On the lower surface of the glass substrate 102, a plurality of scanning electrodes (hereinafter referred to as common electrodes 108) formed of an ITO film are formed so as to vertically intersect the segment electrodes 107.

各節段電極107,係藉由被形成於下側玻璃基板101上之訊號線109而與驅動用IC104連接,各共通電極108,亦同樣藉由被形成於下側玻璃基板101上之訊號線109;和連接於此訊號線109而使下側玻璃基板101與上側玻璃基板102之間相互導通的上下玻璃導通材110;和連接各上下玻璃導通材110與共通電極108之訊號線109,而與驅動用IC104相連接。又,此些之各訊號線109,係和各節段電極107以及各共通電極108同樣的藉由ITO膜而形成。又,驅動用IC104,係藉由被形成於下側玻璃基板101上之由ITO膜所成的訊號線109,而連接於可撓性基板111,藉由被形成於此可撓性基板111上之配線,與未圖示之控制部相連接。同樣地,背光用LED105,亦經由被形成於可撓性基板111上之配線,而與控制部相連接。Each segment electrode 107 is connected to the driving IC 104 by a signal line 109 formed on the lower glass substrate 101, and each common electrode 108 is also formed by a signal line formed on the lower glass substrate 101. And an upper and lower glass conductive material 110 connected to the signal line 109 to electrically connect the lower glass substrate 101 and the upper glass substrate 102; and a signal line 109 connecting the upper and lower glass conductive materials 110 and the common electrode 108, and It is connected to the driving IC 104. Further, each of the signal lines 109 is formed of an ITO film similarly to each of the segment electrodes 107 and the common electrodes 108. Further, the driving IC 104 is connected to the flexible substrate 111 by the signal line 109 formed of the ITO film formed on the lower glass substrate 101, and is formed on the flexible substrate 111. The wiring is connected to a control unit (not shown). Similarly, the backlight LED 105 is also connected to the control unit via the wiring formed on the flexible substrate 111.

Display area 112.

在如此這般所構成之液晶顯示裝置100中,在使背光用LED105發光的狀態下,藉由從控制電路所輸入之控制訊號來驅動驅動用IC104,並藉由從驅動用IC104而對各節段電極107以及各共通電極108在特定之時序所輸入之驅動訊號,來在所期望之節段電極107與共通電極108之間產生特定之電位差,並藉由使產生有電位差之部分的位置於節段電極107與共通電極108間之交叉點的液晶之方向產生變化,而調節各畫素部分之亮度,並在顯示區域112內顯示畫像。In the liquid crystal display device 100 configured as described above, the driving IC 104 is driven by the control signal input from the control circuit while the backlight LED 105 is being turned on, and the sections are driven from the driving IC 104.

然而,於上所述之先前的液晶顯示裝置,由於係具備有用以保護驅動用IC104使其免於受到衝擊的金屬框114,因此當產生有起因於將驅動用IC104與液晶面板103作連接之訊號線109的斷線所造成之問題時,為了調查其原因,必須要進行非常繁雜的作業。亦即是,就算是如同上述之液晶顯示裝置100一般,具備有矽材113或金屬框114的液晶顯示裝置100,亦會有由於使用中之振動或衝擊而造成玻璃基板破損之虞。特別是,在下側基板101中,於被形成有將驅動用IC104與液晶面板103作連接的訊號線109之部分,由於係為未與上側玻璃基板102相重疊之部分,因此強度係低,如圖6所示,會有從此角部而產生有龜裂117之虞。However, in the prior liquid crystal display device described above, since the metal frame 114 is provided to protect the driving IC 104 from the impact, the driving IC 104 and the liquid crystal panel 103 are connected. When the problem of the disconnection of the signal line 109 is caused, in order to investigate the cause, it is necessary to perform a very complicated operation. That is, even in the liquid crystal display device 100 as described above, the liquid crystal display device 100 including the coffin 113 or the metal frame 114 may cause damage to the glass substrate due to vibration or impact during use. In particular, in the lower substrate 101, the portion of the signal line 109 on which the driving IC 104 and the liquid crystal panel 103 are connected is formed so as not to overlap with the upper glass substrate 102, so that the strength is low, such as As shown in Fig. 6, there is a flaw in which cracks 117 are generated from the corners.

