The plasma generation apparatus includes a chamber including a dielectric window and a toroidal discharge space, a magnetic core disposed to surround a portion of the chamber, an induction coil disposed to wind the magnetic core, and a waveguide radiating a microwave through the dielectric window. Alternating current flowing in the induction coil forms a magnetic flux at the magnetic core, and the magnetic flux generates inductively-coupled plasma. A microwave propagating along the waveguide generates microwave plasma inside the chamber. | 05-15-2014 |
20140218076 | Synchronization of RF Pulsing With RF Metrology, Processing, and Control - A radio frequency (RF) system is disclosed. The RF system includes an RF sensor, an analog to digital converter (ADC) module, a processing module, and a synchronization module. The RF sensor measures a parameter of an RF output and generates an RF signal based on the parameter. The ADC module converts samples of the RF signal into digital values. The processing module generates processed values based on the digital values. The synchronization module outputs one of the processed values in response to a transition in the RF output. | 08-07-2014 |

20110175954 | METHOD OF DRIVING A DISPLAY PANEL, DRIVING UNIT FOR PERFORMING THE METHOD, AND DISPLAY APPARATUS HAVING THE DRIVING UNIT - A driving unit of a display panel includes a control part, a gate driving part, a grayscale compensating part, and a data driving part. The control part provides a control signal and a grayscale signal. The gate driving part provides a gate signal to the display panel. The display panel is divided into a plurality of blocks according to a distance from a light source to each of the blocks. The grayscale compensating part outputs a compensating signal of an n-th frame using look-up tables, and the look-up tables respectively correspond to the blocks of the display panel. The data driving part converts the compensating signal of the n-th frame into a grayscale voltage and provides the grayscale voltage to the display panel. Accordingly, the driving unit of the display panel may improve a response speed of liquid crystals and display quality. | 07-21-2011 |
20120249518 | DISPLAY DEVICE - A display device includes a plurality of pixels arranged in matrix, a plurality of gate lines, a plurality of data lines, and a gate driver connected to the plurality of gate lines. The gate driver receives a first scan start signal, a second scan start signal and clock signals and outputs a gate-on voltage to each of the plurality of gate lines. The gate driver outputs the gate-on voltage to the plurality of gate lines such that the gate-on voltages do not overlap with each other when the gate driver receives the first scan start signal. The gate driver outputs the gate-on voltage to at least two of the gate lines at substantially the same time when the gate driver receives the second scan start signal. | 10-04-2012 |
