynchronous bi-gate thin film transistor (TFT)-organic light emitting diode (OLED) pixel drive circuit and a drive method thereof. The pixel drive circuit comprises a first transistor, a second transistor, a storage capacitor and a light emitting diode, wherein, the first transistor is a synchronous bi-gate TFT and the second transistor is an asynchronous bi-gate TFT. A synchronous bi-gate structure and an asynchronous bi-gate structure are introduced in on the basis of the traditional 2T1C circuit and a precharging voltage and a feedback line are added to the pixel drive circuit. Thus, the maintaining effect to data voltage at a non-gating stage of the storage capacitor is effectively improved. In addition, the threshold voltage compensation of the driving transistors is effectively realized. Thus, the uniformity and the stability of the luminance of displays are ensured. Compared with most pixel drive circuits which are adopted to realize data maintaining and threshold compensation, the transistors, the capacitors and the control lines are saved and the circuit structure is greatly simplified. Thus, the opening ratio and the resolution ratio are increased and the cost is reduced.

Throttles electronic devices based on compliance with rules for electronic communications such as emails, texts, or postings on social media sites. Rules may for example prohibit certain topics, language, or behaviors such as online bullying. If system detects a violation of the electronic communications rules, it may block access or reduce performance on one or more electronic devices as a consequence. In some cases, devices or selected apps or services may continue to function, but at a reduced level. Conversely the system may provide rewards for conforming with the rules. Throttling of devices may also depend on other factors, such as homework completion, test results, grades, and environmental conditions. Machine learning techniques may be applied to determine when electronic communications may violate the rules. For example, probabilistic topic models may be applied to determine the topics of electronic communications, and to assess whether these topics violate the rules.

The invention relates to a naked eye 3D (three-dimensional) television wall, comprising a full-color LED (light-emitting diode) array and a slit grating (or a lenticular grating), wherein the grating is arranged in front of an LED display array and parallel to an array plane; and the grating and the row direction of LEDs form an angle of inclination.
