Generally, a light source (not shown) is disposed in the light guiding structure 14 to form a front light module. The second adhesive material 16 is formed between the circuit board 12 and the light guiding structure 14 to electrically connect the circuit board 12 and the light source. When the display device 1 is operated for a long time (for example, 240 hours) in a high-temperature and high-humidity environment, the rubber material 16 is deformed by heat expansion and contraction, causing image sticking problems in the display panel.
本發明提供一種可防止顯示面板發生影像殘留問題之顯示裝置，以解決上述問題。 The present invention provides a display device capable of preventing image sticking problems in a display panel to solve the above problems.
根據一實施例，本發明之顯示裝置包含一顯示面板、一電路板、一導光結構以及二膠材。電路板設置於顯示面板上。導光結構設置於顯示面板上。導光結構具有一底面以及一周面，其中底面朝向顯示面板，且周面鄰接底面。二鍍金區形成於底面上。二第一凹槽形成於周面上且與二鍍金區相對應。二膠材形成於二鍍金區與電路板之間。 According to an embodiment, the display device of the present invention comprises a display panel, a circuit board, a light guiding structure and a second glue. The circuit board is disposed on the display panel. The light guiding structure is disposed on the display panel.

請參閱第2圖以及第3圖，第2圖為根據本發明一實施例之顯示裝置3的示意圖，第3圖為第2圖中的導光結構34於另一視角的示意圖。 Please refer to FIG. 2 and FIG. 3, FIG. 2 is a schematic diagram of a display device 3 according to an embodiment of the invention, and FIG. 3 is a schematic view of the light guiding structure 34 in FIG. 2 from another perspective.
如第2圖所示，顯示裝置3包含一顯示面板30、一電路板32、一導光結構34以及二膠材36。於此實施例中，顯示面板30可為液晶顯示面板或其它顯示面板，電路板32可為軟性印刷電路板或其它電路板，且膠材36可為銀膠或其它膠材。導光結構34可由液晶高分子聚合物(liquid crystal polymer，LCP)製成，但不以此為限。 As shown in FIG. 2, the display device 3 includes a display panel 30, a circuit board 32, a light guiding structure 34, and a second adhesive material 36. In this embodiment, the display panel 30 can be a liquid crystal display panel or other display panel, the circuit board 32 can be a flexible printed circuit board or other circuit board, and the glue 36 can be silver glue or other glue. The light guiding structure 34 can be made of liquid crystal polymer (LCP), but is not limited thereto.
電路板32與導光結構34設置於顯示面板30上。一般而言，導光結構34中設置有光源(例如，發光二極體，未顯示)，而形成一前光模組(front light module)。導光結構34具有一底面340以及一周面342，其中當導光結構34設置於顯示面板30上時，底面340係朝向顯示面板30，周面342鄰接底面340。如第3圖所示，二鍍金區344形成於底面340上。此外，二第一凹槽346形成於周面342上 且與二鍍金區344相對應。二膠材36形成於二鍍金區344與電路板32之間，以電性連接電路板32與導光結構34中的光源(未顯示)。 The circuit board 32 and the light guiding structure 34 are disposed on the display panel 30. Generally, a light source (for example, a light emitting diode, not shown) is disposed in the light guiding structure 34 to form a front light module. The light guiding structure 34 has a bottom surface 340 and a circumferential surface 342. When the light guiding structure 34 is disposed on the display panel 30, the bottom surface 340 faces the display panel 30, and the circumferential surface 342 abuts the bottom surface 340. As shown in FIG. 3, the two gold plating regions 344 are formed on the bottom surface 340. In addition, two first grooves 346 are formed on the circumferential surface 342 And corresponding to the two gold plating zone 344. The second adhesive material 36 is formed between the two gold plating regions 344 and the circuit board 32 to electrically connect the circuit board 32 and the light source (not shown) in the light guiding structure 34.
當膠材36因熱漲冷縮而發生變形時，第一凹槽346可產生類似彈簧之 功能，使得鍍金區344可在膠材36收縮時被下拉，且鍍金區344可在膠材36膨脹時被上抬。藉此，即可降低膠材36於熱漲冷縮過程造成的應力集中現象，且防止顯示面板30發生影像殘留問題。 When the glue material 36 is deformed due to heat expansion and contraction, the first groove 346 can be similar to a spring. The function is such that the gold plated region 344 can be pulled down when the glue 36 is shrunk, and the gold plated region 344 can be lifted as the glue 36 expands. Thereby, the stress concentration phenomenon caused by the heat expansion and contraction of the rubber material 36 can be reduced, and the image sticking problem of the display panel 30 can be prevented.
