Description
本發明是有關於一種顯示面板及顯示面板裝飾框之製造方法與其應用，且特別是有關於一種顯示面板之可見光全波段均勻反射性散射之裝飾框及其製造方法，與應用顯示面板之觸控顯示系統。 The invention relates to a manufacturing method of a display panel and a decorative frame of a display panel and an application thereof, and particularly relates to a decorative frame of a visible light full-band uniform reflective scattering of a display panel and a manufacturing method thereof, and a touch panel of the application display panel display system.
現今消費者對於3C產品不止要求內在的品質也注重外觀的質感。3C產品外觀的裝飾膜除了能遮蔽內部雜亂的電子元件，更可為覆蓋用的透明基板作為邊框裝飾，不但賦予產品細膩美麗的外觀，也提升了產品的價值感，為產品帶來嶄新的生命。 Today's consumers are not only demanding the inherent quality of 3C products, but also paying attention to the appearance of the texture. In addition to shielding the internal messy electronic components, the decorative film of the 3C product can also be used as a frame for the transparent substrate for covering, which not only gives the product a delicate and beautiful appearance, but also enhances the sense of value of the product and brings a new life to the product. .
目前許多3C產品所使用的白色裝飾膜，如第1圖所示，一般是利用濕式製程，如網印、噴塗、旋轉塗佈等方式，在一透明基板S上塗佈一層白色塗料P，如白色油墨、白色色阻或白色光阻，以作為面外之產品邊框。當外部光線通過透明基板S到達白色塗料P，白色塗料P反射光線呈色。 At present, many white decorative films used in 3C products, as shown in Fig. 1, are generally coated with a white coating P on a transparent substrate S by a wet process such as screen printing, spraying, spin coating, or the like. Such as white ink, white color resist or white photoresist, as a product border. When the external light passes through the transparent substrate S to reach the white paint P, the white paint P reflects the light to a color.
然而，塗佈的膜層厚度若不足則遮蔽性不佳。為達到足夠的遮蔽性(即高光密度O.D.值)及白色飽和度，則膜厚需達到數十um以上，但膜厚過厚容易造成後續膜層堆疊之難度及須考量的因素增加，且所需成本相對提升。再者以傳統濕式製程的方式堆疊膜層，容易產生膜厚不均，特 別是大面積時均勻性不佳的問題更是明顯。 However, if the thickness of the applied film layer is insufficient, the shielding property is not good. In order to achieve sufficient shielding (ie, high optical density OD value) and white saturation, the film thickness needs to be several tens of um or more, but the film thickness is too thick, which may cause difficulty in stacking subsequent layers and factors to be considered, and The cost of ownership is relatively high. Furthermore, the film layer is stacked in a conventional wet process, which is prone to uneven film thickness. The problem of poor uniformity over a large area is even more obvious.
再者，白色塗料P的油墨或色阻均利用有機溶劑混合化學色料而成，製程後的廢料、廢液對環境是一大危害且回收不易，需考量後續廢料廢液如何做好回收處理其可能衍生之環保議題。也因白色塗料P多為有機材料組成，對溫度及酸鹼性較為敏感易受影響，易使白色塗料產生黃化裂化等現象，後續製程選擇性將受限制。 Furthermore, the ink or color resistance of the white paint P is formed by mixing the chemical colorant with the organic solvent, and the waste and waste liquid after the process are a great hazard to the environment and difficult to recycle, and it is necessary to consider how the waste waste liquid is recycled after treatment. It may be derived from environmental issues. Because white paint P is mostly composed of organic materials, it is sensitive to temperature and acidity and alkalinity, and it is easy to cause yellowing cracking of white paint, and the selectivity of subsequent processes will be limited.

The roughness can be controlled by coating the residence time of the smear or soaking the acid and alkali time and adjusting the etchant composition (eg, concentration, ratio, etc.). The substrate 40 is then cleaned. The roughness of the rough surface is at least greater than 1 μm. In one embodiment, the roughness (R a , center line average roughness) of the surface of the substrate 40 is between 1 μm and 20 μm. A material having a reflectance of 50% or more, such as an aluminum film (Al) or a silver film (Ag), may be formed on the first surface 401 having a rough surface of the substrate 40 or formed on the rough surface. The second surface 402 serves as a reflective layer.
