[Prior Art] ❾ Traditionally, thin film transistor liquid crystal display device (Thin-Film-Transistor Liquid
Crystal Display ’ 簡稱 TFT-LCD)皆需要彩色濾光片(c〇i〇r fllter),來 產生紅(R)、綠(G)、藍(B)三原色。當白光背光源的光穿過彩色濾 光片後,整個光強度被滤掉或吸收掉約70%的光,所以光通過彩 色濾光片的光利用率僅約30%,造成大量的電能損耗。同時,由 於彩色濾光片較低的色彩純度,造成較窄的色域(c〇1〇r gamma domain) ° 〇 目前新興的場序色彩(field sequential c〇1〇r,簡稱FSC)技術由 於不需要彩色遽光片’所以可以消耗非常低的電能。另一方面, 傳統的液晶齡裝置巾的每-晝素必須包含3個次晝素,其分別 需RGB二種顏色的彩色濾光片,但若採用FSC技術,則每一晝素 不必再包含3個次晝素,因此在製作TFT時,晝素便可以輕易地 達到3倍㈣細度’可應用於可攜式峨示產品它高密度畫 素(highPixelPerlnch,簡稱高m)的顯示產品。Crystal Display' (TFT-LCD) requires a color filter (c〇i〇r fllter) to produce three primary colors of red (R), green (G), and blue (B). When the light of the white light backlight passes through the color filter, the entire light intensity is filtered out or absorbs about 70% of the light, so the light utilization rate of the light passing through the color filter is only about 30%, causing a large amount of power loss. . At the same time, due to the lower color purity of the color filter, a narrow color gamut (c〇1〇r gamma domain) is caused. 〇 The current field sequential c〇1〇r (FSC) technology is due to No color enamel is required' so it can consume very low power. On the other hand, the traditional liquid crystal age device towel must contain 3 secondary halogens, which respectively require RGB color filters of two colors, but if FSC technology is used, each element does not need to be included. 3 secondary halogens, so when making TFTs, the halogen can easily reach 3 times (four) fineness' can be applied to the display products of high-density pixels (high-meter pixels).

The denier structure in this embodiment should include a first gate line G1, a first data line D, a second transistor, and a first, C1. Wherein, the electric =: the second electric: TM each - t a second electrode end (such as secret), and the first capacitor C1 includes the first end and the first 0 0 201040926 the gate of the first electric body TFT1 And the first electrode end thereof is connected to the first interpole, and is electrically connected. The first electrode end of the second electro-brass 2 is electrically connected to the second electrode end of the first transistor. The driving circuit of this embodiment may further include a second gate line g2, and the second end of the first capacitor C! of the disk and the second electrode end of the second transistor are electrically connected. The driving circuit of this embodiment may further include a halogen transistor TFTp having a gate - a first electrode terminal (e.g., a source) and a second electrode terminal (e.g., a drain). The first electrode terminal of the halogen crystal is electrically connected to the first data line D1. The idle electrode of the pixel transistor % is electrically connected to the second electrode terminal of the _ transistor TFT and the first electrode terminal of the second transistor TFT2. Therefore, the second electrode terminal of the first transistor TFT1 is electrically connected to the first-bead line D! via the halogen transistor I%. The halogen structure 1〇〇 of the embodiment may further include a storage capacitor cs and a liquid crystal capacitor Clc, each of which has a first end and a second end. The first ends of the storage capacitor & and the liquid crystal capacitor cLC are electrically connected to the second electrode terminal of the halogen transistor TFTp or the 〉-electrode electrode E. The second gate, line & is electrically connected to the gate of the pixel TFT TFT through the first capacitor & In addition, the pixel structure of this embodiment may further include a third gate line & which is electrically connected to the second end of the storage capacitor Q and the gate of the second transistor. In the present embodiment, f three-wire & is adjacent to the second gate line G2, and the second gate line (3⁄4 is adjacent to the first gate line & but in other embodiments may not Please refer to FIG. 4 and FIG. 5 simultaneously, wherein FIG. 5 is a timing diagram of the driving voltage of the embodiment. When the time is T1, the first gate line G1 receives the gate driver (not shown). One of the high voltage Vgh (or enable voltage), the other gate line receives a low voltage vgl (or de-energized voltage) from the driver of 12 201040926, so that the first transistor is printed - turned on 'so the current will Flowing through the second electrode end of the first transistor TFTi, and then flowing to the first end of the ./capacitor C1, charging "generating the pump power Qpu<; when the voltage Vg(1) of the first gate line G! is pulled high Voltage, time, the second electrode line & is electrically connected to the second end of the first capacitor', so it will be affected by the first capacitor q contact effect, and its voltage Vg(2) will eventually change in T1 time. For the low voltage v, add the pump voltage Vpump ' ie vg (2) = Vgl + Vpump (where vpump = Qpump xc D. At the same time, in 〇T1 time, when After the first transistor TFT\ is turned on, the gate terminal of the halogen transistor tftp will pass through the first transistor TFT! and receive the voltage of the first gate line, so that the gate voltage Vg of the transistor TFTP will be pulled up. 