Description

顯示裝置與顯示面板 Display device and display panel

本發明是有關於一種顯示裝置與顯示面板,且特別是有關於一種具有不同電極間距的顯示裝置與顯示面板。 The present invention relates to a display device and a display panel, and more particularly to a display device and a display panel having different electrode spacings.

為了因應消費大眾之需求,顯示器相關業者紛紛投入具有快速應答特性之藍相(blue phase)液晶顯示器的開發。以藍相(blue phase)液晶材料為例,一般需要橫向電場來進行操作以使其具有光閥之功能。目前已經有人採用共面轉換IPS(In-Plane Switching)顯示模組之電極設計來驅動藍相(blue phase)液晶顯示器中的藍相液晶分子。 In response to the demand of the consumer, display-related operators have invested in the development of blue phase liquid crystal displays with fast response characteristics. Taking a blue phase liquid crystal material as an example, a transverse electric field is generally required to operate to have the function of a light valve. At present, the electrode design of the IPS (In-Plane Switching) display module has been used to drive blue phase liquid crystal molecules in a blue phase liquid crystal display.

雖然藍相液晶具有快速應答時間與光學等向性等優點,但卻有驅動電壓較高的缺點,其驅動電壓通常需高達55伏。此外,具有平面轉換型之畫素單元的藍相液晶顯示面板,其條狀圖案所佔據的區域為暗區D,使得藍相液晶顯示面板的穿透率不佳。因此,採用藍相液晶為顯示介質的顯示裝置或顯示面板的設計仍有改善的空間。 Although blue phase liquid crystal has the advantages of fast response time and optical isotropicity, it has the disadvantage of high driving voltage, and its driving voltage usually needs to be as high as 55 volts. Further, in the blue phase liquid crystal display panel having the planar conversion type pixel unit, the area occupied by the strip pattern is the dark area D, so that the transmittance of the blue phase liquid crystal display panel is not good. Therefore, there is still room for improvement in the design of a display device or a display panel using a blue phase liquid crystal as a display medium.

本發明提供一種顯示裝置及其顯示面板,利用不同電極間距以產生良好穿透率並解決其色偏問題。 The invention provides a display device and a display panel thereof, which utilize different electrode spacings to generate a good transmittance and solve the color shift problem thereof.

The first pixel unit, the second pixel unit and the third pixel unit respectively comprise a first substrate, a second substrate, a color filter layer and a display medium. The foregoing first substrate has a plurality of first electrodes and a plurality of second electrodes arranged alternately with each other, wherein each of the first electrodes and the adjacent second electrodes have an equidistant spacing therebetween.

基於上述,本發明的顯示裝置以及顯示面板中,不同電極組之間具有不同的間距,以產生不同大小的電場。在顯示裝置中,利用此不同的間距所產生之不同大小的電場驅動不同的光源組,以改善顯示裝置的穿透率以及色偏的問題。另外,在本發明的顯示面板中,利用此不同的間距所產生之不同大小的電場驅動不同的畫素單元,同樣可達到改善顯示面板的穿透率以及改善色偏問題的效果。 Based on the above, in the display device and the display panel of the present invention, different electrode groups have different pitches to generate electric fields of different sizes. In the display device, different sized electric fields generated by the different pitches are used to drive different light source groups to improve the transmittance and color shift of the display device.

為讓本發明之上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。 The above described features and advantages of the present invention will be more apparent from the following description.

