Green light-through module.渰曰缺如# and day control components include some liquid placed between the first element electrode, the first common electrode placed on the first substrate of the first 士〇, and the liquid S between the pole and the common electrode (10) Day. The number of halogen electrodes is equivalent to Shoudan", and the electrode is placed on the opposite side of the halogen electrode. Each of the electrodes/TFTs is applied to the common electrode with a reference voltage applying a different voltage to the 昼_ equipotential. The halogen electrode and the 'hometown' are composed of a transparent conductor material. The light provided by the backlight module sequentially passes through the halogen electrode, the liquid, and the electrode. The image display quality through the liquid crystal is closely related to the uniformity of the backlight module. In general, the brightness and brightness are uniform and the display quality is better. In the conventional LCD device, the backlight module is connected to a cold cathode fluorescent lamp tube (c〇ld cathode fluorescent lamp group, and the surface optical optical device is not, the liquid crystal liquid crystal panel has a morphoelectricity, and the electrode is connected to the electrode. The electrodes, and the higher the degree of commonality and brightness, use the rod CCFL) 5 200836226 or point-shaped light-emitting diode (LED). Compared to incandescent lamps, CCFLs have high brightness, long life, and low heat generation. Led consumes more power but has a higher brightness. However, neither the CCFL nor the LED has a uniform brightness uniformity. In order to improve brightness uniformity, an optical component such as a light guide plate (LGP), a diffusion member, and a cymbal sheet are required for a backlight module using a CCFL or an LED as a light source. Therefore, an LCD device using an optical member such as a CCFL or an LED becomes cumbersome. Therefore, it is recommended to use a planar surface light source component as a light source for an LCD device. Referring to Fig. 1, a conventional surface light source element includes a light source body 1 and an electrode 20 provided on both sides of the light source body 10. The light source body 10 includes a first substrate and a second substrate spaced apart by a certain distance. A plurality of spacers 30 are arranged between the first and second substrates, and divide the internal spaces defined by the first and second substrates into a plurality of discharge spaces 50. A sealing member 40 is disposed between the edges of the first and second substrates to separate the discharge space 50 from the outside. A discharge gas is injected into the isolated discharge space 50. The electrode 20 is provided in the form of a strip on the surface of the light source body 10 such that the area covering each of the discharge spaces 50 is the same. The inverter applies a discharge voltage to the discharge space 50. All discharge spaces are uniformly discharged. Due to the response characteristics of the liquid crystal display, the liquid crystal display device has a residual image problem. The afterimage of the moving graphics will reduce the display quality. As liquid crystal display devices become larger and larger, the requirements for display quality are also increasing. Various ways to solve the problem of the problem have emerged, but they are still not perfect. The liquid crystal display device still has a problem that the backlight module consumes too much power. Therefore, 6 200836226 urgently need to reduce power consumption. In addition, conventional fluorescent lamps usually use mercury as a discharge gas. In view of environmental considerations (such as the Restriction of Hazardous Substances (R〇Hs), there is an urgent need for mercury-free lamps. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a surface light source element and a backlight module having the same, thereby improving the display quality of the liquid crystal display device. Another object of the present invention is to provide a surface light source component and a backlight module having the same, thereby reducing the total power consumption. Still another object of the present invention is to provide a surface light source element and a backlight module that are suitable for driving a surface light source element that does not use mercury as a discharge gas. According to an aspect of the present invention, a surface light source component includes: a light source body having an internal space containing a discharge gas; and a plurality of electrodes disposed on the light source body to electrically separate the internal space into at least three a block, and applying a discharge voltage to the block; and a driving unit that sequentially applies a discharge voltage to the block by the electrode and synchronizes with the video of an external display device. Electrodes can be placed at both ends of the block, and the drive unit can apply an inverting voltage to both ends of the block. The light source body may contain a plurality of discharge spaces or a single discharge space. The electrodes may be partially disposed on an outer surface or two outer surfaces of the light source body. The electrodes may be provided on a plurality of outer surfaces or two outer surfaces in the form of a plurality of surface electrodes having a high aperture ratio. According to another aspect of the present invention, the present invention provides a backlight module, package 7

According to the present invention, since the surface light source element has a plurality of blocks sequentially applying a discharge voltage to the block, the liquid crystal display production can be reduced. Furthermore, since the surface light source element is driven by the partition, the power consumption can be reduced, the service life can be extended, and the image quality can be improved. [Embodiment] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. A first feature of the present invention is that the internal null of the surface light source elements is actually or non-actually separated (by electrodes) into a plurality of blocks, and voltage partitions are sequentially applied to the blocks. Further, the second characteristic name of the present invention, the discharge voltage is applied to the block in synchronism with the video of the liquid crystal display device, whereby the residual image of the liquid crystal display can be effectively reduced. Figure 2 is a block diagram of a drive unit in accordance with the present invention for a surface light source component. The driving unit includes a synchronizing circuit, a sequential driving control unit, and an inverter. The synchronizing circuit synchronizes the video of the discharge liquid crystal display (LCD) panel applied to the discharge space. The sequential drive control mode synchronizes the discharge voltage with the scanning signal of the video, and sequentially applies the internal discharge of the discharge and the surface to the surface, and the discharge is clear. The drive is single voltage and the special discharge 8 200836226 Block. The sequential drive control unit can be a stand-alone circuit or integrated into an inverter. Fig. 3 is a perspective view of a surface light source element according to a first embodiment of the present invention. The light source body includes a first substrate i and a second substrate i 2 . The sealing member at the edge of the light source body separates the inner space and the outer portion between the first and second substrates 11A, 12B. The partition 30 divides the internal space into a plurality of discharge spaces 140. The electrodes 151 to 154, 161 to 164 are provided on the outer surface of the surface light source element corresponding to the discharge space. A pair of electrodes are disposed at both ends of each discharge space. The electrodes may be provided on an outer surface or two outer surfaces of the surface light source elements. The discharge voltage is sequentially applied to the discharge space 140 through the electrodes 151 to 154, 161 to 164. Here, for example, the discharge space (constituting the first block) to which the first discharge voltage is applied may partially overlap and apply the second discharge. The discharge space of the voltage (constituting the second block). In the present invention, the discharge voltage may have a square wave waveform or a pulse waveform. 