值得說明的是，一般所謂將紅光、綠光、藍光三色(亦即R、G、B三原色)膽固醇液晶混合成為白光，該”白光”實際為透明光，而本發明所加入之該白光膽固醇液晶37W，該”白光”指的是膽固醇液晶與高分子單體(monomer)加上光啟始劑，藉著與顯示區域中殘留之產生聚合反應形成dispersed polymer，由導入multi-domain的planar texture並調整膽固醇液晶的螺距近紅光，因domain和domain的螺旋軸傾斜方向不同而反射的波長也不同，全部的波長疊加之後，所呈現的”白色”；本發明之控制方式為，當欲顯示紅光反射時，只要控制該綠光膽固醇液晶37G、藍光膽固醇液晶37B顯示為焦點圓錐狀態(focal conic state)，控制該白光膽固醇液晶37W顯示為平面狀態(planar state)，即可提高該紅光膽固醇液晶37R之紅光反射率，顯示綠光及藍光反射之原理相同，而若是控制該紅光膽固醇液晶37R、綠光膽固醇液晶37G、藍光膽固醇液晶37B、白光膽固醇液晶37W均為平面狀態(planar state)時，則可提高白光反射率。It should be noted that, generally, the three colors of red, green, and blue light (that is, the three primary colors of R, G, and B) are mixed into white light, and the "white light" is actually transparent light, and the white light added by the present invention. Cholesteric liquid crystal 37W, the "white light" refers to a cholesteric liquid crystal and a polymer monomer plus a photoinitiator, which forms a dispersed polymer by polymerization with a residual in the display region, and is introduced into a multi-domain planar. Texture and adjust the pitch of the cholesteric liquid crystal near red light, because the wavelength of the spiral axis of the domain and domain is different, and the reflected wavelength is different. After all the wavelengths are superimposed, the "white" is presented; the control method of the present invention is when When the red light reflection is displayed, the green light cholesterol liquid crystal 37G and the blue light cholesterol liquid crystal 37B are controlled to be in a focal conic state, and the white light cholesterol liquid crystal 37W is controlled to be in a planar state, thereby improving the red color. The red light reflectance of the light cholesterol liquid crystal 37R shows the same principle of green light and blue light reflection, and if the red light cholesterol liquid crystal 37R, green is controlled A cholesteric liquid crystal 37G, blue cholesteric liquid crystal 37B, 37W white cholesteric liquid crystal are both planar state (planar state), the reflectance of white light can be increased.
關於本發明所採用之白光膽固醇液晶之製備方式為，將白光膽固醇液晶之反射波長調整為近紅外光，加入高分子單體，可形成多象限(multi-domain)之平面狀態(planar state)，由於象限(domain)與象限之螺旋軸傾斜方向不同而反射之波長也不同(依公式λ=npcos θ計算，其中，λ為液晶反射波長，n為液晶折射率，p為液晶螺距，θ為入射光與平面的夾角)，因此在全部波長疊加之後可呈現白光 反射，而在焦點圓錐狀態(focal conic state)呈現散射(scattering)黑色。本發明所提供之膽固醇液晶顯示器結構，其隔牆結構除了第三圖及第四圖所示該第一實施例之單行單層形式之隔牆結構34外，亦可做其他變化，請參閱第五圖所示該第二實施例之俯視結構圖，該膽固醇液晶顯示器40之隔牆結構44為單層結構，該隔牆結構44具有四個空間441~444，該四個空間441~444係2X2陣列於同一平面上，於該四個空間441~444內分別設置有紅光膽固醇液晶47R、綠光膽固醇液晶47G、藍光膽固醇液晶47B、白光膽固醇液晶47W；請參閱第六圖所示該第三實施例之俯視結構圖，該膽固醇液晶顯示器50之隔牆結構54仍是單層結構，該隔牆結構54具有八個空間541~548，該八個空間541~548係2X4陣列，亦即具有二行，每一行具有四個空間，於每行的四個空間內分別設置有紅光膽固醇液晶57R、綠光膽固醇液晶57G、藍光膽固醇液晶57B、白光膽固醇液晶57W，且兩行之紅光膽固醇液晶57R、綠光膽固醇液晶57G、藍光膽固醇液晶57B、白光膽固醇液晶57W相互錯位；第五圖及第六圖兩實施例控制光反射之方式與第三圖及第四圖該實施例相同，該第五圖及第六圖係用以說明本發明之隔牆結構可設置為單層，而隔牆結構所形成之用以容置膽固醇液晶之空間，可為單行排列或複數行列陣列。The white light cholesteric liquid crystal used in the present invention is prepared by adjusting the reflection wavelength of the white cholesteric liquid crystal to near-infrared light, and adding a polymer monomer to form a multi-domain planar state. Since the wavelength of the quadrant and the quadrant of the quadrant are different, the wavelength of the reflection is different (calculated according to the formula λ=npcos θ, where λ is the liquid crystal reflection wavelength, n is the liquid crystal refractive index, p is the liquid crystal pitch, and θ is the incident Light and plane angle), so white light can be presented after all wavelengths are superimposed Reflection, while scattering black in the focal conic state. The structure of the cholesteric liquid crystal display provided by the present invention, in addition to the partition wall structure 34 of the single-layer single-layer form of the first embodiment shown in the third and fourth figures, can also be changed.