第一實施例 First embodiment

圖1是依照本發明之一實施例之顯示裝置的立體示意圖。請參考圖1,顯示裝置100包括一顯示面板110以及一光源模組120。前述之顯示面板110包括一第一基板112、一第二基板114以及一顯示介質116。其中,第二基板114位於第一基板112的對向側,顯示介質116位於第一基板112以及第二基板114之間。光源模組120位於顯示面板110的一側。在本實施例中,是以光源模組120位在靠近第一基板112的那一側為例,但光源模組120也可以位在靠近第二基板114那一側。 1 is a perspective view of a display device in accordance with an embodiment of the present invention. Referring to FIG. 1 , the display device 100 includes a display panel 110 and a light source module 120 . The foregoing display panel 110 includes a first substrate 112, a second substrate 114, and a display medium 116. The second substrate 114 is located on the opposite side of the first substrate 112 , and the display medium 116 is located between the first substrate 112 and the second substrate 114 . The light source module 120 is located at one side of the display panel 110. In this embodiment, the light source module 120 is located on the side close to the first substrate 112, but the light source module 120 may also be located on the side close to the second substrate 114.

圖2A是圖1之第一基板112的局部上視圖。請同時參考圖1以及圖2A,第一基板112上具有彼此交替設置的多個第一電極112a以及多個第二電極112b,每一第一電極112a與相鄰的第二電極112b之間具有一第一間距d1。圖2B是圖1之第二基板114的局部上視圖。接著請同時參考圖1以及圖2B,第二基板114上具有彼此交替設置的多個第三電極114a以及多個第四電極114b,其中每一第三電極114a與相鄰的第四電極114b之間具有一第二間距d2,且第二間距d2與第一間距d1不相等。 2A is a partial top view of the first substrate 112 of FIG. 1. Referring to FIG. 1 and FIG. 2A simultaneously, the first substrate 112 has a plurality of first electrodes 112a and a plurality of second electrodes 112b disposed alternately with each other, and each of the first electrodes 112a and the adjacent second electrodes 112b has A first spacing d1. 2B is a partial top view of the second substrate 114 of FIG. 1. Referring to FIG. 1 and FIG. 2B simultaneously, the second substrate 114 has a plurality of third electrodes 114a and a plurality of fourth electrodes 114b arranged alternately with each other, wherein each of the third electrodes 114a and the adjacent fourth electrode 114b There is a second spacing d2 between the two, and the second spacing d2 is not equal to the first spacing d1.

請再參考圖1,前述的光源模組120包括一第一波長光源組122、一第二波長光源組124以及一第三波長光源組126。在顯示面板110呈現顯示畫面時,第一、第二以及第三波長光源組122、124以及126依序點亮。當光源模 組120之第一波長光源組122被點亮時,藉由第一基板112上之第一電極112a以及第二電極112b來驅動顯示介質116。當光源模組120之第二波長光源組124被點亮時,藉由第二基板114上之第三電極114a以及第四電極114b來驅動顯示介質116。 Referring to FIG. 1 , the light source module 120 includes a first wavelength source group 122 , a second wavelength source group 124 , and a third wavelength source group 126 . When the display panel 110 presents a display screen, the first, second, and third wavelength light source groups 122, 124, and 126 are sequentially illuminated. When the light source mode When the first wavelength source group 122 of the group 120 is illuminated, the display medium 116 is driven by the first electrode 112a and the second electrode 112b on the first substrate 112. When the second wavelength light source group 124 of the light source module 120 is illuminated, the display medium 116 is driven by the third electrode 114a and the fourth electrode 114b on the second substrate 114.

在第一電極112a與第二電極112b被施加電壓後,第一間距d1會影響第一電極112a與第二電極112b之間產生的電場大小。同理,第二間距d2會影響第三電極114a與第四電極114b之間產生的電場大小。在本實施例中,第一間距d1與第二間距d2不相等,意即第一電極112a與第二電極112b之間產生之電場大小會與第三電極114a與第四電極114b之間產生之電場大小不同。在本實施例中,利用不同大小的電場驅動不同波長光源組,以改善施加單一電壓時顯示裝置100產生穿透度降低的問題,並避免高電壓時產生的色偏情形。 After the voltage is applied to the first electrode 112a and the second electrode 112b, the first pitch d1 affects the magnitude of the electric field generated between the first electrode 112a and the second electrode 112b. Similarly, the second pitch d2 affects the magnitude of the electric field generated between the third electrode 114a and the fourth electrode 114b. In this embodiment, the first pitch d1 and the second pitch d2 are not equal, that is, the magnitude of the electric field generated between the first electrode 112a and the second electrode 112b is generated between the third electrode 114a and the fourth electrode 114b. The electric field is different in size. In the present embodiment, different wavelengths of the light source group are driven by electric fields of different sizes to improve the problem that the display device 100 produces a decrease in transmittance when a single voltage is applied, and to avoid a color shift condition generated at a high voltage.

