Description
Technical Field
The present invention relates to a display module, and more particularly, to a liquid crystal display module with improved light leakage.
Background
Fig. 1 is a perspective view of a conventional liquid crystal display module. As shown in fig. 1, a conventional lcd module 10 includes a display panel 12 for displaying images and a backlight module 14 for providing light to the display panel 12. Ideally, the display panel 12 and the back module 14 are completely attached, and the connection surface of the two is a flat surface, as shown in fig. 1. However, as shown in the corner 16 of the liquid crystal display module 10 in FIG. 2, the backlight module 14 may have a curvature, so that the display panel 12 may be deformed after the display panel 12 is disposed on the backlight module 14. Such deformation may cause slight abnormal liquid crystal alignment inside the display panel 12, which may result in uneven brightness and light leakage when the light of the backlight module 14 passes through the corner 16 of the display panel 12. Fig. 3 is a graph of a pressure test curve of the liquid crystal display module 10 in fig. 2, when the display panel 12 is lightly pressed to generate a pressing distance of 0.4mm, the light leakage degree of the display panel 12 exceeds a standard value of 0.06, and it is determined that the light leakage phenomenon occurs.

Detailed Description
Fig. 4 and 5 show a liquid crystal display module according to a first embodiment of the invention. Referring to fig. 4 and 5, the lcd module 20 includes a display panel 22, a bonding layer 24, and a backlight module 26. The display panel 22 is disposed on the backlight module 26, and the adhesive layer 24 is sandwiched between the backlight module 26 and the display panel 22. The adhesive layer 24 may be a light-shielding tape.
The backlight module 26 has a curvature such that the center of the backlight module 26 is higher than both sides. For convenience of understanding, the first side 262 of the backlight module 26 is taken as an example. The first side 262 of the backlight module 26 has the curvature, and the curvature of the curvature increases from the center of the first side 262 to the two sides. The adhesive layer 24 has an adjusting surface 242 facing the backlight module 26 and a flat surface 244 facing the display panel 22 corresponding to the position of the first side 262. The adjustment surface 242 of the adhesive layer 24 is attached to the first side 262 and adapted to the curvature. After the adhesive layer 24 is attached to the backlight module 26, the display panel 22 is attached to the flat surface 244 of the adhesive layer 24 to obtain the liquid crystal display module 20 of the invention, as shown in fig. 5. In fig. 4, the adjustment surface 242 has the same curvature as the first side 262, so the distance between the adjustment surface 242 and the flat surface 244 increases as the curvature of the curvature increases. In other words, the thickness of the lamination layer 24 increases from the center of the adjustment surface 242 to both sides, as shown by the thicknesses L1 and L2 in fig. 4. In the embodiment of fig. 4, any position of conforming layer 24 has the same width W.
In the embodiment of fig. 4, the thickness of conforming layer 24 varies with the curvature of first side 262 such that adjustment surface 242 of conforming layer 24 has the same degree of curvature as first side 262. Therefore, after the adjustment surface 242 of the adhesive layer 24 is attached to the first side 262, the flat surface 244 of the adhesive layer 24 can be kept flat. In this way, the display panel 22 attached to the flat surface 244 is not deformed by the curvature of the backlight module 26, and thus the light leakage phenomenon occurs.
Fig. 6 and 7 show a second embodiment of the liquid crystal display module of the present invention. Fig. 8 is an enlarged view of a portion of region 38 of fig. 6. Fig. 9 is an enlarged view of a portion of the area 40 of fig. 7. Referring to fig. 6 and 7, the lcd module 30 includes a display panel 32, a bonding layer 34, and a backlight module 36. The display panel 32 is disposed on the backlight module 36, and the adhesive layer 34 is sandwiched between the backlight module 36 and the display panel 32. The adhesive layer 34 may be a light-shielding tape.