'And the crystal transistor tftp will also be turned on (conducted)' and the data signal on the data line D1 will be written to the pixel electrode E. At this time, the data signal written to the pixel electrode E is actually a halogen structure. The data signal of the previous element of 1〇〇. During the T2 time after the end of the T1 time, the second gate line G2 receives a high voltage vgh (enable voltage) from the gate 〇 driver, and the other gate lines Receiving the low voltage Vgl, and at this time, the voltage on the second gate line G2 is pulled up by the pumping voltage Vpump due to the coupling effect of the first capacitor (the coupling effect of the pixel TFT VP through the first capacitor Q) The voltage of the second gate line G2, the halogen TFT TFTP will continue to be in the on state, and the data signal on the data line D! will continue to be written to the pixel electrode E'. The data signal of the electrode E is the actual real data signal of the halogen structure 100. On the one hand, in the T2 time, the first transistor TFT] and the second transistor TFTJW# are in an off state. Specifically, the voltage Vg(2) of the second gate line G2 of the 13th 201040926 is shown. After the first capacitor C1 has been pulled up to Vgi+ VPumP at time T1, when the second gate line G2 is supplied with a high voltage - Vgh (enable voltage) at time T2, the second gate line G2 The voltage vg(2) will be Vgh plus the previously pulled Vgl Vpump 'vg (2) = Vgl + Vgh + Vpump. In other words, at this time, the second gate line G2 drives the gate of the pixel transistor TFTp with a voltage of 2g Vgl + Vgh + Vpump instead of Vg (2) = Vgl + as in the conventional technique. The voltage of Vgh is driven. Since, in this embodiment, the voltage of the gate of the driving pixel transistor is higher than that of the conventional technology (that is, the pump voltage Vpump is larger than the prior art), The halogen TFT TFTp is turned on faster, so that the liquid crystal in the liquid crystal capacitor Clc will be driven to the desired position more quickly, so that the liquid crystal reaction speed can be accelerated and the scanning time required for the gate line can be shortened. In addition, at T2 During the time, the voltage of the other gate lines receives the low voltage Vgl. Although, during the first time T1, the pixel electrode E of the pixel structure 100 is written with the data signal of the previous pixel, but the time is Very short, in the second time T2, the real data signal of the element is quickly written. In the Τ3 time after the end of the 2nd day, the third gate line & receives the high voltage Vgh, its gate The pole line receives the low voltage tangent. At this time, the first transistor TFT! and the pixel The TFT TFTp is turned off (the 电 implanted state, and the second transistor TFT2 is turned on (On ~), so the chestnut amount Qp stored in the first valley is passed through the first electrode end of the second transistor TF T2 And the discharge of the second electrode end', so that the voltage on the second interrogation line & can be reduced to the original low voltage Vgl, as shown in Fig. 5. <The above-mentioned drive circuit proposed by the present invention can be used In order to drive the pixel's closed-pole voltage, the I-voltage is increased compared with the prior art, so that the pixel TFT 14 201040926 sa TFTP can be turned on faster, and the liquid crystal is moved to the desired position more quickly by the horse. Therefore, it is possible to speed up the display speed of the kneading surface to check the enable time required for the scanning signal of each gate. Therefore, when the display adopts the FSC technology and the side playing frequency is increased by 3 times, the 'drive circuit using the invention' can still be used. Quickly drive the liquid crystal to the desired position, especially for LCD TVs that need to play dynamic pictures, it can effectively break through the bottleneck of the prior art, and solve the problem that the liquid crystal reaction speed of the conventional technology is not fast enough. 〇 [Simple description] Figure 1 is the main BRIEF DESCRIPTION OF THE DRAWINGS Fig. 2 is a timing diagram of a driving device according to a first embodiment of the present invention.