4A to 4C are graphs showing pulse width modulation (ρψΜ), and 4D and 4E are diagrams showing voltage waveforms applied to the surface light source elements according to the present invention. Referring to Fig. 4A and Fig. 3 together, for example, the discharge voltage can be sequentially applied to the first to fourth discharge spaces of the surface light source element of Fig. 3 in accordance with the following indication. The first discharge voltage is applied to the first discharge space 1 4 利用 by the first electrode 15 161 and according to the first PWM signal S 1 . Next, the second discharge voltage is applied to the second discharge space 14A by the second electrodes 152, 162 and according to the second PWM signal S2. 9 200836226 Then 'the third discharge voltage uses the third electrode! 53, 163 and three PWM signals S3 are applied to the third discharge space ι4 〇. Then, the fourth discharge voltage is applied to the fourth discharge space ι4 利用 by the fourth electrodes 154, 164 and the four PWM signals S4, at which time one cycle of the discharge voltage is completed. In this way, the surface light source elements are sequentially emitted to emit light, which has less image sticking and improved image quality. The invention invents the internal space of the surface light source element into three blocks, preferably one or four or more blocks, which are sequentially applied to the block to reduce image sticking. The discharge voltage can be driven by multiple drive units or a single common drive. The sequential drive control unit provides synchronization with the vertical frequency of the video. The PWM signal is used to cause the light source element to emit light in synchronization with the vertical frequency of the video. Therefore, once the scanning signal is applied to a portion of the liquid crystal display device, the surface light source element locally provides local line time from the back side. Then, in another period of time, if the local area is not provided, it is like inserting a black image between the actual images, so that the image can be improved to maximize the driving force of the order, as shown in Fig. 4A, the end point of the p WM signal S 1 It can coincide with the start of the external video vs (the vertical frequency of the liquid crystal display). This is more effective in reducing the residual image of the liquid. The duty ratio of the pulse width modulation signal is preferably a light of a certain area of the sequence according to the first application of the voltage reduction or more. ? Oral quality. The first display is equipped with crystal display $ 5 0% or 10 200836226 less to effectively reduce the afterimage. In addition, the video brightness can change the energy ratio to improve the image contrast. For example, referring to Figure 4B, the energy rate of cycle 1 (energy rate ratio is 40-50%) and period π (energy rate ratio is 10-20%) is 5 weeks change depending on external video VS, such surface The light source element will produce different illumination during period 1 (bright image) and period 11 (dark image). ^ The surface light source component adjusts the pulse width modulation signal energy ratio between 1〇_5〇% (between 'to reduce the residual image. The brightness of the surface light source component is controlled by video. This can reduce the total power consumption and greatly Improve the image quality of the liquid crystal display device. Further, by applying a voltage pulse with a fixed pulse width modulation signal rate ratio during the on-duty period, the image sticking can be effectively reduced. Referring to FIG. 4C, the vertical frequency is 60. Hertz (Hz), the pulse width modulation signal rate ratio is fixed at -40%, and the voltage pulse (b) applied during the value period is 1 kHz or more. The voltage of 1 kHz or more is applied during the value. The number of pulses can be viewed

This can effectively reduce image sticking and improve image quality. The surface light source element according to the present invention can be driven by a pulse waveform voltage or a square wave waveform voltage. If the surface light source element is driven by a pulse waveform voltage, its frequency is preferably 20 6 kHz and the on-time is preferably 0.1-10 microseconds (Ms). The shorter the on-time is, the faster the discharge rise time is, so the higher the efficiency of the surface light source element. The 4D and 4E diagrams respectively show examples of discharge voltage waveforms generated by the half bridge inverter and the full bridge inverter 11 200836226, wherein the on time is 〇·1_1 Ops. As described above, the discharge voltage having this waveform is applied during the value period. In the present invention, a plurality of electrodes are provided at both ends of the discharge space. In this example, the driving unit applies an inverting voltage to the electrodes at both ends. That is, the voltage phase applied to one of the electrodes is low, and the phase of the voltage applied to the other electrode is high, so that the sum of the voltages applied to the discharge space becomes twice. The gap of the electrode can be wider than the gap of the discharge space, so as to prevent the discharge voltage applied to a certain block from being improperly applied to other adjacent blocks C 1 while sequentially driving f. Referring to Fig. 5, the gap between the electrode 161 and the electrode 16 2 is wider than the gap of the discharge space (e.g., the width of the spacer 13 3 第 in Fig. 5). The gap W of the electrode can vary depending on the gap of the discharge space. 6 and 7 illustrate a surface light source element 200 in accordance with a second embodiment of the present invention. The surface light source element 200 includes a light source body 2 10 and a plurality of electrodes 251 to 254, 261 to 264 provided on both sides of the outer surface of the light source body 210. The light source body 210 includes a first substrate 212 and a second substrate 214, both of which are disposed face to face and separated by a certain distance. The partition 22 5 divides the internal space defined by the first and second base plates 212, 214 into a plurality of discharge spaces 240. The spacer 225 and the via 220 can be formed, for example, by molding the first substrate 212 and/or the second substrate 214. A seal 230 is disposed between the edges of the first and second substrates 212, - 214. The discharge gas is injected into the discharge space 240.
