Abstract
Description
本發明係關於一種顯示裝置，特別是一種提高色彩飽和度的顯示裝置。The invention relates to a display device, in particular to a display device with improved color saturation.
目前 TFT-LCD 面板彩色濾光片中，是以含金屬的感光顏料作為色彩顯示的材料。在色彩及光學的表現上，由於其放射頻譜太寬，目前的CF 其演色性差，色純度較低 ; 雖增加膜厚可以提高其色彩飽和度，但同時會降低面板整體的穿透率。Currently, TFT-LCD panel color filters use metal-containing photosensitive pigments as materials for color display. In terms of color and optical performance, due to its wide emission spectrum, the current CF has poor color rendering and low color purity; although increasing the film thickness can increase its color saturation, it will also reduce the overall transmittance of the panel.
量子點(Quantum Dot)是一種光致發光材料，可吸收背光源後會再發光，具有等於或小於約10奈米(nm)之直徑之奈米晶體(nano crystal)，是半導體材料組成，相較於傳統的感光顏料，量子點在較窄之波長帶產生更密集的光且具有高穩定性。由於量子點具有轉換波長的功能，故可將量子點放在濾光片中，取代原來的色阻。因此，如何使用量子點搭配背光源的選用，以達到廣色域和提高穿透率，實為此技術領域者所關注的重點之一。Quantum Dot is a photoluminescence material that absorbs backlight and then emits light. It has a nano crystal with a diameter equal to or less than about 10 nanometers (nm). It is a semiconductor material. Compared with traditional photosensitive pigments, quantum dots produce more dense light in a narrower wavelength band and have high stability. Because the quantum dots have the function of wavelength conversion, the quantum dots can be placed in a filter to replace the original color resistance. Therefore, how to use quantum dots with the choice of backlight to achieve a wide color gamut and increase the transmittance is really one of the focuses of those skilled in the art.
本發明所揭露的一種顯示裝置，包含顯示面板、背光模組及控制模組。背光模組設置於該顯示面板的一側或背側，用以提供顯示面板顯示時所需的背光，該背光模組包含第一光源和第二光源，第一光源在一圖框期間之第一時段所產生之光線在波長320nm至波長420nm具有一波峰，第二光源在該圖框期間之第二時段所產生之光線在波長420nm至波長480nm具有一波峰，控制模組用以控制該第一光源於第一時段開啟，控制該第二光源於第二時段開啟。A display device disclosed in the present invention includes a display panel, a backlight module, and a control module. The backlight module is disposed on one side or the back side of the display panel, and is used to provide a backlight required for display panel display. The backlight module includes a first light source and a second light source. The light generated in a period has a peak at a wavelength of 320nm to 420nm, and the light generated by the second light source in a second period of the frame period has a peak at a wavelength of 420nm to 480nm. The control module is used to control the first A light source is turned on in the first period, and the second light source is controlled to be turned on in the second period.
綜上所述，利用控制第一光源(UV光源)與第二光源(藍光源)交替開關，從而控制顯示裝置之穿透效率與色彩飽和度，改善利用單一UV光源使液晶劣化或單一藍色LED光源造成漏藍光使色彩飽和度下降的問題。In summary, the first light source (UV light source) and the second light source (blue light source) are switched on and off alternately to control the penetration efficiency and color saturation of the display device, and improve the use of a single UV light source to degrade the liquid crystal or a single blue LED light sources cause the problem of leaking blue light and reducing color saturation.