圖3是圖1之顯示裝置的畫素電路示意圖。詳細來說,本實施例的第一電極112a與一電晶體T電性相接,第二電極112b與一共用電極線CL電性相接。電晶體T的一端與掃描線SL相接,另一端與資料線DL相接。在此,電晶體T可做為電壓資訊是否寫入第一電極112a的開關元件,且電晶體T的型式可以是底部閘極型薄膜電晶體或頂部閘極型薄膜電晶體。當電晶體T被開啟使電壓資訊寫入第一電極112a時,第一電極112a被施加一電壓,且其電壓值不同於共用電極線CL的電壓值,使得第一電極 112a與第二電極112b之間具有電壓差。此時,第一電極112a與第二電極112b之間產生一電場,以驅動顯示介質116。接著,當光源模組120中的第一波長光源組122被點亮時,第一基板112上的第一電極112a以及第二電極112b以前述的方式來驅動顯示介質116。 3 is a schematic diagram of a pixel circuit of the display device of FIG. 1. In detail, the first electrode 112a of the embodiment is electrically connected to a transistor T, and the second electrode 112b is electrically connected to a common electrode line CL. One end of the transistor T is connected to the scanning line SL, and the other end is connected to the data line DL. Here, the transistor T can be used as a switching element for writing voltage information to the first electrode 112a, and the type of the transistor T can be a bottom gate type thin film transistor or a top gate type thin film transistor. When the transistor T is turned on to write voltage information to the first electrode 112a, the first electrode 112a is applied with a voltage, and its voltage value is different from the voltage value of the common electrode line CL, so that the first electrode There is a voltage difference between 112a and the second electrode 112b. At this time, an electric field is generated between the first electrode 112a and the second electrode 112b to drive the display medium 116. Next, when the first wavelength light source group 122 in the light source module 120 is illuminated, the first electrode 112a and the second electrode 112b on the first substrate 112 drive the display medium 116 in the manner described above.

在本實施例中,第二基板114上的第三電極114a以及第四電極114b驅動顯示介質116的方式與第一電極112a以及第二電極112b相同。第三電極114a同樣與一電晶體電性相連,而第四電極114b與一共用電極線電性相接。當光源模組120中的第二波長光源組124被點亮時,第二基板114上的第三電極114a以及第四電極114b以前述的方式來驅動顯示介質116。 In the present embodiment, the third electrode 114a and the fourth electrode 114b on the second substrate 114 drive the display medium 116 in the same manner as the first electrode 112a and the second electrode 112b. The third electrode 114a is also electrically connected to a transistor, and the fourth electrode 114b is electrically connected to a common electrode line. When the second wavelength light source group 124 in the light source module 120 is illuminated, the third electrode 114a and the fourth electrode 114b on the second substrate 114 drive the display medium 116 in the manner described above.