The backlight module 36 has a curvature such that the center of the backlight module 36 is higher than both sides. For convenience of understanding, the first side 362 of the backlight module 36 is illustrated as an example. The first side 362 of the backlight module 36 has the curvature, and the curvature of the curvature increases from the center of the first side 362 to the two sides. The adhesive layer 34 has an adjusting surface 342 and a flat surface 344 corresponding to the position of the first side 362, the adjusting surface 342 faces the backlight module 36 and is used for attaching the first side 362. The flat surface 344 faces the display panel 32 and is used for attaching to the display panel 32. As shown in fig. 6 and 8, the lamination layer 34 has a uniform initial thickness L. After the adhesive layer 34 is sandwiched between the backlight module 36 and the display panel 32, the adhesive layer 34 deforms due to the curvature of the backlight module 36, so that the initial thickness L is adjusted to the final thickness, as shown by the final thicknesses L3 and L4 in fig. 7 and 9, and as the curvature of the first side 362 increases from the center to the two sides, the final thickness increases from the center to the two sides of the adjustment surface 342. In the embodiment of fig. 6, as the curvature of the curvature increases from the center of the first side 326 to the two sides, the attaching area of the adjusting surface 342 and the backlight module 36 of the attaching layer 34 and the attaching area of the flat surface 344 and the display panel 32 (as shown in areas A1 and A2 of fig. 6 and 8) increase from the center of the adjusting surface 342 and the flat surface 344 to the two sides. That is, the width of conforming layer 34 (as shown by widths W1 and W2 of fig. 6) increases from the center of alignment surface 342 and flat surface 344 to both sides.
Referring to fig. 6, 7, 8 and 9, when the adjustment surface 342 of the adhesive layer 34 is adhered to the backlight module 36, the adhesive layer 34 is deformed due to the curvature of the backlight module 36. The thickness of the adhesive layer 34 is adjusted from the initial thickness L to the final thicknesses L3 and L4 by the pressing of the backlight module 36. As is apparent from fig. 9, the closer to the center of the first side edge 362, the smaller the final thickness of the adhesive layer 34 is due to the pressing of the backlight module 36. The display panel 32 is then attached to the flat surface 344 of the attachment layer 34. As shown in fig. 9, after the display panel 32 is attached to the adhesive layer 34, the backlight module 36 applies vertical forces F1 and F2 to the adhesive layer 34 due to the curvature of the backlight module 32. In the embodiment of fig. 9, the force F2 at the center of the lamination layer 34 is larger, the force F1 at both sides of the lamination layer 34 is smaller, and the area A1 at both sides of the lamination layer 34 is larger. The known deformation is formulated as
δ = (F · L)/(a · E) formula 1
Wherein, δ is the deformation, F is the acting force, L is the thickness of the material, A is the stressed area of the material, and E is the elastic coefficient. Referring to fig. 9, since the forces F1 and F2 are applied to the adhesive layer 34 (the materials are the same), the elastic coefficients E at the positions of the areas A1 and A2 are the same, and the initial thicknesses at the positions of the areas A1 and A2 are both L (as shown in fig. 6). Due to the curvature of the backlight module 36, forces F1 and F2 are respectively applied to the areas A1 and A2 of the adhesive layer 34, where the area A1 is larger than the area A2, so that the deformation δ 1= (F1 · L)/(A1 · E) of the adhesive layer 34 at the area A1 position is smaller than the deformation δ 2= (F2 · L)/(A2 · E) of the area A2 position, and the final thicknesses of the areas A1 and A2 of the adhesive layer 34 after being subjected to force changes are L3 and L4, where L3 > L4. Derived from equation 1
E/L = F/(a · δ) formula 2
Since the elastic coefficient E and the initial thickness L are controllable constant values, and the forces F1 and F2 generated by the curvature of the backlight module 36 on the adhesive layer 34 can be obtained by measurement, areas A1 and A2 (or widths) of the adhesive layer 34 at different positions can be designed according to the curvature, so that P1= F1/(A1 · δ 1) = F2/(A2 · δ 2) = P2, and finally, the force applied between the display panel 32 and the adhesive layer 34 is P1= P2. In other words, the display panel 32 is uniformly stressed to prevent the display panel 32 from being deformed and causing light leakage.
