Description of the Invention: [Technical Field] The present invention relates to a method for state transition of a display, and more particularly to an optical self-compensating birefringence type (〇pticaUy compensated birefringence) 'OCB) Liquid crystal display for fast transition state transitions. ~ [Prior Art] The liquid crystal display is divided into many types depending on the type of liquid crystal used, the driving method, and the position of the light source. Among them, the optical self-compensating Birefringence (OCB) liquid crystal display has a fast response speed, and can provide a smoother performance of the computer when playing a continuous change such as a moving movie or a movie, so that Ideal for high-end LCD applications. However, an optical self-compensating birefringence type liquid crystal display (hereinafter referred to as an OCB liquid crystal display) must allow optical self-compensating birefringent liquid crystal molecules (hereinafter referred to as liquid crystal molecules) to be converted to a Bend state via a Splay state. In order to enter the standby state, and provide a quick response performance. FIG. 1A is a schematic view showing a 〇cb liquid crystal molecule in a stretched state. The figure shows a schematic diagram of the OCB liquid crystal molecules in a curved state. Referring to FIG. 1A and FIG. 1B together, the conventional OCB liquid crystal display 100 has 〇cB liquid crystal molecules 130' disposed on a color filter substrate 110 (c〇1〇r fllter substrate) and a thin film electric solar array substrate 120 ( Between thin film transistor array substrate). The color filter substrate 11 () has a first electrode 112, and the thin film transistor array substrate 120 5
1305334 16605tw£doc/r 具有多數第二電極122 (在此僅繪示一個）。如圖ία所繪 示，當未施加電壓到第一電極112與第二電極122上時， OCB液晶分子130因未受到外加之電場作用，而以展曲態 方式排列。然而，如圖1Β所繪示，當〇CB液晶顯示器1〇〇 欲進入待機狀態時，必須對第一電極112與第二電極 分別施加電壓，而造成一垂直彩色濾光基板11〇以及薄膜 電晶體陣列基板120的轉態電場e，因受到垂直轉態電場 E的影響，OCB液晶分子130將漸漸轉變為彎曲態。 但是，習知的OCB液晶顯示器1〇〇若要正常驅動， 需要數分鐘的時間來進行這個轉態過程，即在進入待機狀 態剷，需要長時間暖機(warm up)。所以，這對於〇cb、夜 晶顯示器100所應具備之隨開即用的特性十分不利。= 此’要讓OCB液晶顯示器100更容易為消費者所接受， 快速轉態(Fast transition)是必須的。 、 ^習知技術中，使0CB液晶分子從展曲態快速轉離糾 ¥曲態的方法大致可分成三類設計。第—種方法是:ζ 濾、光基板110與薄膜電晶體陣列基板m之間施加I 壓，如圖1B所繪示。當0CB液晶分子13〇受到雷=二 造成之高轉態電場E的作用時，qCb液晶分子13二 地從展曲態轉換到彎曲，態。但是，此種施加高電壓广 其可對應使㈣源_動日日日片（WeeIC)較少万 這種方式也比較耗電。 利用 而第二種方法是添加聚合物到 0CB液晶分子的預傾角（pre_tilt OCB液晶層中而增加 Angle)。此方法是利 1305334 16605twf.d〇c/r ^添加會對％外光反應的聚合物，以穩定⑻B液晶分子 。此預傾角可用來控制液晶分子的傾倒方向，也 ，，液晶分子的長軸與電場的方向具有—傾斜角度， 、而使彈性力能夠快速在〇CB液晶分子之間傳遞。但是， 添加^合物的製程較為複雜，且量產可行性不高。1305334 16605 tw £doc/r has a plurality of second electrodes 122 (only one is shown here). As shown in Fig. ία, when no voltage is applied to the first electrode 112 and the second electrode 122, the OCB liquid crystal molecules 130 are arranged in a stretched state because they are not subjected to an applied electric field. However, as shown in FIG. 1A, when the 〇CB liquid crystal display 1 is intended to enter a standby state, a voltage must be applied to the first electrode 112 and the second electrode, respectively, to cause a vertical color filter substrate 11 and a thin film. The transitional electric field e of the crystal array substrate 120 is gradually affected by the vertical transition electric field E, and the OCB liquid crystal molecules 130 are gradually transformed into a curved state. However, if the conventional OCB liquid crystal display 1 is to be driven normally, it takes several minutes to perform this transition process, that is, when entering the standby state, it takes a long time to warm up. Therefore, this is very disadvantageous for the on-off characteristics that the 〇cb and the night crystal display 100 should have. = This makes the OCB LCD 100 more acceptable to consumers, and a fast transition is a must. In the conventional technique, the method of rapidly shifting the 0CB liquid crystal molecules from the curved state to the corrected state can be roughly divided into three types of designs. The first method is: ζ filtering, applying an I pressure between the optical substrate 110 and the thin film transistor array substrate m, as shown in Fig. 1B. When the 0CB liquid crystal molecule 13 is subjected to the high-transition electric field E caused by Ray=2, the qCb liquid crystal molecule 13 is switched from the expanded state to the curved state. However, such a high voltage application can be used to make (4) source_days (WeeIC) less than 10,000. This method is also relatively power-hungry. The second method is to add a polymer to the pretilt angle of the 0CB liquid crystal molecules (in the pre_tilt OCB liquid crystal layer to increase the Angle). This method is a 1305334 16605 twf.d〇c/r ^ added polymer that reacts with % external light to stabilize the (8) B liquid crystal molecules. The pretilt angle can be used to control the tilting direction of the liquid crystal molecules. Also, the long axis of the liquid crystal molecules has an oblique angle with the direction of the electric field, so that the elastic force can be rapidly transferred between the 〇CB liquid crystal molecules. However, the process of adding a compound is complicated and the feasibility of mass production is not high.

Please refer to FIG. 2 and the circuit of the liquid crystal display panel of FIG. 2 includes a gamma circuit component 2, a liquid crystal display device 200, for example, a voltage vdrive to the second electrode 214 in FIG. 7), when the driving connection is applied to The plurality of galvanic circuit elements 230 of the second electrode 2M are short-circuited to each of the second electrodes 214, so that the electric field E of the wheel shown in FIG. 2 is the same, and the voltage VdHVe is the same. Therefore, the side 6 of the driving voltage has an optical self-compensating refraction applied to the second electrode 214; the direction of the voltage across. That is to say, the drive of the castle _ is converted from the low frequency and/or the low ground to the curved state. Turning, the effect of ^% £' and the advantage of the fan: As described above, the driving method of the liquid crystal display of the present invention has the following low voltage/low voltage driving type liquid crystal layer capable of functioning, so that the optical compensation double The warm-up time of the refracting liquid crystal display is converted into a f-curve state, and then shortened, and the power can be turned on, and the power consumption of the liquid crystal display is reduced, thereby achieving the payment of 4 Therefore, it is difficult to increase the difficulty of taking 13 1305334 16605twf.doc/r to drive the wafer, and it is also feasible for mass production. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