在本實施例中,當第一波長光源組122被點亮時,藉由第一基板112上之第一電極112a以及第二電極112b來驅動顯示介質116。當光源模組120之第二波長光源組124被點亮時,藉由第二基板114上之第三電極114a以及第四電極114b來驅動顯示介質116。在第一波長光源組122以及第二波長光源組124被點亮後,接著當光源模組120之第三波長光源組126被點亮,可藉由第一基板112上之第一電極112a以及第二電極112b來驅動顯示介質116,或是藉由第二基板114上之第三電極114a以及第四電極114b來驅動顯示介質116。 In the present embodiment, when the first wavelength source group 122 is illuminated, the display medium 116 is driven by the first electrode 112a and the second electrode 112b on the first substrate 112. When the second wavelength light source group 124 of the light source module 120 is illuminated, the display medium 116 is driven by the third electrode 114a and the fourth electrode 114b on the second substrate 114. After the first wavelength source group 122 and the second wavelength source group 124 are illuminated, then the third wavelength source group 126 of the light source module 120 is illuminated by the first electrode 112a on the first substrate 112 and The second electrode 112b drives the display medium 116, or the display medium 116 is driven by the third electrode 114a and the fourth electrode 114b on the second substrate 114.

詳細而言,光源模組120的各個波長光源組122、124、126的波長大小並不相同。在此,第一波長光源組122的 波長大於第二波長光源組124的波長,且第二波長光源組124的波長大於第三波長光源組126的波長。舉例來說,第一波長光源組122發出的是紅光,第二波長光源組124發出的是綠光,第三波長光源組126發出的是藍光。也就是說,本實施例的顯示裝置100是採用色序法,將紅、綠、藍三色的影像在時間軸上快速切換以產生混色的效果,並且利用不同的電極間距d1、d2所產生不同大小的電場來驅動不同顏色的波長光源組122、124、126對應到的顯示介質116。 In detail, the wavelengths of the respective wavelength light source groups 122, 124, and 126 of the light source module 120 are not the same. Here, the first wavelength source group 122 The wavelength is greater than the wavelength of the second wavelength source set 124, and the wavelength of the second wavelength source set 124 is greater than the wavelength of the third wavelength source set 126. For example, the first wavelength source group 122 emits red light, the second wavelength source group 124 emits green light, and the third wavelength source group 126 emits blue light. That is to say, the display device 100 of the present embodiment uses the color sequential method to rapidly switch the images of the three colors of red, green, and blue on the time axis to produce the effect of color mixing, and is generated by using different electrode spacings d1 and d2. Different sized electric fields drive the display medium 116 to which the different wavelengths of light source groups 122, 124, 126 correspond.

此外,第一電極112a與相鄰的第二電極112b之間的第一間距d1是小於第三電極114a與相鄰的第四電極114b之間的第二間距d2。換言之,在本實施例中,是以兩電極112a、112b之間的間距較小的第一間距d1驅動波長最長的第一波長光源組122,以兩電極114a、114b之間的間距較大的第二間距d2驅動波長次之的第二波長光源組124。在本實施例中,第一間距d1與第二間距d2之間的差值大於等於0.2微米;另一實施例中,第一間距d1與第二間距d2差值大於等於0.5微米,且小於等於5微米;在較佳的實施例中,第一間距d1與第二間距d2的差值大於等於0.8微米,且小於等於1.5微米,例如第一間距d1與第二間距d2的差值約為1微米。 Further, the first pitch d1 between the first electrode 112a and the adjacent second electrode 112b is smaller than the second pitch d2 between the third electrode 114a and the adjacent fourth electrode 114b. In other words, in the present embodiment, the first wavelength source group 122 having the longest wavelength is driven by the first pitch d1 having a small pitch between the two electrodes 112a, 112b, so that the interval between the two electrodes 114a, 114b is large. The second pitch d2 drives the second wavelength source set 124 of the second wavelength.