第6圖係為本發明實施例之裝飾膜組件的一種形成具有粗糙面基板之示意圖。此方法係在一基板51(例如透明基板)之一側形成一具有高霧度(haze)值的材料，如噴塗上一層防眩膜(anti-glare film)52，AG材料裡面含有奈米微 粒，可使基板51表面霧度提升，而形成具有粗糙面(即防眩膜52)之基板50，以提供顯示面板本體之具有粗糙面的第一表面。實施例中，防眩膜52係具有一霧度值50%~100%，以提供粗糙面之粗糙度(Rpv，全粗糙高度)至少大於1μm。高反射率金屬膜如鋁膜(Al)、銀膜(Ag)等反射率大於等於50%的材料，可形成於基板51之一側，以作為反射層。 Fig. 6 is a schematic view showing the formation of a substrate having a rough surface of the decorative film assembly of the embodiment of the present invention. The method forms a material having a high haze value on one side of a substrate 51 (for example, a transparent substrate), such as spraying an anti-glare film 52, and the AG material contains nano particles. The surface haze of the substrate 51 can be increased to form a substrate 50 having a rough surface (i.e., the anti-glare film 52) to provide a first surface having a rough surface of the display panel body. In the embodiment, the anti-glare film 52 has a haze value of 50% to 100% to provide a rough surface roughness (R pv , full roughness height) of at least greater than 1 μm. A material having a high reflectance metal film such as an aluminum film (Al) or a silver film (Ag) having a reflectance of 50% or more may be formed on one side of the substrate 51 as a reflective layer.
第7A~7C圖為本發明實施例具防眩膜之裝飾膜組件的三種結構設置之示意圖。 7A to 7C are schematic views showing three structural arrangements of a decorative film assembly with an anti-glare film according to an embodiment of the present invention.
如第7A圖所示，可於基板51之一側鍍上反射層64a，如高反射率金屬膜如鋁膜(Al)、銀膜(Ag)等反射率大於等於50%的材料，再噴塗防眩膜52於反射層64a上。此時反射層64a係位於基板51和防眩膜52之間。 As shown in FIG. 7A, a reflective layer 64a may be plated on one side of the substrate 51, such as a high reflectivity metal film such as an aluminum film (Al), a silver film (Ag), or the like having a reflectance of 50% or more, and then sprayed. The anti-glare film 52 is on the reflective layer 64a. At this time, the reflective layer 64a is located between the substrate 51 and the anti-glare film 52.
如第7B圖所示，亦可於基板51之一側噴塗防眩膜52，於基板51相對之另一側鍍上反射層64b。此時反射層64b和防眩膜52係分別位於基板51異側之表面。 As shown in FIG. 7B, the anti-glare film 52 may be sprayed on one side of the substrate 51, and the reflective layer 64b may be plated on the other side of the substrate 51. At this time, the reflective layer 64b and the anti-glare film 52 are respectively located on the surface on the opposite side of the substrate 51.
如第7C圖所示，亦可於基板51之一側噴塗防眩膜52，再於防眩膜52上形成反射層64c。此時反射層64c和防眩膜52係位於基板51之同一側。 As shown in FIG. 7C, the anti-glare film 52 may be sprayed on one side of the substrate 51, and the reflective layer 64c may be formed on the anti-glare film 52. At this time, the reflective layer 64c and the anti-glare film 52 are located on the same side of the substrate 51.
依照上述製程所製作之裝飾膜組件，利用光入射高反射率之反射層再於粗糙面產生光線漫射現象，可得到近白色裝飾性鍍膜，以作為顯示面板裝飾框。若以乾式製程製備，實施例之白色鍍膜膜厚約100nm左右即可達到高遮蔽性(高O.D.值，O.D.value>4)，且後續膜層堆疊不均及斷線 等問題較少。相較於傳統使用白色油墨或塗料，實施例不但有效減少薄膜厚度，更提升膜厚均勻性及後續製程的方便性。 According to the decorative film assembly produced by the above process, a light-reflecting layer having a high reflectivity is incident on the rough surface to generate a light-diffusing phenomenon, and a near-white decorative coating can be obtained as a decorative frame of the display panel. If prepared by a dry process, the white coating film of the embodiment has a thickness of about 100 nm to achieve high shielding (high O.D. value, O.D. value>4), and subsequent film layer stacking is uneven and broken. There are fewer issues. Compared with the conventional use of white ink or paint, the embodiment not only effectively reduces the film thickness, but also improves the film thickness uniformity and the convenience of subsequent processes.

