Description
本發明是有關於一種光電裝置,且特別是有關於一種顯示裝置。The present invention relates to an optoelectronic device, and in particular to a display device.
膽固醇液晶顯示器(Cholesteric Liquid Crystal Display,CLCD)是一種呈螺旋狀排列的特殊液晶模式,通過在向列型液晶中加入旋光劑來達到特殊排列結構,並利用膽固醇液晶分子在不同電位下反射與透過兩種不同偏極光旋轉狀態來達到顯示效果。一般而言,為維持膽固醇液晶顯示器的間隙(cell gap),膽固醇液晶顯示器中設有間隙物(spacer)。然而,間隙物的設置使得配向液容易累積在間隙物附近,造成間隙物附近的配向膜膜厚過厚。在配向膜膜厚過厚的區域中,膽固醇液晶分子不易感受到電場的驅動,進而影響顯示效果。Cholesteric Liquid Crystal Display (CLCD) is a special liquid crystal mode arranged in a spiral shape. It achieves a special arrangement structure by adding an optical active agent to the nematic liquid crystal, and uses cholesterol liquid crystal molecules to reflect and transmit at different potentials. Two different polarized light rotation states are used to achieve the display effect. Generally speaking, in order to maintain the cell gap of the cholesteric liquid crystal display, a spacer is provided in the cholesteric liquid crystal display. However, the arrangement of the spacer makes it easy for the alignment liquid to accumulate near the spacer, causing the alignment film near the spacer to be too thick. In areas where the alignment film is too thick, the cholesterol liquid crystal molecules are not easily driven by the electric field, thus affecting the display effect.

圖4之比較例的光電元件10’與圖5、圖6及圖7的實施例的光電元件10A、10B、10的差異在於: 圖4之比較例的光電元件10’不包括實施例的光電元件10A、10B、10的第三電極240。圖5、圖6及圖7之各實施例的光電元件10A、10B、10的差異在於: 圖5的第三電極240的寬度W240-1小於間隙物PS的寬度WPS-1,圖6的第三電極240的寬度W240-1等於間隙物PS的寬度WPS-1,而圖7的第三電極240的寬度W240-1大於間隙物PS的寬度WPS-1。比較各實施例的圖5、圖6及圖7與比較例的圖4可知,相較於圖4的比較例,無論第三電極240的寬度W240-1小於、等於或大於間隙物PS的寬度WPS-1,圖5、圖6及圖7之各實施例的第三電極240都能提升光電元件10A、10B、10在區域II(即,配向膜PI2累積區)的亮度。如圖6及圖7所示,特別是,當第三電極240的寬度W240-1大於或等於間隙物PS的寬度WPS-1時,第三電極240提升區域II之亮度的效果更為顯著。The difference between the optoelectronic element 10' of the comparative example in Figure 4 and the optoelectronic elements 10A, 10B, and 10 of the embodiments of Figures 5, 6, and 7 is that: the optoelectronic element 10' of the comparative example of Figure 4 does not include the optoelectronic elements of the embodiment. The third electrode 240 of the elements 10A, 10B, 10. The difference between the optoelectronic components 10A, 10B, and 10 in the embodiments of FIG. 5, FIG. 6, and FIG. 7 is that: the width W240-1 of the third electrode 240 in FIG. 5 is smaller than the width WPS-1 of the spacer PS, and the width W240-1 of the third electrode 240 in FIG. 6 The width W240-1 of the third electrode 240 is equal to the width WPS-1 of the spacer PS, and the width W240-1 of the third electrode 240 in FIG. 7 is greater than the width WPS-1 of the spacer PS. Comparing Figures 5, 6 and 7 of each embodiment with Figure 4 of the comparative example, it can be seen that compared to the comparative example of Figure 4, no matter the width W240-1 of the third electrode 240 is less than, equal to or greater than the width of the spacer PS WPS-1, the third electrode 240 in each embodiment of FIG. 5, FIG. 6 and FIG. 7 can improve the brightness of the photovoltaic elements 10A, 10B, and 10 in area II (ie, the alignment film PI2 accumulation area). As shown in FIGS. 6 and 7 , especially when the width W240 - 1 of the third electrode 240 is greater than or equal to the width WPS - 1 of the spacer PS, the effect of the third electrode 240 on improving the brightness of the region II is more significant.

舉例而言,在本實施例中,當光電元件10操作於全亮畫面時,第二電極230與第一電極120具有電位差V2,第三電極240與第一電極120具有電位差V3,且V2、V3滿足下式:0.8≦(V3/V2)≦1。此時,第三電極240提升區域II之亮度的效果較佳,以下配合圖8至圖12說明之。For example, in this embodiment, when the photoelectric element 10 operates in a fully bright screen, the second electrode 230 and the first electrode 120 have a potential difference V2, the third electrode 240 and the first electrode 120 have a potential difference V3, and V2, V3 satisfies the following formula: 0.8≦(V3/V2)≦1.