圖1為本發明顯示裝置100之一實施例示意圖。如圖1所示，顯示裝置100包含顯示面板10和背光模組20，於本實施例中，背光模組20設置於顯示面板10之背側(如圖1所示之直下式背光) ，但本發明不以此為限，背光模組20亦可設置於顯示面板10之一側(例如為側入式背光)。顯示面板10包含一第一基板110、一薄膜電晶體層120、一顯示介質130、一彩色濾光層140以及一第二基板150。於本實施例中，背光模組20包含一可產生紫外光線的UV光源，一般而言，UV光源所產生之光線頻譜在波長320nm至波長420nm具有一波峰。彩色濾光層140包含第一波長轉換層140a、第二波長轉換層140b以及第三波長轉換層140c。第一波長轉換層140a包含有紅色量子點材料，用來吸收紫外光線以激發出紅色光，第二波長轉換層140b包含有綠色量子點材料，用來吸收紫外光線以激發出綠色光，第三波長轉換層140c包含有藍色量子點材料，用來吸收紫外光線以激發出藍色光。顯示介質130具有調節光通量之特性，例如為液晶分子。本實施例利用紫外光線激發量子點材料具有高光穿透效率及高色彩飽和度之優勢。FIG. 1 is a schematic diagram of an embodiment of a display device 100 according to the present invention. As shown in FIG. 1, the display device 100 includes a display panel 10 and a backlight module 20. In this embodiment, the backlight module 20 is disposed on the back side of the display panel 10 (a direct-type backlight shown in FIG. 1), but The present invention is not limited thereto, and the backlight module 20 may also be disposed on one side of the display panel 10 (for example, an edge-type backlight). The display panel 10 includes a first substrate 110, a thin film transistor layer 120, a display medium 130, a color filter layer 140, and a second substrate 150. In this embodiment, the backlight module 20 includes a UV light source capable of generating ultraviolet light. Generally, the spectrum of the light generated by the UV light source has a peak at a wavelength of 320 nm to a wavelength of 420 nm. The color filter layer 140 includes a first wavelength conversion layer 140a, a second wavelength conversion layer 140b, and a third wavelength conversion layer 140c. The first wavelength conversion layer 140a contains a red quantum dot material to absorb ultraviolet light to excite red light, the second wavelength conversion layer 140b contains a green quantum dot material to absorb ultraviolet light to excite green light, and the third The wavelength conversion layer 140c includes a blue quantum dot material for absorbing ultraviolet light to excite blue light. The display medium 130 has a characteristic of adjusting light flux, and is, for example, a liquid crystal molecule. This embodiment uses the ultraviolet light to excite the quantum dot material, which has the advantages of high light penetration efficiency and high color saturation.
然而，利用紫外光線當作背光源時，顯示介質130可能會因長時間接受紫外光線的照射而加速劣化。另一方面，由於藍色量子點材料不易取得，可能會使得生產成本增加。However, when ultraviolet light is used as the backlight source, the display medium 130 may be deteriorated rapidly due to exposure to ultraviolet light for a long time. On the other hand, since blue quantum dot materials are not easily available, production costs may increase.
圖2為本發明顯示裝置200之另一實施例示意圖。如圖2所示，顯示裝置200包含顯示面板10和背光模組30，於本實施例中，背光模組30之設置可如前述之方式，在此不多加贅述。顯示面板10包含一第一基板110、一薄膜電晶體層120、一顯示介質130、一彩色濾光層140以及一第二基板150。於本實施例中，背光模組30包含一可產生藍光的LED光源，一般而言，藍光所產生之光線頻譜在波長420nm至波長480nm具有至少一波峰。彩色濾光層140包含第一波長轉換層140a、第二波長轉換層140b以及背光穿透層140x。第一波長轉換層140a包含有紅色量子點材料，用來吸收藍光以激發出紅色光，第二波長轉換層140b包含有綠色量子點材料，用來吸收藍光以激發出綠色光，背光穿透層140x可以是透明光阻或是無光阻，用來傳遞背光源所發出之藍色光。本實施例利用藍光LED光源激發量子點材料，仍然具有較高光穿透效率之優勢，且可改善使用UV光源所導致顯示介質劣化以及藍色量子點材料不易取得的問題。FIG. 2 is a schematic diagram of another embodiment of a display device 200 according to the present invention. As shown in FIG. 2, the display device 200 includes a display panel 10 and a backlight module 30. In this embodiment, the backlight module 30 can be arranged in the same manner as described above, and is not described in detail here. The display panel 10 includes a first substrate 110, a thin film transistor layer 120, a display medium 130, a color filter layer 140, and a second substrate 150. In this embodiment, the backlight module 30 includes an LED light source capable of generating blue light. Generally, the spectrum of light generated by blue light has at least one peak at a wavelength of 420 nm to a wavelength of 480 nm. The color filter layer 140 includes a first wavelength conversion layer 140a, a second wavelength conversion layer 140b, and a backlight transmission layer 140x. The first wavelength conversion layer 140a contains a red quantum dot material to absorb blue light to excite red light, and the second wavelength conversion layer 140b contains a green quantum dot material to absorb blue light to excite green light. The backlight penetrating layer 140x can be transparent or non-resistive, used to transmit the blue light emitted by the backlight. This embodiment uses the blue LED light source to excite the quantum dot material, which still has the advantage of higher light penetration efficiency, and can improve the problems of degradation of the display medium caused by the use of the UV light source and the difficulty of obtaining the blue quantum dot material.
