L ，N與L均為正整數。相反地，於先前技術中，2個 驅動電路（6條掃描線）僅能控制9個發光二極體單元， 顯然本創作之發光二極體電路1可以有效的節省原料 與製造成本。 〔發光二極體電路之另一實施例〕 請參照圖3，圖3係繪示了本創作另一實施例之 發光二極體電路之電路示意圖。如圖3所示，與前一 實施例相同的是，本實施例之發光二極體電路2同樣 具有多條掃描線20、多條掃描線22。與前一實施例不 同的是，本實施例之發光二極體電路2並不具有互相 並聯在一起的發光二極體群組，而是具有多個分散連 10/16 M435017 接在任兩條掃描線之間的發光二極體單元24。 同樣地，本實施例之發光二極體單元24除了可以 耦接在不同群組之掃瞄線之間以外，也可以耦接在相 同群組之掃瞄線之間。舉例來說，在掃描線20a、掃 描線20b可以與掃描線22a、掃描線22b分屬不同的 群組的情況下，本實施例之發光二極體單元240a揭露 了輕接在不同群組之掃猫線之間（掃描線20b與掃描線 22a)的例子，而本實施例之發光二極體單元242a與發 光二極體單元244a都揭露了耦接在相同群組之掃瞄 線之間的例子。也就是說，不論是本實施例或前一實 施例都可以充分地利用任意兩條掃描線來驅動發光二 極體發光，本創作之發光二極體電路2同樣可以有效 的節省原料與製造成本。 值得注意的是，前一實施例之發光二極體群組可 已被預先製做完成，再依照設計者的要求耦接至任兩 條掃描線之間，進而簡化發光二極體電路的製造流程 ，並且加快發光二極體電路的製造速度。在此，雖然 圖3繪示的發光二極體單元24數量與圖3繪示的發光 二極體單元數量相同，但本實施例並不以此為限，即 本實施例之發光二極體單元24不一定要兩兩成對地( 一正接一反接的方式）設置在任兩條掃描線之間，於所 屬技術領域具有通常知識者當然可視需要改變發光二 極體單元24的數量。 綜上所述，本創作之發光二極體電路可以在任意 的兩條掃描線之間設置有兩個極性相反的發光二極體 ，並不限制所述兩條掃描線是否屬於同一個群組。換 11/16 M435017 句話況，本劁邗之發光二極體電路除了可將發光二 體設置在第-掃描線與第H線之間，更可以將# 光二極體設^在兩條第一掃描線之間或者兩條第二ς 描線=間，藉此可以用最少的掃描線驅動最多個發光 以上所述僅為本創作之實施例，其並非用以 本創作之專利範圍。 【圖式簡單說明】 圖1為習知的發光二極體電路之電路示意圖。 圖2係繪示了本創作一實施例之發光二極體電路 路不意圖。 二極體電路之 圖3係繪示了本創作另一實施例之發光 電路示意圖。 【主要元件符號說明】 1 :發光二極體電路 10、10a、10b、12、12a、12b :掃描線 14、140〜149 :發光二極體群組 140a〜149a:第一端 140b〜149b :第二端 1402〜1494 :發光二極體單元 2:發光二極體電路 20、20a、20b、22、22a、22b :掃描線 24 ' 240a〜249a、240b〜249b :發光二極體單 _ SWa〜SWf、SW1 〜SW4 :開關 VCC :高電壓端 GND :低電壓端 12/16 M435017 9 :發光二極體電路 90、90a、90b、90c、92、92a、92b、92c :掃描線 940〜948 :發光二極體單元 13/16M435017 V. New description: [New technical field] This creation relates to a light-emitting diode circuit, and in particular to a light-emitting diode light-emitting diode circuit between any two scanning lines . [Prior Art] 'Polar body is the light source of the widely used light source type~~"η王你~1, in addition to small size, excellent luminous effect, it is more environmentally friendly and energy-saving, so there are many on the market. Light-emitting diodes are widely used in personal lighting equipment, large-scale kanban kanban or backlight source equipment. Generally, in a conventional LED circuit, at least one scan line, a second scan line, and a plurality of light emitting diodes are coupled, and the anode end of the mother light emitting diode is coupled to the first A scan line 'and a cathode end of each of the light-emitting diodes_ are connected to the second scan line ^. In this case, the user can control the working voltage between the first scan line and the second trace, ·, ^• i 'so that the light-emitting diode can be illuminated according to two: and: if the two first scan lines and the two second scan lines are transmitted, four light-emitting diodes are controlled. The number II of the light-emitting diode (for example, the driving circuit of the scanning line) is fixed at 5 times, and the number of scanning lines can control more light: the polar body's cost of the light-emitting diode circuit should be reduced step by step. The scanning line controls more illumination to be set up in the connection mode of Fig. 1. Please refer to Fig. 1, the conventional method, therefore, in order to make the same number of one-pole body, the light-emitting diode circuit 4 of the light diode can be seen on the market. /16 M435017 The photodiode circuit 9 has a plurality of first scan lines 90 ( Parallel scan lines 90a, 90b, 90c), a plurality of second scan lines 92 (such as vertical scan lines 92a, 92b, 92c) and a plurality of light emitting diode groups 940~948. Here, the plurality The LEDs 940 948 can be individually operated according to different coupling scan lines. For example, in the case of the LED group 940, the LED 940 is coupled to the cathode end. The first scan line 90a and the anode end are coupled to the second scan line 92a. When the switch SWa and the switch SWd are both turned on, the operating voltage of the second scan line 92a is raised to a preset high voltage (for example, VCC). When the operating voltage on the first scan line 90a is lowered to a predetermined low voltage (for example, GND), the light emitting diode 940 can be turned on to emit light. In other words, if the same is performed with three first scan lines The light-emitting diode circuits of the three second scanning lines are taken as an example. The light-emitting