Wherein the roughness of the first surface having the rough surface is at least greater than 1 μm, and the reflective layer may be located on one of the rough surface or the non-rough surface, and the reflective layer is correspondingly located at the non-penetrating region 114, and the reflection thereof The rate is greater than or equal to 50%. The display panel can thereby be substantially white in the non-penetration zone 114.
再者，顯示面板本體11的具粗糙面之第一表面例如是直接以機械或化學方式對基板表面進行處理，或是以在基板上鍍上防眩膜。請同時參照第7A-7C圖和第2圖。以實施例之具有防眩膜之裝飾膜組件為例，如第7A-7C圖所示，反射層64a-64c係位於基板51之一側且對應非穿透區114；而防眩膜52係位於反射層64a上(第7A圖)、或位於 基板51之異於反射層之另一表面上(如第7B圖的反射層64b)或位於反射層(如第7C圖的反射層64c)與基板51之間。防眩膜52例如是對應非穿透區114並環設於穿透區112之周邊。反射層之反射率大於等於50%，防眩膜之粗糙度至少大於1μm；藉此，顯示面板10於非穿透區114大致係呈白色。實際應用時，防眩膜52例如是環設於顯示面板本體11的穿透區112之周邊(第2圖)。 Furthermore, the first surface of the display panel body 11 having a rough surface is, for example, directly or mechanically or chemically treating the surface of the substrate, or is coated with an anti-glare film on the substrate.

以下係提出一些相關實驗和結果，以說明實施例之裝飾膜組件的物理性質。 Some related experiments and results are presented below to illustrate the physical properties of the decorative film assembly of the examples.
此實驗中所提出之實施例裝飾膜組件係以研磨方式使基板表面粗糙化，並在粗糙面上並鍍上反射膜，如第3B圖所示之結構(粗糙面與反射膜同側)。表1係為傳統白色光阻、金屬鋁鍍膜、及實施例之裝飾膜組件所呈現的白色鍍膜在SCI及SCE測量模式下的Lab色彩空間-包括顏色維度L*(代表亮度)，和顏色對立維度a*，b*。 The decorative film assembly of the embodiment proposed in this experiment roughened the surface of the substrate by grinding, and was coated with a reflective film on the rough surface, as shown in Fig. 3B (rough surface is on the same side as the reflective film). Table 1 shows the Lab color space of the white coating exhibited by the conventional white photoresist, the metal aluminum coating, and the decorative film assembly of the embodiment in the SCI and SCE measurement modes - including the color dimension L* (representing brightness), and the color opposition Dimensions a*, b*.
物體顏色會隨著觀察條件，檢查角度及照明角度不同而變化。即使物體由相同材質構成，但由於表面光澤度的不同，也會使顏色看起來有所變化。鏡面反射光和漫射光的含量是根據物體表面情況而定的，但在材料和顏色一定的條件下，兩種光的總量總是一樣的。排除鏡面反射光的測量顏色的方法稱之為SCE(Specular Component Excluded)。包含鏡面反射光的測量顏色的方法稱之為SCI(Specular Component Included)。在SCE測量模式中，鏡面反射光被排除在外面只測漫射光，所測出的值與觀測者看上去的物體顏色是相當的。當使用SCI模式時，測量過程中鏡面反射光與漫射光會被一起包含進去，所測得的值是物體整體客觀顏色，而與物體表面條件無關。 The color of the object will vary depending on the viewing conditions, inspection angle and illumination angle. Even if the object is made of the same material, the color will look different due to the difference in surface gloss. The amount of specularly reflected light and diffused light is determined according to the surface condition of the object, but the total amount of the two kinds of light is always the same under certain conditions of material and color. The method of excluding the measured color of specularly reflected light is called SCE (Specular Component) Excluded). The method of measuring the color including specularly reflected light is called SCI (Specular Component Included). In the SCE measurement mode, the specularly reflected light is excluded from the outside and only the diffused light is measured, and the measured value is equivalent to the color of the object that the observer looks like. When the SCI mode is used, the specular reflected light and the diffused light are included together during the measurement, and the measured value is the overall objective color of the object, regardless of the surface condition of the object.