Fig. 10 and 11 show a third embodiment of a liquid crystal display module according to the present invention. Referring to fig. 10 and 11, the lcd module 50 includes a display panel 52, a bonding layer 54, and a backlight module 56. The display panel 52 is disposed on the backlight module 56, and the adhesive layer 54 is sandwiched between the backlight module 56 and the display panel 522. The adhesive layer 54 may be a light-shielding tape. Backlight module 56 has a curvature that results in backlight module 26 being lower in the middle than on both sides. For convenience of understanding, the first side 562 of the backlight module 56 is illustrated as an example. The first side 562 of the backlight module 56 has the curvature, and the curvature of the curvature increases from the center of the first side 562 to two sides. The adhesive layer 54 has an adjustment surface 542 facing the backlight module 56 and a flat surface 544 facing the display panel 52 at a position corresponding to the first side 562. The adjustment surface 542 of the adhesive layer 54 is attached to the first side 562 and is adapted to the curvature. In fig. 4, adjustment surface 542 has the same curvature as first side 562, so the distance between adjustment surface 542 and flat surface 544 decreases as the curvature of the curvature increases. In other words, the thickness of the lamination layer 54 decreases from the center of the adjustment surface 542 to both sides, as shown by the thicknesses L5 and L6 in fig. 10. Any position of the lamination layer 54 has the same width W. In the embodiment of fig. 10, the thickness of the conforming layer 54 varies with the curvature of the first side 562 such that the adjustment surface 542 of the conforming layer 54 has the same degree of curvature as the first side 562. Therefore, the flat surface 544 of the adhesive layer 54 can be kept flat after the adjustment surface 542 of the adhesive layer 54 is attached to the first side 562. In this way, the display panel 52 attached to the flat surface 544 is not deformed by the curvature of the backlight module 56, and thus light leakage occurs.
Fig. 12 and 13 show a fourth embodiment of the liquid crystal display module of the present invention. Referring to fig. 12 and 13, the lcd module 60 includes a display panel 62, a bonding layer 64, and a backlight module 66. The display panel 62 is disposed on the backlight module 66, and the adhesive layer 64 is sandwiched between the backlight module 66 and the display panel 62. The adhesive layer 64 may be a light blocking tape. The backlight module 66 has a curvature such that the center of the backlight module 66 is lower than both sides. The first side 362 of the backlight module 66 is used as an example. The first side 662 of the backlight module 66 has the curvature, and the curvature of the curvature increases from the center of the first side 662 to the two sides. The adhesive layer 64 has an adjusting surface 642 and a flat surface 644 at a position corresponding to the first side 662, and the adjusting surface 642 faces the backlight module 66 and is used for attaching the first side 662. The flat surface 644 faces the display panel 62 and is used for attaching to the display panel 62. As shown in fig. 12, the lamination layer 64 has a uniform initial thickness L. After the adhesive layer 64 is sandwiched between the backlight module 66 and the display panel 62, the adhesive layer 64 deforms due to the curvature of the backlight module 66, so that the initial thickness L is adjusted to a final thickness, as shown by final thicknesses L5 and L6 in fig. 13, and the final thickness decreases from the center of the adjustment surface 642 to both sides as the curvature of the first side 662 increases from the center to both sides. In the embodiment of fig. 12, as the curvature of the curvature increases from the center of the first side 626 to both sides, the attaching area of the adjusting surface 642 of the attaching layer 64 and the backlight module 66 and the attaching area of the flat surface 644 and the display panel 62 (as shown in areas A3 and A4 of fig. 12) increase from the center of the adjusting surface 642 and the flat surface 644 to both sides. That is, the width of the lamination layer 64 (as shown by the widths W3 and W4 in fig. 12) decreases from the center of the adjustment surface 642 and the flat surface 644 to both sides.
As with the contents described in fig. 6, fig. 7, fig. 8 and fig. 9, areas A3 and A4 (or widths W) of the adhesive layer 64 at different positions can be designed according to the curvature of the backlight module 66 through formula 1 and formula 2, so that the stresses at different positions between the display panel 62 and the adhesive layer 64 are the same, and the display panel 62 is prevented from being deformed and light leakage is prevented.
