Description

display device

The present invention relates to a display technology, and in particular to a display device.

With the advancement of digital technology and related software and hardware, immersive experience has successfully attracted the favor of many users. For example, RVs create the atmosphere of the interior space by setting up mood lighting areas around their monitor screens, giving users a sense of immersion. However, existing LCD displays have dark areas in the ambient light area. After deducing the reason, it was found that in order to avoid the problem of polarizer shrinkage in high temperature environments, the size of the polarizer needs to be larger than the screen display area, causing the polarizer to extend to the situation light area where the display mode is different from the display area, so dark areas appear in the situation light area . On the other hand, in order to shield the light leakage caused by the poor arrangement of the liquid crystal layer at the edge of the display area and the setting of the circuit area and the frame rubber area, a light-shielding layer will be provided at the junction of the display area and the ambient light area to form a black area, causing the display The picture continuity in the area and situation light area becomes worse.

The present invention provides a display device with better picture continuity in various display areas.

The display device of the present invention has a display area and a situation display area other than the display area. The display device includes a first substrate, a second substrate, a first polarizer, a second polarizer, a sealant layer, a liquid crystal layer and an optical brightness enhancement film. The first substrate is provided with a pixel structure layer, a circuit element layer and a signal wiring layer. The second substrate overlaps the first substrate and is provided with a first light-shielding pattern, a second light-shielding pattern and a third light-shielding pattern. The first polarizer is disposed on a side of the first substrate facing away from the second substrate. The second polarizer is disposed on a side of the second substrate facing away from the first substrate. The sealant layer is sandwiched between the first substrate and the second substrate and defines an accommodation space. The liquid crystal layer is arranged in the accommodation space. The optical brightness enhancement film is disposed on a side of the first polarizer facing away from the first substrate. The situation display area includes a first sub-area, a second sub-area and a third sub-area. A first polarizer or a second polarizer is disposed in the first sub-region, the second sub-region and the third sub-region. The first sub-region is also provided with a first light-shielding pattern, a frame glue layer and a signal wiring layer. The second sub-region is also provided with a second light-shielding pattern, a liquid crystal layer and a circuit element layer. The third sub-area is also provided with a third light-shielding pattern, a liquid crystal layer and a pixel structure layer. The display area is provided with a first polarizer, a second polarizer, a third light-shielding pattern, a liquid crystal layer, a pixel structure layer and an optical brightness enhancement film. The respective transmittances of the first sub-area, the second sub-area, the third sub-area and the display area are equal to each other.

Based on the above, in the display device according to an embodiment of the present invention, the display area and the three sub-areas of the situation display area other than the display area are each provided with the same or different numbers and the same or different types of structural film layers. Through the combination of these structural film layers in the three sub-areas of the display area and the contextual display area, the transmittances of these areas are approximately equal. Therefore, there is no need to set up a light-shielding structure at the junction of the display area and the situational display area to block light leakage caused by poor arrangement of the liquid crystal layer, the setting of the sealant layer and the circuit structure, which helps to significantly improve the picture continuity between the display area and the situational display area. sex.

FIG. 1 is a schematic front view of a display device according to a first embodiment of the present invention. Fig. 2 is a schematic cross-sectional view of the display device of Fig. 1 along the sectional line A-A'. FIG. 3 is a schematic cross-sectional view of a display device according to a second embodiment of the present invention. In order to simplify the expression of the diagram, FIG. 1 only illustrates the display area DA and the situation display area SDA of the display device 10 , and omits the illustration of other components.

Referring to FIGS. 1 and 2 , the display device 10 has a display area DA and a situation display area SDA other than the display area DA. In this embodiment, the situation display area SDA can be arranged around the display area DA, but is not limited to this. In other embodiments, the context display area SDA of the display device 10 may be located on at least one side of the display area DA. For example, the context display area SDA may only be provided on opposite sides of the display area DA in FIG. 1 along the direction D1 or the direction D3. side.

The display device 10 is, for example, a liquid crystal display device, and includes a first substrate 100 , a second substrate 200 , a first polarizer POL1 , a second polarizer POL2 , a sealant layer 150 , a liquid crystal layer LCL, and an optical brightness enhancement film 300 . The first substrate 100 and the second substrate 200 are overlapped with each other. It should be noted that the overlapping relationship here refers to, for example, that the two substrates overlap each other along the direction D2 in FIG. 2 . Unless otherwise mentioned below, the overlapping relationship between any two components is defined in the same way and will not be described again.

In this embodiment, the second substrate 200 may protrude from the side edge of the first substrate 100, but is not limited thereto. More specifically, the first substrate 100 and the second substrate 200 respectively have a first length L1 and a second length L2 along the direction D1, and the second length L2 of the second substrate 200 is greater than the first length L1 of the first substrate 100 .