如此這般,若是在下側玻璃基板101中,被配置有驅動用IC104之部分的角部產生有龜裂117,則連接驅動用IC104與液晶面板103之訊號線109則會斷線,使得無法從驅動用IC104將驅動訊號輸入液晶面板103,而產生無法在顯示區域112將畫像作顯示的問題。但是,如上述所示,由於此訊號線109之斷線部分,係被金屬框114所被覆,因此無法從外部來確認斷線,為了調查問題的原因,必須要將金屬框114從液晶面板103取下,並更進而必須以目視來確認下側玻璃基板101之龜裂117以及細微之訊號線109的斷線,因此其作業係為繁雜。When the crack 117 is formed in the corner portion of the portion of the lower glass substrate 101 where the driving IC 104 is disposed, the signal line 109 connecting the driving IC 104 and the liquid crystal panel 103 is disconnected, so that the signal line 109 is disconnected. The driving IC 104 inputs the driving signal to the liquid crystal panel 103, causing a problem that the image cannot be displayed in the display area 112. However, as described above, since the broken portion of the signal line 109 is covered by the metal frame 114, the disconnection cannot be confirmed from the outside, and in order to investigate the problem, the metal frame 114 must be removed from the liquid crystal panel 103. Further, it is necessary to visually confirm the breakage of the crack 117 of the lower glass substrate 101 and the fine signal line 109, so that the operation is complicated.

於此,在本發明中,作為特徵,係在具備有將資訊作顯示之顯示部,以及輸入驅動顯示部之驅動訊號的配線部之顯示裝置中,具備有:當在配線部中之訊號線斷線時,會與其共同斷線的斷線檢測用配線。In the present invention, a display device including a display unit for displaying information and a wiring portion for driving a drive signal for driving the display unit is provided with a signal line in the wiring portion. When the wire is disconnected, the wire for disconnection detection that will be disconnected with it is broken.

In the signal wiring of the plurality of signals, when the signal wiring of at least one of the signal wirings at both ends is broken, the disconnection is performed together with the signal wiring. The disconnection detecting wiring includes a first detecting wiring which is a signal wiring along one of the signal wirings at both ends, and is positioned closer to the outside of the substrate than the signal wiring. And the second detecting wiring is disposed along the other signal wiring so as to be positioned outside the substrate than the signal wiring; and the conductive wiring is formed on the substrate The first detecting wiring and the second detecting wiring are electrically connected to each other. Further, the first disconnection detecting terminal electrically connected to the first detecting wiring and the second disconnecting detecting terminal electrically connected to the second detecting wiring are provided, and The resistance value between the disconnection detecting terminal of the first line and the second disconnection detecting terminal is such that the disconnection of the signal wiring can be detected.

於此,絕緣體係為以與基板相對向之方式所設置的對向基板,在基板與對向基板之間,係具備有:連接第1的檢測用配線與導通配線之導電材;和連接第2的檢測用配線與導通配線之導電材。Here, the insulating system is a counter substrate provided to face the substrate, and a conductive material for connecting the first detecting wiring and the conducting wiring is provided between the substrate and the counter substrate; and 2, the detection wiring and the conductive material of the conduction wiring.

於基板上係被連接有可撓性基板,第1及第2的斷線檢測用端子,係被形成於此可撓性基板上。又,於基板上係被安裝有輸出驅動訊號的驅動IC,前述之複數的配線,係連接於驅動IC之輸出端子。A flexible substrate is connected to the substrate, and the first and second disconnection detecting terminals are formed on the flexible substrate. Further, a driving IC for outputting a driving signal is mounted on the substrate, and the plurality of wirings are connected to an output terminal of the driving IC.

如此這般,本發明之顯示裝置,係具備有:用以顯示畫像資訊或是文字資訊等之資訊的顯示部;和被形成有將用以驅動此顯示部之驅動訊號輸入至該顯示部的訊號配線之配線部。並且,此顯示裝置,係具備有用以檢測出因衝擊等所致之配線部中的訊號配線之斷線所導致的顯示部之問題的斷線檢測用配線。此斷線檢測用配線,當訊號配線斷線時,係被構成為與訊號配線共同斷線,而藉由檢查此斷線檢測用配線之導通狀態,成為能檢測出訊號配線之斷線。因此,不需要藉由直接目視來確認訊號配線本身之斷線,而可容易地檢測,並能不進行繁雜之作業,即可檢測出因訊號配線之斷線所造成之顯示裝置的問題之原因。In this manner, the display device of the present invention is provided with a display portion for displaying information such as portrait information or text information, and a driving signal for driving the display portion to be input to the display portion. Wiring part of signal wiring. In addition, the display device includes a disconnection detecting wiring for detecting a problem of the display portion due to disconnection of the signal wiring in the wiring portion due to an impact or the like. When the signal wiring is disconnected, the disconnection detecting wiring is configured to be disconnected from the signal wiring, and by detecting the conduction state of the disconnection detecting wiring, the disconnection of the signal wiring can be detected. Therefore, it is not necessary to directly confirm the disconnection of the signal wiring itself by direct visual observation, and it is possible to easily detect and detect the problem of the display device caused by the disconnection of the signal wiring without performing complicated operations. .