Fig. 14 and 15 show a fifth embodiment of the liquid crystal display module of the present invention. Referring to fig. 14 and 15, the lcd module 70 includes a display panel 72, a bonding layer 74, and a backlight module 76. The display panel 72 is disposed on the backlight module 76, and the adhesive layer 74 is sandwiched between the backlight module 76 and the display panel 72. The adhesive layer 74 may be a light blocking tape. In the embodiment of FIG. 14, the backlight module 76 includes a first side 762 having a first curvature and a second side 764 having a second curvature. The first side 762 and the second side 764 intersect each other. In other embodiments, the first side 762 and the second side 764 can be opposite to each other.
In fig. 14, the first curvature causes the center of the first side 762 of the backlight module 76 to be higher than the two sides, and the curvature of the first curvature increases from the center of the first side 762 to the two sides. The second curvature causes the center of the second side 764 of the backlight module 76 to be higher than the two sides, and the curvature of the second curvature increases from the center of the second side 764 to the two sides. The adhesive layer 74 has an adjustment surface facing the backlight module 76 and a flat surface 746 facing the display panel 72, wherein the adjustment surface has a first adjustment region 742 and a second adjustment region 744. The first adjusting region 742 of the adhesive layer 74 is attached to the first side 762 and adapted to the first curvature, and the second adjusting region 744 of the adhesive layer 74 is attached to the first side 764 and adapted to the second curvature. In FIG. 14, first adjustment region 742 has the same curvature as first side 762, so the distance between first adjustment region 742 and flat 746 increases with increasing curvature of the first curvature. Similarly, the distance between the second adjustment region 744 and the flat surface 746 increases as the curvature of the second curvature increases. In other words, the thickness of the adhesive layer 74 in the first adjustment region 742 increases from the center of the first adjustment region 742 to two sides, as shown by the thicknesses L7 and L8 in fig. 14, and the thickness of the adhesive layer 74 in the second adjustment region 744 increases from the center of the second adjustment region 744 to two sides, as shown by the thicknesses L9 and L10 in fig. 14. In the embodiment of fig. 14, any location of conforming layer 74 has the same width W.
In the embodiment of fig. 14, the thickness of the conforming layer 74 at the first adjusting region 742 varies with the curvature of the first side 762, so that the first adjusting region 742 of the conforming layer 74 has the same curvature as the first side 762. The thickness of the conforming layer 74 at the second alignment area 744 varies with the curvature of the second side edge 764, such that the second alignment area 744 of the conforming layer 74 has the same curvature as the second side edge 764. Therefore, after the backlight module 76 is attached to the adjustment surface of the adhesive layer 74, the flat surface 746 of the adhesive layer 74 can be kept flat. In this way, the display panel 72 attached to the flat surface 746 is not deformed by the first curvature and the second curvature of the backlight module 76, and thus light leakage occurs.
In summary, in the liquid crystal display module according to the above embodiment, the shape of the adhesive layer is changed according to the curvature of the backlight module. Therefore, the display panel can be prevented from being deformed due to the curvature of the backlight module, and the problem of light leakage caused by the deformation of the display panel can be avoided.
The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description and is not intended to limit the invention to the precise form disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of the embodiments of the invention. For example, according to the disclosure of fig. 14, when the backlight module 36 in fig. 6 or the backlight module 60 in fig. 12 includes a second side edge having a second curvature, if the curvature of the second curvature increases from the center of the second side edge to both sides, the attaching area or the width of the second adjustment region corresponding to the second side edge in the attachment layer 34 or 64 increases or decreases from the center of the second adjustment region to both sides. For another example, according to the disclosure in fig. 14, when the backlight module 50 in fig. 10 includes a second side edge having a second curvature, if the curvature of the second curvature increases from the center of the second side edge to both sides, the thickness of the second adjustment region corresponding to the second side edge in the adhesive layer 54 decreases from the center of the second adjustment region to both sides. The embodiments described above were chosen and described in order to explain the principles of the invention and to enable others skilled in the art to utilize the invention in various embodiments and with various applications, the technical spirit of the invention is intended to be determined by the claims and their equivalents.
