AI Technical Summary

Benefits of technology

The present inventors have developed a technology for improving LCD displays without affecting their performance or producing shiny images due to changes caused during the process called “charged particle interference” phenomenon. This results because pixels cannot maintain consistently at the desired level even if they were initially set up correctly beforehand. By adjustting certain parameters such as the number of times data was written onto specific lines within one frame period, this technology allows for more precise control over how much light could enter through different parts of the backlight unit's lens system compared to traditional methods like turning off all lights after every scan. Overall, these technical improvements improve the overall effectiveness and efficiency of LC displays while reducing manufacturing costs.

Problems solved by technology

This patented describes various technical features related to improving the performance of liquid cathode ray tube devices used in electronic equipment such as televisions or monitors. These improvements include reducing impedances caused by the dielectrics within the device itself, prevention of cross talk signals during operation, reduction of power consumption, better design techniques for addressing issues like excessively charged voltages, improved efficiency of displaying images, reduced dark spots associated with brightness variations, etc., and development of a more efficient way to achieve higher definition and faster response times without generating unwanted side effects.

Abstract

The invention provides a LCD of a double-film transistor pixel structure, containing first and second scanning lines, first and second signal lines, and pixel. The pixel contains pixel electrodes, and first and second transistors. The gates and sources of the first and second transistors are linked with the first and second scanning lines and the first and second signal lines, respectively, the drains of the two transistors are connected to the pixel electrodes. The first transistor channel's length-width ratio is less than the second one's.