又,斷線檢測用配線,係藉由沿著在訊號配線中容易產生斷線之一部分,又或是沿著訊號配線之全體而配設,而構成為可在訊號配線斷線時同時成為斷線。進而,此斷線檢測用配線,係具備有斷線檢測用端子,其係藉由在基端側與終端側,分別檢測出斷線檢測用配線之斷線,而成為可檢測出訊號配線之斷線。而,在進行斷線之檢查時,在此一對之斷線檢測用端子間,施加斷線檢測用之特定電壓,並根據此時之斷線檢測用端子間的導通電阻值,判斷是否有斷線。亦即是,當在斷線檢測用端子間施加特定之電壓後,若是斷線檢測用端子間之導通電阻值係成為無限大,則可判斷其係為斷線,而當斷線檢測用端子間之導通電阻值係成為非常低的特定值(藉由斷線檢測用配線之材料、形狀所決定的固有值)時,則可判斷其並未斷線。Further, the disconnection detecting wiring is configured to be easily broken along the signal wiring, or along the entire signal wiring, and is configured to be disconnected at the same time when the signal wiring is broken. line. Further, the disconnection detecting wiring includes a disconnection detecting terminal that detects disconnection of the disconnection detecting wiring on the proximal end side and the terminal side, and detects the signal wiring. Broken line. In the case of the disconnection check, a specific voltage for disconnection detection is applied between the pair of disconnection detecting terminals, and based on the on-resistance value between the disconnection detecting terminals at this time, it is determined whether or not There is a broken line. In other words, when a specific voltage is applied between the terminals for detecting the disconnection, if the on-resistance value between the terminals for disconnection detection is infinite, it can be judged that the disconnection is broken, and when the disconnection is detected, When the on-resistance value between the terminals is a very low specific value (the eigenvalue determined by the material and shape of the wire for disconnection detection), it can be judged that the wire is not broken.

如此這般,僅需在一對的斷線檢測用端子間施加特定的電壓,即可不藉由目視而容易地檢測出訊號配線之斷線。又,斷線檢測用端子,係成為被設置在與將驅動訊號輸入至顯示部的配線部相連接之可撓性基板上。可撓性基板,由於係具備有可撓性,因此藉由在此可撓性基板上設置斷線檢測用配線,能提升在顯示裝置之筐體內部的斷線檢測用配線之處理的自由度,就算是不分解顯示裝置,亦可在可施加用以檢查斷線之電壓的場所設置斷線檢測用端子,因此成為能容易地檢測出訊號配線之斷線。In this manner, it is only necessary to apply a specific voltage between the pair of disconnection detecting terminals, so that the disconnection of the signal wiring can be easily detected without visual observation.

而,此液晶顯示裝置1,係具備有:當用以從驅動IC5將驅動訊號輸入至液晶面板4的訊號配線10斷線時,用以檢測此斷線之斷線檢測用配線18。此斷線檢測用配線18,係如圖1所示,藉由:在下側玻璃基板2上,沿著連接驅動用IC5與導通材11之訊號配線而配設之第1的斷線檢測部19a以及第2的斷線檢測部19b;和在上側玻璃基板3上,將被設置於此些之第1的斷線檢測部19a與第2的斷線檢測部19b之各端部上的導通材11a彼此相互連接之聯絡部20;和被連接於各斷線檢測部19a、19b,而被形成於可撓性基板12上之第1金屬配線21a以及第2金屬配線21b所構成。另外,為了說明上的方便,係將第1金屬配線21a側作為基端側,而將第2金屬配線21b側作為終端側來說明。In the liquid crystal display device 1, the disconnection detecting wiring 18 for detecting the disconnection when the signal wiring 10 for inputting the driving signal from the driving IC 5 to the liquid crystal panel 4 is disconnected is provided. As shown in FIG. 1, the disconnection detecting wiring 18 is a first disconnection detecting portion 19a disposed on the lower glass substrate 2 along the signal wiring connecting the driving IC 5 and the conductive material 11. And a second disconnection detecting portion 19b; and a conductive material provided on each end portion of the first disconnection detecting portion 19a and the second disconnecting detecting portion 19b of the upper glass substrate 3 The communication portion 20 to which the 11a is connected to each other and the first metal interconnection 21a and the second metal interconnection 21b which are formed on the flexible substrate 12 are connected to the respective disconnection detecting portions 19a and 19b. In addition, for convenience of explanation, the side of the first metal wiring 21a is referred to as a base end side, and the side of the second metal wiring 21b is referred to as a terminal side.