第二實施例 Second embodiment

圖5是依照本發明之一實施例之顯示面板的立體示意圖。顯示面板200具有至少一第一畫素單元220、至少一第二畫素單元240以及至少一第三畫素單元260。在圖5中,是以顯示面板200包括一個第一畫素單元220、一個第二畫素單元240以及一個第三畫素單元260為例進行說明,但本發明並不限制第一畫素單元220、第二畫素單元240以及第三畫素單元260的數量。其中第一畫素單元 220、第二畫素單元240以及第三畫素單元260分別包括一第一基板222、一第二基板224、一彩色濾光層226以及一顯示介質228。 FIG. 5 is a perspective view of a display panel in accordance with an embodiment of the present invention. The display panel 200 has at least one first pixel unit 220, at least one second pixel unit 240, and at least one third pixel unit 260. In FIG. 5, the display panel 200 includes a first pixel unit 220, a second pixel unit 240, and a third pixel unit 260 as an example, but the present invention does not limit the first pixel unit. 220. The number of second pixel units 240 and third pixel units 260. First pixel unit The second pixel unit 240 and the third pixel unit 260 respectively include a first substrate 222, a second substrate 224, a color filter layer 226, and a display medium 228.

前述的第一基板222上具有彼此交替設置的多個第一電極222a以及多個第二電極222b,其中每一第一電極222a與相鄰的第二電極222b之間具有一等距間距d3。第二基板224位於第一基板222的對向側,而彩色濾光層226位於第一基板222或是第二基板224上。在本實施例中,是以彩色濾光層226位在第二基板224上為例,但彩色濾光層226也可以位在第一基板222上。 The first substrate 222 has a plurality of first electrodes 222a and a plurality of second electrodes 222b arranged alternately with each other, wherein each of the first electrodes 222a and the adjacent second electrodes 222b have an equidistant spacing d3. The second substrate 224 is located on the opposite side of the first substrate 222 , and the color filter layer 226 is located on the first substrate 222 or the second substrate 224 . In the embodiment, the color filter layer 226 is disposed on the second substrate 224, but the color filter layer 226 may also be located on the first substrate 222.

顯示介質228位於第一基板222以及第二基板224之間。其中,第一畫素單元220之第一電極222a與第二電極222b之間的等距間距d3與第二畫素單元240之第一電極222a與第二電極222b之間的等距間距d4不相等。 The display medium 228 is located between the first substrate 222 and the second substrate 224. The equidistant spacing d3 between the first electrode 222a and the second electrode 222b of the first pixel unit 220 and the equidistant spacing d4 between the first electrode 222a and the second electrode 222b of the second pixel unit 240 are not equal.

第一電極222a與第二電極222b之間的等距間距d3會影響兩電極222a以及222b之間的電場大小。由於等距間距d3與等距間距d4並不相等,所以當對應到第一畫素單元220與對應到第二畫素單元240的第一電極222a與第二電極222b分別被驅動時,兩者會產生大小不同的電場。在本實施例中,利用不同的電場驅動不同畫素單元220、240、260,可以改善施加單一電壓時顯示面板200產生穿透度降低的問題,並避免高電壓時產生的色偏情形。 The equidistant spacing d3 between the first electrode 222a and the second electrode 222b affects the magnitude of the electric field between the two electrodes 222a and 222b. Since the equidistant spacing d3 and the equidistant spacing d4 are not equal, when the first pixel 222a and the second electrode 222b corresponding to the first pixel unit 220 and the second pixel unit 240 are respectively driven, both An electric field of a different size is generated. In the present embodiment, by driving different pixel units 220, 240, and 260 with different electric fields, it is possible to improve the problem that the display panel 200 is reduced in transmittance when a single voltage is applied, and to avoid a color shift condition generated at a high voltage.

For example, when the transistor T is turned on to write voltage information to the first electrode 222a, the first electrode 222a is applied with a voltage, and its voltage value is different from the voltage value of the common electrode line CL, so that the first electrode 222a and There is a voltage difference between the second electrodes 222b. At this time, an electric field is generated between the first electrode 222a and the second electrode 222b to drive the display medium 228.