diode circuit 9 depicted in FIG. 1 can only control 9 light-emitting diodes (the light-emitting diodes 940 to 948 as shown in FIG. 1). In fact, such a light-emitting diode circuit is still not the most efficient way to set the light-emitting diode. There is a need in the industry for a light-emitting diode circuit that can drive a plurality of light-emitting diodes with a minimum of scanning lines when driving a large number of light-emitting diodes. [New content] The present invention provides a light-emitting diode circuit. In addition to disposing the light emitting diode between the first scan line and the second scan line, the light emitting diode may be disposed between the two first scan lines or between the two second scan lines, thereby The plurality of light-emitting diodes can be driven with a minimum of scanning lines. The present invention provides a light-emitting diode circuit including a complex 5/16 M435017 second pole having at least a -first-emission=Aurora two-light one-pole rut The anode end of the first end of the coupling unit and the second end of the second illuminating _ _ _ _ 5 are respectively coupled to the cathode end of the traveler's nine-pole limb, and the fourth (four) is connected to the first light-emitting diode unit. The cathode end i; the anode end of the body unit. Each of the plurality of scanning lines is coupled to the plurality of scanning lines and the other one of the plurality of scanning lines. 〃 The first sorrow is in this creation—the demonstration implementation, which is much more than $: scan line and multiple second scan lines, household = road drive. Here, there are at least one light-emitting diode C=the first end of the plurality of first scan lines, wherein the one end is coupled to one of the plurality of second scan lines; to the three photodiode groups The first end of the group _ the plurality of the first one' and the second end _ the plurality of first scan lines in the white = the first end of the previous light emitting diode group is coupled to the second scan line The other - the younger brother - (four) pick up a lot of singularity's present embodiment of the present invention provides another light-emitting diode circuit, with a plurality of scanning lines and a plurality of light-emitting diode units. There is a light-emitting diode unit between the secrets of the 彡 描 线 线 线 。. In summary, the LED circuit of the present invention can be provided with a light-emitting diode between two scan lines of the tone, and does not limit the $6/16 M435017 eve; ^(4) 疋Μ同同, Then (4), the two-light one-pole circuit can be disposed between the first scan=the first scan line and the scan diode, and the light-emitting diode can be disposed between the “different lines or two second scans”. Between the lines, the most light-emitting diodes can be driven with the least number of scanning lines. 吏 The ability to further understand the characteristics and technical content of this creation, ^金=Details and drawings of this creation, but these The right formula is only used to illustrate the present invention, and is not intended to limit the scope of the present invention. [Embodiment] [Example of Light Emitting Diode Circuit] Referring to Figure 2, Figure 2 shows This creation—the circuit diagram of the double-first diode circuit. As shown in Figure 2, the second-light diode circuit has multiple scans, the scan line ίο, and the green line on the scan line of Figure 2, τΓ 'line coffee, scan line 10b, : The line 12 can be further subdivided into the scanning line 12a and the scanning diode group 14 According to the transfer sweep, the door and the rabbit light diode group Η0~Ι49. The following V diagrams are subdivided into the components of the emitter circuit 1 for detailed description. And being lightly connected to at least one of the driving circuits, so that the ^=12 series respectively generate the plurality of scanning lines through the path (cutting), and the second scanning line is provided to the ^Up' scan line (10), scan line (10) can group (4) scan lines in the twist line group, and control the scan line group for the driver circuit (not shown 7/16 / display) The