較佳地，第一凹槽346於垂直底面340之方向的厚度T可大於或等於 0.1毫米，且第一凹槽346於平行底面340之方向的長度L1、L2可超過鍍金區344，因此，可有效降低膠材36於熱漲冷縮過程造成的應力集中現象，且有效防止顯示面板30發生影像殘留問題。 Preferably, the thickness T of the first groove 346 in the direction of the vertical bottom surface 340 may be greater than or equal to 0.1 mm, and the length L1, L2 of the first groove 346 in the direction of the parallel bottom surface 340 can exceed the gold plating area 344, so that the stress concentration caused by the rubber material 36 during the heat expansion and contraction process can be effectively reduced, and the display is effectively prevented. An image sticking problem occurs in the panel 30.
於此實施例中，二第一凹槽346可貫穿或未貫穿導光結構34之內壁， 視實際應用而定。 In this embodiment, the two first grooves 346 may or may not penetrate the inner wall of the light guiding structure 34. Depending on the application.
配合第2圖，請參閱第4圖，第4圖為根據本發明另一實施例之顯示裝 置3'的示意圖。顯示裝置3'與上述的顯示裝置3的不同之處在於，二第一凹槽346相互連通而形成單一凹槽，如第4圖所示。換言之，本發明可於周面342上形成單一凹槽，以達成與上述的顯示裝置3相同的功效。 Referring to FIG. 2, please refer to FIG. 4, which is a display device according to another embodiment of the present invention. Set the schematic of 3'. The display device 3' is different from the above-described display device 3 in that the two first grooves 346 communicate with each other to form a single groove as shown in FIG. In other words, the present invention can form a single groove on the circumferential surface 342 to achieve the same efficacy as the display device 3 described above.
請參閱第5圖，第5圖為根據本發明另一實施例之導光結構34'的示意 圖。導光結構34'與上述的導光結構34的不同之處在於，導光結構34'另包含二第二凹槽348，形成於底面340上且鄰接二鍍金區344，如第5圖所示。當第2圖所示之導光結構34以第5圖所示之導光結構34'替換時，可更有效降低膠材36於熱漲冷縮過程造成的應力集中現象，且更有效防止顯示面板30發生影像殘留問題。 Please refer to FIG. 5, which is a schematic diagram of a light guiding structure 34' according to another embodiment of the present invention. Figure. The light guiding structure 34' is different from the light guiding structure 34 described above in that the light guiding structure 34' further comprises two second grooves 348 formed on the bottom surface 340 and adjacent to the two gold plating regions 344, as shown in FIG. . When the light guiding structure 34 shown in FIG. 2 is replaced by the light guiding structure 34' shown in FIG. 5, the stress concentration caused by the rubber material 36 during the heat expansion and contraction process can be more effectively reduced, and the display is more effectively prevented. An image sticking problem occurs in the panel 30.
較佳地，第二凹槽348於平行底面340之方向的寬度W可大於或等於 0.1毫米，因此，可更有效降低膠材36於熱漲冷縮過程造成的應力集中現象，且更有效防止顯示面板30發生影像殘留問題。 Preferably, the width W of the second groove 348 in the direction of the parallel bottom surface 340 may be greater than or equal to 0.1 mm, therefore, the stress concentration caused by the rubber material 36 during the heat expansion and contraction process can be more effectively reduced, and the image sticking problem of the display panel 30 is more effectively prevented.
於此實施例中，第二凹槽348與第一凹槽346可連通或不連通，視實際應用而定。 In this embodiment, the second groove 348 may or may not be in communication with the first groove 346, depending on the actual application.
綜上所述，本發明係於周面上形成與鍍金區相對應之第一凹槽。當膠材因熱漲冷縮而發生變形時，第一凹槽可產生類似彈簧之功能，使得鍍金區可在膠材收縮時被下拉，且鍍金區可在膠材膨脹時被上抬。藉此，即可降低膠材於熱漲冷縮過程造成的應力集中現象，且防止顯示面板發生影像殘留問題。此外，本發明可於底面上形成與鍍金區鄰接的第二凹槽，可更有效降低膠材於熱漲冷縮過程造成的應力集中現象，且更有效防止顯示面板發生影像殘留問題。 In summary, the present invention forms a first groove corresponding to the gold plating area on the circumferential surface. When the rubber material is deformed due to heat expansion and contraction, the first groove can produce a spring-like function, so that the gold plating region can be pulled down when the rubber material shrinks, and the gold plating region can be lifted when the rubber material expands. Thereby, the stress concentration caused by the thermal expansion and contraction of the rubber material can be reduced, and the image sticking problem of the display panel is prevented. In addition, the present invention can form a second groove adjacent to the gold plating area on the bottom surface, which can more effectively reduce the stress concentration phenomenon caused by the heat expansion and contraction process of the rubber material, and more effectively prevent image sticking problem of the display panel.
以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