In other words, the equidistant spacing d3 between the first electrode 222a and the second electrode 222b corresponding to the red pixel unit 220a is smaller than the equidistant spacing d4 between the first electrode 222a and the second electrode 222b corresponding to the green pixel electrode. And the equidistant spacing d4 between the first electrode 222a and the second electrode 222b corresponding to the green pixel unit 240a is smaller than the equidistant spacing d5 between the first electrode 222a and the second electrode 222b of the blue pixel unit 260a . That is, the equidistant spacing d5 is greater than the equidistant spacing d4, and the equidistant spacing d4 is greater than the equidistant spacing d3.

承上述,等距間距d4與等距間距d5的關係並不限於此,在另一個未繪示的實施例裡,綠色畫素單元240a之第一電極222a與第二電極222b之間的等距間距d4是等於藍色畫素單元260a之第一電極222a與第二電極222b之間的等距間距d5。此外,第一畫素單元220(紅色畫素單元220a)之第一電極222a與第二電極222b之間的等距間距d3與第二畫素單元240(綠色畫素單元240a)之第一電極222a與第二電極222b之間的等距間距d4之間的差值大於等於0.2微米;另一實施例中,等距間距d3與等距間距d4之 間的差值大於等於0.5微米,且小於等於5微米;在較佳的實施例中,等距間距d3與等距間距d4之間的差值大於等於0.8微米,且小於等於1.5微米,例如等距間距d3與等距間距d4之間的差值約為1微米。 In the above, the relationship between the equidistant spacing d4 and the equidistant spacing d5 is not limited thereto. In another embodiment not shown, the equidistant between the first electrode 222a and the second electrode 222b of the green pixel unit 240a. The pitch d4 is equal to the equidistant spacing d5 between the first electrode 222a and the second electrode 222b of the blue pixel unit 260a. In addition, the equidistant spacing d3 between the first electrode 222a and the second electrode 222b of the first pixel unit 220 (red pixel unit 220a) and the first electrode of the second pixel unit 240 (green pixel unit 240a) The difference between the equidistant spacing d4 between the second electrode 222b and the second electrode 222b is greater than or equal to 0.2 micrometers; in another embodiment, the equidistant spacing d3 and the equidistant spacing d4 The difference between the two is greater than or equal to 0.5 micrometers and less than or equal to 5 micrometers; in a preferred embodiment, the difference between the equidistant spacing d3 and the equidistant spacing d4 is greater than or equal to 0.8 micrometers and less than or equal to 1.5 micrometers, for example, etc. The difference between the distance d3 and the equidistant distance d4 is about 1 micrometer.

請再參考圖5,在本實施例中,是以第一電極222a與第二電極222b的線寬w1相同為例,但第一電極222a與第二電極222b的線寬w1也可以不完全相同。舉例來說,可以部分的第一電極222a的線寬較寬,或著是部分的第二電極222b線寬較寬,熟習此項技藝者可對各電極線寬作出設計變更,以符合實際應用時的需求。 Referring to FIG. 5 again, in the embodiment, the line width w1 of the first electrode 222a and the second electrode 222b is the same, but the line width w1 of the first electrode 222a and the second electrode 222b may not be completely the same. .

圖7是圖5之顯示面板的局部剖面圖。如圖7中所繪示,第一電極222a與第二電極222b是交替設置在第一基板222上,且第一電極222a與第二電極222b是位在同一平面上。換言之,本實施例是以顯示面板為共平面切換(In-Plane Switching,IPS)式的顯示面板為例進行說明,當第一電極222a以及第二電極222b之間具有一橫向電場E3時,可驅動顯示介質228。 Figure 7 is a partial cross-sectional view of the display panel of Figure 5. As shown in FIG. 7, the first electrode 222a and the second electrode 222b are alternately disposed on the first substrate 222, and the first electrode 222a and the second electrode 222b are located on the same plane. In other words, in the embodiment, the display panel is an In-Plane Switching (IPS) type display panel. When the first electrode 222a and the second electrode 222b have a transverse electric field E3, The display medium 228 is driven.