switch sw], sw 2. The wide line 123 and the scan line 12b can be regarded as the known line in the second scan line group, and are separated by another independent driving circuit (not shown as the # scan line group) In the switch SW3, SW4. Of course,: the creation does not limit the silk axis scan line 1G and the sweep (four) 12: the number of drive circuits 'have a knowledge of the secrets of the knowledge, using time-sharing, partition control sweep line, however It is also possible to control the plurality of scanning lines 1 and scan lines by the same driving circuit. The arrangement direction of the plurality of scan lines 10 and the scans 12 is not limited, that is, the scan lines 10 may be parallel or perpendicular to the scan lines 12, or the scan lines 10 and the scan lines 12 may be formed at any angle. The material, shape and manufacturing method of the plurality of scanning lines 10 and the scanning lines 12 are not limited, as long as the plurality of scanning lines 10 and the scanning lines 12 can be used as conductive wires, which belongs to the scope of the present invention. Those skilled in the art can of course change the material, shape and manufacturing method of the scan line 10 and the scan line 12 as needed. With continued reference to FIG. 2, the plurality of light-emitting diode groups 14 includes a light-emitting diode group. The group 14 〇, the light-emitting diode group 142, the light-emitting diode group 144, the light-emitting diode group 146, the light-emitting diode group 148, and the light-emitting diode group 149. For example, the light emitting diode group 140 can have a first end 40a and a second end i4〇b, the first end 14A is coupled to the scan line i〇b, and the second end 14〇b is coupled to scan. Line 12a. In addition, the LED group 14 includes a light emitting diode unit 1402 and a light emitting diode unit 14〇4<5, the first end 14〇a is coupled to the anode end of the light emitting diode unit 14〇2, respectively. The cathode end of the light-emitting diode 8/16 M435017 body unit 1404 is coupled to the cathode end of the light-emitting diode unit 1402 and the anode end of the light-emitting diode unit 1404, respectively. From a practical point of view, when the switch SW2 is connected to the high voltage terminal and the switch SW3 is connected to the low voltage terminal, the scan line 1 Ob can carry a relatively high operating voltage (for example, VCC), and the scan line 12a It can carry a relatively low operating voltage (such as GND). Here, as long as the operating voltage difference between the scanning line 10b and the scanning line 12a is larger than the ON voltage of the LED unit 1402, the LED unit 1402 is turned on to emit light. On the contrary, when the switch SW2 is connected to the low voltage terminal and the switch SW3 is connected to the high voltage terminal, the scan line 10b can carry a relatively low operating voltage (for example, GND), and can be relatively high on the scan line 12a. Operating voltage (eg VCC). Similarly, if the operating voltage difference applied to the scanning line 12a and the scanning line 1 Ob is larger than the ON voltage of the LED unit 1404, the light-emitting diode unit 1404 is also turned on to emit light. Please note that although the present invention is shown in FIG. 2 as a single LED symbol to represent the LED unit 1402 and the LED unit 1404, the LED unit 1402 is actually illuminated. The polar body unit 1404) may be formed by connecting a plurality of light emitting diodes in series. The difference from the previous case is that the LED circuit 1 of the present invention can be disposed between any two scan lines of the same group (for example, the scan line 10a, the trace 1 Ob, and the scan line 12a, the scan line 12b). Light-emitting diode group〗 4. As can be seen from FIG. 2, the LED group 42 can have a first end 142a and a second end 142b. The first end 142a is coupled to the 9/16 M435017 to the scan line 10a, and the second end 142b is coupled to the scan line. 10b. Thus, the light-emitting diode group 142 exemplifies that the light-emitting diode circuit 1 of the present invention can be provided with two or more of the plurality of