如此這般,在第1斷線檢測部19a以及第2斷線檢測部19b中之斷線檢測用配線18,由於係在下側玻璃基板2上,沿著從驅動IC5將驅動訊號輸入至液晶面板4的訊號配線10,而被配設於基板之外側,因此當沿著此斷線檢測用配線18而配設之訊號配線10斷線時,係成為同時斷線(參考圖3)。因此,經由檢測出在第1斷線檢測部19a與第2斷線檢測部19b中之斷線檢測用配線18是否有斷線,而可間接地檢測出訊號配線10是否有斷線。In this manner, the disconnection detecting wiring 18 in the first disconnection detecting unit 19a and the second disconnection detecting unit 19b is connected to the lower glass substrate 2, and the driving signal is input to the liquid crystal panel along the driving IC 5. Since the signal wiring 10 of the fourth embodiment is disposed on the outer side of the substrate, when the signal wiring 10 disposed along the disconnection detecting wiring 18 is disconnected, the simultaneous disconnection is performed (refer to FIG. 3). Therefore, it is possible to indirectly detect whether or not the signal wiring 10 is disconnected by detecting whether or not the disconnection detecting wiring 18 in the first disconnection detecting unit 19a and the second disconnection detecting unit 19b is disconnected.

又,第1金屬配線21a以及第2金屬配線21b,係設置於被形成有由未圖示之控制部而將控制訊號輸入驅動用IC5之配線的可撓性基板12上,而在其端部,具備有被施加用以檢測斷線之特定電壓的第1斷線檢測用端子22a與第2斷線檢測用端子22b。又,可撓性基板12,係具備有可撓性,而如圖2所示,其一端側係藉由被形成於下面玻璃基板2之上面的訊號配線10,而經由驅動IC5連接於液晶面板4,另外一端側,係成為被折彎至液晶顯示裝置1之下面側的狀態。而後,在被折彎之可撓性基板12的內周面,形成身為斷線檢測用配線18之一部分的第1金屬配線21a與第2金屬配線21b,同時在液晶顯示裝置1之下面側中的可撓性基板12的外周面,設置第1斷線檢測用端子22a與第2斷線檢測用端子22b,並將此些之第1斷線檢測用端子22a以及第2斷線檢測用端子22b與斷線檢測用配線18,藉由貫通可能性基板12之通孔而相互連接。In addition, the first metal interconnection 21a and the second metal interconnection 21b are provided on the flexible substrate 12 on which the control signal is input to the control IC 5 and is formed by a control unit (not shown). The first disconnection detecting terminal 22a and the second disconnection detecting terminal 22b to which a specific voltage for detecting a disconnection is applied are provided. Further, the flexible substrate 12 is flexible, and as shown in FIG. 2, one end side is connected to the liquid crystal panel via the drive IC 5 via the signal wiring 10 formed on the upper surface of the lower glass substrate 2. 4. The other end side is in a state of being bent to the lower side of the liquid crystal display device 1. Then, the first metal wiring 21a and the second metal wiring 21b which are part of the disconnection detecting wiring 18 are formed on the inner peripheral surface of the bent flexible substrate 12, and the lower surface side of the liquid crystal display device 1 is formed. The first disconnection detecting terminal 22a and the second disconnection detecting terminal 22b are provided on the outer peripheral surface of the flexible substrate 12, and the first disconnection detecting terminal 22a and the second disconnection detecting terminal are provided. The terminal 22b and the disconnection detecting wiring 18 are connected to each other by a through hole penetrating through the possible substrate 12.

