There are good and bad indicators-response time, usually not for LCD monitors ^ I ^ \ You: Normally white mode (Normally white , NW) and normally black mode (1 leg / ^ ^), the bright light type means that the display sulfur is not applied and the light is transparent, and the daytime, normally black mode is the display panel without voltage At present, a part of ϋ is the black daylight surface. Taking the normally bright mode as an example, the response time can be divided into two:? 90 〇 / 〇, under-reduced to 10 /. Twist time required for the daylight LCD, referred to as "丁 r"; and ⑺ fall response time, that is, without applying voltage, the brightness of the liquid crystal cell from 1〇 The response time required by the LCD is referred to as “Tf.” Once the display speed exceeds% per second, if the side frame is ㈣, the human eye will regard the fast-changing surface as a continuous daytime surface, but now home entertainment, For example, when playing high-quality WD movies, and fast mining images during games, the display speed is often on the side of the screen every second. In other words, the frame interval time of each frame is 1 / 6〇 = 1667ms. The display ^ response time ^ The interval between the frames will cause afterimages or tabs ^ appearing on the display screen, which will seriously affect the quality of the viewing image. How to improve the response speed must be viewed from the factors that affect the response time. The following equations are the rise response time and the fall response time, respectively. Calculate the equation: Τ = —-v T _ rxd2 r M 2 2) where τi: the viscosity coefficient of the liquid crystal material; d · the liquid crystal cell gap, V: the liquid crystal cell Driving voltage; Δε: the dielectric constant of the liquid crystal material. From the above formula, we know that there are four ways to reduce the response time of the liquid crystal display: reduce the number of LCDs, reduce the gap between the liquid crystal cells, increase the driving voltage, and increase the dielectric coefficient. ver drive) technology, which can be driven by liquid crystals.

It can be set to ^ value and ^ integer. A is based on the synchronization control signal generated by the liquid crystal display less than or equal to the display panel ^ tiger ^ most ^^ is an integer equal to 2. The time intervals of the intervals are / = good, that is, c. In the time of the synchronous control signal, :: a gate line, and then in the next synchronous control—Dream ^, Di Er area ..., and M area The second sequence of the second zone ... and the second sequence of the M zone opens the first zone of the first zone, the first frame of the accelerated acceleration of Doujia, among which the gate line of the You group gives an electric charge 4 is the job information given by Zheng Wei.

Fan Wei | The scope of patent protection of the present invention must therefore be as follows: The present invention has the following advantages: L If the technology is used to shorten the brightness of the liquid crystal display, it can improve the gray scale of the image. The anti-space is divided into a plurality of scanning areas, and using the "0" technique, at the same time, a pre-voltage value or a data voltage is applied to the mother scanning areas to improve the panel response speed 17 200534227 and quickly achieve the desired brightness. Fei ", the inconspicuous panel, is of great industrial use value. The “providing-recording speed” of obtaining image resources is of great industrial value. In summary, the present invention can indeed achieve the expected purpose of improving the grayscale response speed of the desired brightness.