然而，利用藍光LED光源當作背光源時，藍光通過紅色量子點材料或綠色量子點材料時，並無法完全轉換成紅色光以及綠色光，因此藍光通過第一波長轉換層140a和第二波長轉換層140b時會有藍色漏光的情形，進而造成色彩飽和度下降之問題。However, when a blue LED light source is used as a backlight source, blue light cannot be completely converted into red light and green light when it passes through a red quantum dot material or a green quantum dot material. Therefore, the blue light is converted by the first wavelength conversion layer 140a and the second wavelength. When the layer 140b is used, there may be a blue light leakage, which may cause a problem of a decrease in color saturation.
圖3為本發明顯示裝置300之另一實施例示意圖。如圖3所示，顯示裝置300包含顯示面板10、背光模組40和控制模組50，於本實施例中，背光模組40之設置可如前述之方式，在此不多加贅述。背光模組40包含第一光源301a和第二光源301b，控制模組50電性連接第一光源301a和第二光源301b。第一光源301a所產生之光線CL1在波長320nm至波長420nm具有一波峰，用以發射UV光；而第二光源301b所產生之光線CL2在波長420nm至波長480nm具有至少一波峰，用以發射藍光。在一顯示圖框期間內，可分為第一時段與第二時段，其中第一時段與第二時段可以部分重疊或完全不重疊。控制模組50在第一時段控制第一光源301a點亮，使背光模組40產生UV光之光線CL1進入顯示面板10，控制模組50在第二時段控制第二光源301b點亮，使背光模組40產生藍光之光線CL2進入顯示面板10，在一顯示畫面期間，藉由時序性的交替開啟第一光源301a和第二光源301b，可使顯示裝置300在第一時段處於低漏藍光模式，從而使顯示面板10具高色彩飽和度，在第二時段處於無UV光模式，可防止顯示面板10劣化。FIG. 3 is a schematic diagram of another embodiment of a display device 300 according to the present invention. As shown in FIG. 3, the display device 300 includes a display panel 10, a backlight module 40, and a control module 50. In this embodiment, the backlight module 40 can be arranged in the same manner as above, and is not described in detail here. The backlight module 40 includes a first light source 301a and a second light source 301b, and the control module 50 is electrically connected to the first light source 301a and the second light source 301b. The light CL1 generated by the first light source 301a has a peak at a wavelength of 320nm to 420nm to emit UV light; and the light CL2 generated by the second light source 301b has at least one peak at a wavelength of 420nm to 480nm to emit blue light. . During a period of displaying a frame, it can be divided into a first period and a second period, wherein the first period and the second period may partially overlap or not overlap at all. The control module 50 controls the first light source 301a to light up in the first period, so that the backlight module 40 generates UV light CL1 to enter the display panel 10, and the control module 50 controls the second light source 301b to light up in the second period, so that the backlight The module CL 40 generates blue light CL2 and enters the display panel 10. During a display screen, by sequentially turning on the first light source 301a and the second light source 301b, the display device 300 can be in the low-leakage blue light mode in the first period. Therefore, the display panel 10 has a high color saturation and is in a UV-free mode during the second period, which can prevent the display panel 10 from being deteriorated.