此外,在本實施例中,顯示介質228在未被施予一電場時具有光學等向性(optically isotropic)。根據本實施例,上述之顯示介質228包括藍相液晶,其例如是聚合物穩定型藍相液晶(polymer-stabilized blue phase liquid crystals)或是聚合物穩定型等向相液晶(polymer-stabilized isotropic phase liquid crystals)等等。在本實施例中,顯示介質228是透過電場的形成而驅動,使顯示介質228在光學等向性 與光學異向性之間轉換,以使顯示介質228發揮光閥之作用。 Further, in the present embodiment, the display medium 228 is optically isotropic when it is not applied to an electric field.

Switching between optical anisotropy causes display medium 228 to function as a light valve.

圖8是圖1之顯示裝置的驅動電壓-穿透率曲線圖(V-T curves)。請參考圖8,圖8中的曲線A、曲線B、曲線C分別是第一波長光源組122、第二波長光源組124、第三波長光源組126被點亮時,以相同電極間距驅動顯示介質的驅動電壓與穿透率的關係曲線。由圖8的曲線圖可看出,以相同電極間距驅動顯示介質時,曲線A明顯的偏移曲線B以及曲線C。且若在相同的穿透率下,曲線A的驅動電壓明顯高於曲線B以及曲線C。 Figure 8 is a graph showing driving voltage-transmission curves (V-T curves) of the display device of Figure 1. Please refer to FIG. 8. Curves A, B, and C in FIG. 8 are driven by the same electrode spacing when the first wavelength source group 122, the second wavelength source group 124, and the third wavelength source group 126 are illuminated, respectively. The relationship between the driving voltage of the medium and the transmittance. As can be seen from the graph of Fig. 8, when the display medium is driven at the same electrode pitch, the curve A is significantly offset from the curve B and the curve C. And at the same transmittance, the driving voltage of curve A is significantly higher than curve B and curve C.

接著請參考曲線D,曲線D是第一波長光源組122被點亮時,改以較小之電極間距的電極驅動顯示介質的驅動電壓與穿透率的關係曲線。將曲線A與曲線D做比較,可看出當改以電極間距較小的電極驅動顯示介質時,曲線D會與曲線B以及曲線C較一致。因此,由圖8中的曲線A與曲線D的比較可理解,採用不同的電極間距改變電極的電場強度,可有效的調整驅動電壓與穿透率的關係,並可增加穿透率,避免在高驅動電壓時產生色偏問題。 Next, please refer to the curve D. The curve D is a relationship between the driving voltage and the transmittance of the electrode driving display medium which is changed to the electrode spacing of the first wavelength when the first wavelength source group 122 is lit. Comparing the curve A with the curve D, it can be seen that when the display medium is driven by the electrode with a smaller electrode spacing, the curve D will be more consistent with the curve B and the curve C. Therefore, it can be understood from the comparison of the curve A and the curve D in FIG. 8 that changing the electric field intensity of the electrode by using different electrode spacings can effectively adjust the relationship between the driving voltage and the transmittance, and can increase the transmittance and avoid A color shift problem occurs at high driving voltages.

承上所述,在圖1的實施例中,是第一電極112a以及第二電極112b來驅動第一波長光源組122,並利用第三電極114a以及第四電極114b來驅動第二光源波長組124。由於第一電極112a以及第二電極112b之間的第一間距d1小於第三電極114a以及第四電極114b之間的第二間距d2,所以可以藉此來改善以及調整在高驅動電壓時色偏 的情況。 As described above, in the embodiment of FIG. 1, the first electrode 112a and the second electrode 112b drive the first wavelength source group 122, and the third electrode 114a and the fourth electrode 114b are used to drive the second source wavelength group. 124. Since the first pitch d1 between the first electrode 112a and the second electrode 112b is smaller than the second pitch d2 between the third electrode 114a and the fourth electrode 114b, the color shift at a high driving voltage can be improved and adjusted thereby.