從表1之結果可看出：傳統白色光阻在包含鏡面反射光方式(SCI)與不包含鏡面反射光方式(SCE)的測量模式中亮度值(L*)很接近。金屬鋁鍍膜(高反射率材質，鏡面反射值高)不包含鏡面反射光方式(SCE)的測量結果接近0。而實施例之裝飾膜組件所呈現的白色鍍膜在SCI及SCE測量模式下的亮度值(維度L*)也十分接近，人眼可判斷為白色材料，其顏色維度之a*、b*值也很接近白色的0、0。 It can be seen from the results of Table 1 that the conventional white photoresist is close to the luminance value (L*) in the measurement mode including the specular reflection mode (SCI) and the specular reflection mode (SCE). Metallic aluminum coatings (high reflectivity materials, high specular reflection values) do not include specularly reflected light (SCE) measurements close to zero. The white coating film of the decorative film assembly of the embodiment has a brightness value (dimension L*) in the SCI and SCE measurement modes, and the human eye can be judged as a white material, and the a* and b* values of the color dimension are also Very close to the white 0, 0.
以一透明玻璃作為實施例之基板，進行表面粗糙化處理後，搭配高反射率金屬材料如鋁(Al，反射率約50%)。請參照附圖一，有玻璃基板表面進行粗糙化處理與未進行粗糙化處理，及之後分別鍍上高反射率金屬鋁之圖示。附圖中可清楚看出，有表面粗糙化處理之玻璃基板搭配上高反射率金屬材料鋁，目視效果可達到白色呈現。實驗中亦使用其他種金屬如使用鉻(Cr)或鈦(Ti)金屬(反射率約45%)進行測試，目測其顏色係呈現淺灰色(可能因反射率過低使得漫射光亮度不足，所以呈現灰色)。 A transparent glass was used as the substrate of the example, and after surface roughening treatment, a high-reflectivity metal material such as aluminum (Al, reflectance of about 50%) was used. Referring to FIG. 1, the surface of the glass substrate is roughened and not roughened, and then plated with high reflectivity metal aluminum. As is clear from the drawings, the glass substrate having the surface roughening treatment is matched with the aluminum material having high reflectivity, and the visual effect can be achieved in white. Other metals such as chromium (Cr) or titanium (Ti) metal (reflectance of about 45%) were also used in the experiment, and the color was visually observed to be light gray (possibly because the reflectance is too low, the diffused light is insufficient in brightness, so Rendered in gray).
表2係簡列實施例之裝飾膜組件，其粗糙化基板之粗糙度Rpv(全粗糙高度，即最高點與最低點差值)在3.41μm~8.3μm時，所呈現的白色鍍膜在SCI及SCE測量模式下的平均亮度值(L*)和顏色(a*、b*)值。 Table 2 is a decorative film assembly of the embodiment, which roughens the roughness R pv of the substrate (the full roughness height, that is, the difference between the highest point and the lowest point) at 3.41 μm to 8.3 μm, and the white coating is presented in SCI. And the average brightness value (L*) and color (a*, b*) values in the SCE measurement mode.
此實驗中係分別製作具三種不同霧度值(Haze)-60%、15%和1%的AG樣品，即透明基板上噴塗一層防眩膜使基板表面霧度提升，以形成具有粗糙面之基板(以作為顯示面板本體11的具粗糙面之第一表面)，在基板的另一面則鍍上反射層鋁(結構請參照第7B圖)。表3係為該些鍍膜樣品在SCI及SCE測量模式下的Lab色彩空間-包括顏色維度L*(代表亮度)和顏色對立維度a*，b*，以及粗糙度(Rz)。而目視該些樣品顏色發現，當樣品表面粗糙度大於1μm時，人眼判斷為白色。 In this experiment, AG samples with three different haze values (Haze)-60%, 15% and 1% were prepared, that is, an anti-glare film was sprayed on the transparent substrate to increase the haze of the substrate surface to form a rough surface. The substrate (the first surface having a rough surface as the display panel body 11) is plated with a reflective layer aluminum on the other surface of the substrate (see FIG. 7B for the structure). Table 3 shows the Lab color space of the coated samples in the SCI and SCE measurement modes - including the color dimension L* (representing brightness) and the color opposite dimensions a*, b*, and roughness (Rz). The color of the samples was visually observed, and when the surface roughness of the sample was more than 1 μm, the human eye judged to be white.