scan lines 10 to set the light-emitting diode group. Similarly, the light emitting diode group 144 can have a first end 144a and a second end 144b. The first end 144a is coupled to the scan line 12a, and the second end 144b is coupled to the scan line 12b. Thereby, the light-emitting diode group 144 exemplifies that the light-emitting diode circuit 1 of the present invention can also be disposed in another set of scan lines 12, optionally two to set the light-emitting diode group. In summary, since the LED circuit 1 of the present invention can control 6 groups of light-emitting diodes (ie, 12 light-emitting diode units) by only two driving circuits (four scanning lines), It should be understood by those having ordinary skill in the art that when the sum of the number of all scanning lines is L (for example, 4) and the sum of the number of all the light emitting diode units is N (for example, 12), then N and L may be A relationship is formulated as N = L2 - L , and N and L are positive integers. On the contrary, in the prior art, two driving circuits (six scanning lines) can control only nine light-emitting diode units, and it is obvious that the light-emitting diode circuit 1 of the present invention can effectively save raw materials and manufacturing costs. [Another Embodiment of Light Emitting Diode Circuit] Referring to Figure 3, there is shown a circuit diagram of a light emitting diode circuit according to another embodiment of the present invention. As shown in Fig. 3, the light-emitting diode circuit 2 of the present embodiment also has a plurality of scanning lines 20 and a plurality of scanning lines 22, as in the previous embodiment. Different from the previous embodiment, the LED circuit 2 of the present embodiment does not have a group of LEDs connected in parallel with each other, but has a plurality of decentralized 10/16 M435017 connected to any two scans. Light-emitting diode unit 24 between the lines. Similarly, the LED unit 24 of the present embodiment can be coupled between the scan lines of different groups, and can be coupled between the scan lines of the same group. For example, in a case where the scan line 20a and the scan line 20b can be in different groups from the scan line 22a and the scan line 22b, the LED unit 240a of the present embodiment exposes the light connection in different groups. An example of the scan between the scan lines 20b and the scan line 22a, and the LED unit 242a and the light-emitting diode unit 244a of the present embodiment are both exposed between the scan lines of the same group. example of. That is to say, both the present embodiment and the previous embodiment can fully utilize any two scanning lines to drive the light emitting diode to emit light. The LED diode circuit 2 of the present invention can also effectively save raw materials and manufacturing costs. . It should be noted that the LED group of the previous embodiment can be pre-made and coupled to any two scanning lines according to the designer's requirements, thereby simplifying the manufacture of the LED circuit. The process and speed up the manufacturing of the LED circuit. Here, although the number of the LED unit 24 is the same as that of the LED unit shown in FIG. 3, the embodiment is not limited thereto, that is, the LED of the embodiment. The unit 24 does not have to be arranged in pairs (one way in a reverse connection) between any two scanning lines, and those skilled in the art can of course change the number of the light-emitting diode units 24 as needed. In summary, the LED circuit of the present invention can provide two LEDs with opposite polarities between any two scan lines, and does not limit whether the two scan lines belong to the same group. . For 11/16 M435017, in addition to the light-emitting diode system, the light-emitting diode can be placed between the first scan line and the H-th line, and the #-light diode can be set in two Between one scan line or two second lines = between, whereby the most illuminating can be driven with a minimum of scan lines. The above-described embodiments are merely examples of the present invention, and are not intended to be used in the scope of the patent.
