摘要： A method of driving a pixel element in a matrix of pixel elements includes (1) setting the bias voltage of a first transistor to a value that is substantially close to a threshold voltage of the first transistor by changing a voltage across a first capacitive element with a current passing through the first transistor; (2) setting the bias voltage of the first transistor to a value that is different from the threshold voltage of the first transistor; and (3) causing a change of the bias voltage of the first transistor.

摘要： The present disclosure proposes a force touch structure, a touch display panel and a display apparatus. The force touch structure comprises a base substrate, a light sensing device located on the base substrate, and a phosphorescence-emitting structure positionally corresponding to the light sensing device. The phosphorescence-emitting structure comprises a first electrode, a second electrode, a phosphorescent layer, and a flexible material layer. The first electrode receives a first voltage signal, the second electrode receives a second voltage signal, and the first electrode and the second electrode are used for forming a capacitor with a constant voltage value under the effects of the first voltage signal and the second voltage signal. The light sensing device is used for receiving phosphorescence emitted by the phosphorescent layer and comparing an intensity of the received phosphorescence with a light intensity detected without force touch to determine the magnitude of force touch.

摘要： An integrated drive circuit for multi-segment electroluminescent displays is provided. During a charging phase, the electroluminescent segments are charged by a common charge circuit, and partially discharged using separate discharge circuits associated with individual electroluminescent segments. A controller provides essentially independent control over the respective discharge circuits so, by the end of the charging phase, the EL segments can be charged to correspondingly different final voltages. Then during a discharging phase following the charging phase, the electroluminescent segments are completely discharged, thereby emitting an intensity of light that varies roughly in proportion to the final accumulated voltage. The controller can be pre-programmed with a spatial-temporal light pattern so that, using the disclosed integrated drive circuit, the electroluminescent display can be operated to generate rudimentary animations.

摘要： The invention comprises of the installation of an array of light emitting diodes (LEDs) to the moving parts of any wind turbine. The LEDs are controlled to generate a viewable image when the turbine blades or other parts are rotating. The image is generated by individual control of each LED while the array of LEDs follows the movement of the wind turbine blades, thus sweeping an area where the image appears. Means for controlling the LEDs include variable speed control to generate steady or moving images when the turbine rotates at variable rotational speeds. Electricity generated by the turbine may be used to power the LEDs and controller. LED arrays can be arranged anywhere on the moving parts of the turbine.

摘要： An organic electroluminescent display system comprising at least one organic-light-emitting diode (OLED), a zener diode in series to the organic light-emitting diode, a rectification diode, and a capacitor used as a memory device. During a frame period of the display device, there are address and light emission periods. A reverse bias voltage is applied across the organic light-emitting diode during the address period to prevent metal migration into the organic layers of the OLED. Current mode data programming is used to address the display device. During the light emission period, charge previously stored in selected capacitors during the address period supplies a forward current for the OLEDs. A ramp waveform applied to the row electrode during the light emission period, forces the capacitor to discharge through the OLED and controls the forward current level. This keeps the operation of the OLEDs in their area of maximum performance.
