Nowadays, RT and MPRT become a very important factor to judge image quality. We have developed fastest response time and motion picture response time TFT LCD of the world for image quality request. Our panel can reach RT 2ms and gray to gray RT avg. below 2ms. We also combine the fastest cell and advanced over-drive system to make MPRT be 4ms.

A prototype 120 Hz 110-inch ultra-high-definition a-Si liquid crystal display (LCD) panel was successfully developed using the BOE exclusive advanced superdimensional switching technology. This LCD has a panel consisting of 3840 × 2160 pixels, four times the number of pixels in the conventional full-high-definition LCD. For the brightness and contrast ratio, 1000 nits and 1200:1 have been achieved, respectively. Additionally, the liquid crystal charging time has been extended through quad area driving and 2G2D line structures. Furthermore, the local dimming and mirror-scanning techniques are applied to realize excellent image display. Finally, the system utilizes 3D shutter glasses, allowing the viewer to achieve the highest sense of realness and immersion.

A magnetically insulated transmission line (MITL) is used to transmit high power electric pulses in large pulse power systems. However, current loss is unavoidable, especially when the current density is up to 1 MA/cm. In the paper, the current loss of an MITL made of stainless steel, which is usually used in large pulse power generators, is experimentally studied, and possible mechanisms to explain the current loss of the MITL are analyzed and discussed. From the experimental results, the relationship between loss current density and input current density follows approximately a power law. The loss is also related to the configuration of the MITL.

Events consist of objects in motion. When objects move, their opaque surfaces reflect light and produce both static image structure and dynamic optic flow. The static and dynamic optical information co-specify events. Patients with age-related macular degeneration (AMD) and amblyopia cannot identify static objects because of weakened image structure. However, optic flow is detectable despite blurry vision because visual motion measurement uses low spatial frequencies. When motion ceases, image structure persists and might preserve properties specified by optic flow. We tested whether optic flow and image structure interact to allow event perception with poor static vision. AMD (Experiment 1), amblyopic (Experiments 2 and 3), and normally sighted observers identified common events from either blurry (Experiments 1 and 2) or clear images (Experiment 3), when either single image frames were presented, a sequence of frames was presented with motion masks, or a sequence of frames was presented with detectable motion. Results showed that with static images, but no motion, events were not perceived well by participants other than controls in Experiment 3. However, with detectable motion, events were perceived. Immediately following this and again after five days, participants were able to identify events from the original static images. So, when image structure information is weak, optic flow compensates for it and enables event perception. Furthermore, weakened static image structure information nevertheless preserves information that was once available in optic flow. The combination is powerful and allows events to be perceived accurately and stably despite blurry vision.

The post-hole convolutes (PHCs) are used in pulsed high-power generators to add the output currents of the magnetically insulated transmission lines (MITLs) and deliver the combined current to a single MITL. Then the single MITL delivers the combined current to the load. Magnetic insulation of electron flow is lost near the post-hole convolute (PHC) in the high-power generator. Although cathode plasma and anode ions are widely considered as the factors of the magnetic insulation collapse, there are some other factors that are needed to study. In this paper, the cathode negative ions are considered in the PIC simulation of a single-hole PHC. In this work, we examine the evolution and dynamics of the negative ions in the PHC. The simulation results demonstrate that there are no current losses while the cathode emits only electrons, little current losses (10 kA out of a total current of 900 kA) while the cathode emits plasma including electrons and ions, and obvious current losses (20 kA out of a total current of 900 kA) while the cathode emits plasma including the electrons, ions and negative ions. The results also indicate that the velocity of the negative ions is about 10 cm/μs, larger than that of the cathode plasma including the electrons and the ions. All results suggest that the cathode negative ions can play an important role in the magnetic insulation collapse, and should be considered carefully in experiment.