於此,針對在此液晶顯示裝置1中,進行連接驅動IC5與液晶面板4的訊號配線10之是否斷線的檢測方法作說明。首先,在任意的兩端子間施加特定之電壓,並準備可測定此兩端子間之導通電阻值的測試器(省略圖示)。而後,將此測試器所具備的一對之測試端子的其中一方,連接於第1斷線檢測用端子22a,同時將另外一方連接於第2斷線檢測用端子22b。而後,在一對的測試用端子之間施加特定的電壓,並測定此時之第1斷線檢測用端子22a與第2斷線檢測用端子22b之間的導通電阻值。此時,如圖1所示,當連接驅動IC5與液晶面板4之訊號配線10未被切斷時,藉由測試器所致之測定結果係成為斷線檢測用配線18所具備之固有的電阻值。另一方面,如圖3所示,當在下側玻璃基板2之角部產生龜裂23,而斷線檢測用配線18與訊號配線10一同斷線時,測試器所致之測定結果係成為無限大。In the liquid crystal display device 1, a method of detecting whether or not the signal wiring 10 of the driving IC 5 and the liquid crystal panel 4 is disconnected is described. First, a specific voltage is applied between any two terminals, and a tester (not shown) capable of measuring the on-resistance between the two terminals is prepared. Then, one of the pair of test terminals included in the tester is connected to the first disconnection detecting terminal 22a, and the other one is connected to the second disconnection detecting terminal 22b. Then, a specific voltage is applied between the pair of test terminals, and the on-resistance value between the first disconnection detecting terminal 22a and the second disconnection detecting terminal 22b at this time is measured. At this time, as shown in FIG. 1, when the signal wiring 10 that connects the drive IC 5 and the liquid crystal panel 4 is not cut, the measurement result by the tester is an inherent resistance of the disconnection detection wiring 18. value. On the other hand, as shown in FIG. 3, when the crack 23 is generated at the corner of the lower glass substrate 2, and the disconnection detecting wiring 18 is disconnected together with the signal wiring 10, the measurement result by the tester becomes infinite. Big.

如此這般,在此液晶顯示裝置1中,可將起因於下側玻璃基板2之破損所造成的細微之訊號配線10的斷線,不經由目視,而藉由以測試器所檢測出之第1斷線檢測用端子22a與第2斷線檢測用端子22b之間的導通電阻值,而可容易地檢測出來。並且,如上述一般,由於在斷線檢測用配線18之基端側設置有第1斷線檢測用端子22a,同時在斷線檢測用配線18之終端側設置有第2斷線檢測用端子22b,並將此第1斷線檢測用端子22a與第2斷線檢測用端子22b配置於液晶顯示裝置1之下面側,因此在將測試器之測試用端子連接至第1斷線檢測用端子22a與第2斷線檢測用端子22b時,並不需要進行從液晶面板4將金屬框15卸下的作業,而能容易地進行斷線檢測作業。In this manner, in the liquid crystal display device 1, the disconnection of the fine signal wiring 10 caused by the damage of the lower glass substrate 2 can be detected by the tester without visual inspection. The on-resistance value between the disconnection detecting terminal 22a and the second disconnection detecting terminal 22b can be easily detected. In addition, as described above, the first disconnection detecting terminal 22a is provided on the proximal end side of the disconnection detecting wiring 18, and the second disconnection detecting terminal 22b is provided on the terminal side of the disconnection detecting wiring 18. The first disconnection detecting terminal 22a and the second disconnection detecting terminal 22b are disposed on the lower surface side of the liquid crystal display device 1. Therefore, the test terminal of the tester is connected to the first disconnection detecting terminal 22a. When the second disconnection detecting terminal 22b is used, it is not necessary to perform the work of removing the metal frame 15 from the liquid crystal panel 4, and the disconnection detecting operation can be easily performed.

又,於此,在下側玻璃基板2中,經由在未與上側玻璃基板3重合而機械強度較低的部分,選擇性地設置斷線檢測用配線18之第1斷線檢測部19a與第2斷線檢測部19b,而能盡可能地減短斷線檢測用配線18之長度,藉由此,能抑制此液晶顯示裝置1之製造成本的增大。In addition, in the lower glass substrate 2, the first disconnection detecting unit 19a and the second disconnection detecting wiring 18 are selectively provided in a portion where the mechanical strength is not overlapped with the upper glass substrate 3, and the second disconnection detecting portion 18 is selectively provided. In the disconnection detecting unit 19b, the length of the disconnection detecting wiring 18 can be shortened as much as possible, whereby an increase in the manufacturing cost of the liquid crystal display device 1 can be suppressed.

如以上所說明,若藉由本發明,則不需要繁雜之作業,即可容易且迅速的判斷出顯示部所產生之問題的原因,是否為基板之破損所造成的訊號配線之斷線,並且,如上述之變形例一般亦能檢測出基板周圍邊緣部的破損。As described above, according to the present invention, it is possible to easily and quickly determine the cause of the problem occurring in the display unit without requiring complicated work, and whether or not the signal wiring is broken due to breakage of the substrate, and As described above, the damage of the peripheral edge portion of the substrate can be generally detected.

另外,在本實施例中,雖係舉出被動驅動方式的顯示裝置作為具體例,但是不用說,本發明亦可通用於主動驅動方式之顯示裝置。Further, in the present embodiment, a passive driving type display device is exemplified as a specific example, but needless to say, the present invention can also be applied to an active driving type display device.