進一步說明圖3實施例之低漏藍光模式和無UV光模式之操作方法。請一併參考圖4A和圖4B，圖4A之顯示面板10包含一第一基板110、一薄膜電晶體層120、一顯示介質130、一彩色濾光層140以及一第二基板150。彩色濾光層140包含第一波長轉換層140a、第二波長轉換層140b以及背光穿透層140x。第一波長轉換層140a包含有紅色量子點材料，用來吸收背光BL以激發出紅色光，第二波長轉換層140b包含有綠色量子點材料，用來吸收背光BL以激發出綠色光，背光穿透層140x可以是透明光阻或是無光阻，用來傳遞背光源所發出之背光BL。在第一時段時，控制模組50控制第一光源(UV光源)301a點亮，並關閉第二光源(藍光源)301b。第一光源301a所產生之光線CL1(即UV光)通過第一波長轉換層140a和第二波長轉換層140b分別發射出紅色光R和綠色光G，為避免UV光直接通過背光穿透層140x對人眼造成傷害，可在第二基板150上設置一UV光線阻斷層160(UV-cut layer)。The operation method of the low-leakage blue light mode and the UV-free light mode of the embodiment of FIG. 3 is further described. Please refer to FIG. 4A and FIG. 4B together. The display panel 10 of FIG. 4A includes a first substrate 110, a thin film transistor layer 120, a display medium 130, a color filter layer 140, and a second substrate 150. The color filter layer 140 includes a first wavelength conversion layer 140a, a second wavelength conversion layer 140b, and a backlight transmission layer 140x. The first wavelength conversion layer 140a contains a red quantum dot material to absorb the backlight BL to excite red light, and the second wavelength conversion layer 140b contains a green quantum dot material to absorb the backlight BL to excite green light. The transparent layer 140x may be a transparent photoresistor or no photoresistor, and is used to transmit the backlight BL emitted by the backlight source. During the first period, the control module 50 controls the first light source (UV light source) 301a to be turned on, and turns off the second light source (blue light source) 301b. The light CL1 (ie, UV light) generated by the first light source 301a emits red light R and green light G through the first wavelength conversion layer 140a and the second wavelength conversion layer 140b, respectively. In order to prevent UV light from directly passing through the backlight penetrating layer 140x To cause damage to human eyes, a UV-cut layer 160 (UV-cut layer) may be disposed on the second substrate 150.
請參考圖4B。在第二時段時，控制模組50控制第二光源(藍光源)301b點亮，並關閉第一光源(UV光源)301a。第二光源301b所產生之光線CL2(即藍光)通過第一波長轉換層140a、第二波長轉換層140b和第三波長轉換層140x分別發射出紅色光R、綠色光G和藍色光B。Please refer to FIG. 4B. During the second period, the control module 50 controls the second light source (blue light source) 301b to light up, and turns off the first light source (UV light source) 301a. The light CL2 (ie, blue light) generated by the second light source 301b passes through the first wavelength conversion layer 140a, the second wavelength conversion layer 140b, and the third wavelength conversion layer 140x to emit red light R, green light G, and blue light B, respectively.
進一步而言，第一時段與第二時段之長短設計可根據使用者需求而調整，舉例來說，調整第一時段大於第二時段時，則顯示裝置具有高飽和度之效果。Further, the length of the first period and the second period can be adjusted according to user needs. For example, when the first period is adjusted to be greater than the second period, the display device has a high saturation effect.
圖5為本發明顯示裝置500之另一實施例示意圖。如圖5所示，顯示裝置500包含顯示面板10和背光模組40，本實施例與圖4之顯示裝置400的差異在於，顯示裝置500之彩色濾光層140配置於第一基板110與顯示介質130之間，亦即，使用Color Filter on Array(COA)之架構搭配時序型背光模組40。FIG. 5 is a schematic diagram of another embodiment of a display device 500 according to the present invention. As shown in FIG. 5, the display device 500 includes a display panel 10 and a backlight module 40. The difference between this embodiment and the display device 400 of FIG. 4 is that the color filter layer 140 of the display device 500 is disposed on the first substrate 110 and the display. Between the media 130, that is, a color filter on array (COA) architecture is used with the timing backlight module 40.
綜合以上所述，本發明顯示裝置利用時序型背光模組，控制UV光與藍光交替開關，從而控制顯示裝置之穿透效率與色彩飽和度，改善利用單一UV光源使液晶劣化或單一藍色LED光源造成漏藍光使色彩飽和度下降的問題。To sum up, the display device of the present invention uses a sequential backlight module to control the alternate switching of UV light and blue light, thereby controlling the penetration efficiency and color saturation of the display device, and improving the use of a single UV light source to degrade the liquid crystal or a single blue LED. The light source causes a problem of leaking blue light and reducing color saturation.