The first polarizer POL1 is disposed on a side of the first substrate 100 facing away from the second substrate 200 . The second polarizer POL2 is disposed on a side of the second substrate 200 facing away from the first substrate 100 . The sealant layer 150 is sandwiched between the first substrate 100 and the second substrate 200 and defines an accommodation space for filling the liquid crystal layer LCL. The optical brightness enhancement film 300 is disposed on the side of the first polarizer POL1 facing away from the first substrate 100 . In this embodiment, the optical brightness enhancement film 300 is, for example, a reflective polarizing brightness enhancement film (DBEF), and is used to improve the overall display brightness of the display device 10 , but is not limited to this. For example, the light beam emitted by the backlight of the display device 10 is composed of two linearly polarized lights with orthogonal polarization electric fields, and the reflective polarizing brightness enhancement film is suitable for allowing one of the linearly polarized lights to pass through and reflecting the other linearly polarized light. polarized light. Accordingly, the other linearly polarized light reflected back to the backlight source will not be absorbed by the first polarizer POL1 and can be reused.

The display device 10 may further include a first light panel 410 and a second light panel 420 (ie, the aforementioned backlight). The first light panel 410 is arranged overlapping the situation display area SDA. The second light panel 420 is disposed overlapping the display area DA. From another point of view, the situation display area SDA and the display area DA of the display device 10 may be defined by the placement positions of the first light panel 410 and the second light panel 420 .

For example, the first light panel 410 is a situational light panel, which may include light-emitting elements LED1, LED2, and LED3 with different emitting colors, and these light-emitting elements may be individually controlled to make the first light panel 410 emits light beams of different colors. The second light panel 420 is, for example, a display light panel provided with a plurality of light emitting elements LED. Similar to the first light panel 410, the second light panel 420 may include a plurality of light-emitting elements LED with different light-emitting colors, such as red light-emitting elements, green light-emitting elements and blue light-emitting elements. Different from the first light panel 410, these light-emitting elements of different light-emitting colors of the second light panel 420 can form a white light-emitting unit to emit white light for display. In other words, different from the operation mode of the first light panel 410 , when the second light panel 420 is used, multiple light-emitting elements with different light-emitting colors on the second light panel 420 need to be enabled at the same time to generate the required white light for display.

In this embodiment, the first substrate 100 may be provided with a pixel structure layer 110, a circuit element layer 120 and a signal wiring layer 130. For example, the pixel structure layer 110 may include a plurality of pixel structures arranged in an array, where the pixel structures are, for example, at least one active element and at least one pixel electrode that are electrically connected to each other. The circuit element layer 120 may include a gate driver circuit (Gate driver On Array, GOA), a source driver circuit (Source driver On Array, SOA), an electrostatic discharge protection circuit (Electro-Static Discharge, ESD), or other circuits with different functions. control circuit. The signal wiring layer 130 may include multiple fanout wires. That is to say, the first substrate 100 may be a pixel array substrate of the display device 10 .

In this embodiment, the second substrate 200 may be provided with a first light-shielding pattern 210, a second light-shielding pattern 220, a third light-shielding pattern 230, a fourth light-shielding pattern 240 and a first color filter layer 260. That is to say, the second substrate 200 may be a color filter substrate of the display device 10 . For example, the first color filter layer 260 may include a plurality of first color filter patterns 261 and a plurality of second color filter patterns 262 with colors different from each other (such as red, green and blue, but not limited thereto). and a plurality of third color filter patterns 263. These color filter patterns can be disposed in a plurality of openings OP of the third light shielding pattern 230, but are not limited thereto.

Specifically, in this embodiment, the first light-shielding pattern 210, the second light-shielding pattern 220, the third light-shielding pattern 230 and the fourth light-shielding pattern 240 can be formed on the same film layer, and the material thereof is, for example, a black resin material. But it is not limited to this.

FIG. 2 illustrates the arrangement of the situation display area SDA adjacent to the left side of the display area DA along the direction D1. For example, the situation display area SDA can be divided into a first sub-area Z1, a second sub-area Z2, a third sub-area Z3, a fourth sub-area Z4 and a fifth sub-area Z5, but this is not a limitation. In detail, the first sub-area Z1, the second sub-area Z2 and the third sub-area Z3 are arranged adjacently in sequence along the direction D1. The fourth sub-area Z4 is arranged adjacent to the side of the first sub-area Z1 away from the second sub-area Z2. The fifth sub-area Z5 is adjacent between the fourth sub-area Z4 and the display area DA.

Although the figure does not show the arrangement of the situation display area SDA on other sides of the display area DA, it can be understood that on other sides of the display area DA (such as the right side, upper side or lower side of Figure 1), the situation display area The arrangement of the multiple sub-areas of the area SDA along the direction away from (or close to) the display area DA may also be similar to the arrangement in FIG. 2 .

It should be noted first that the respective transmittances of the first sub-area Z1, the second sub-area Z2, the third sub-area Z3, the fourth sub-area Z4 and the fifth sub-area Z5 of the display area DA and the situation display area SDA are approximately the same. equal. Therefore, there is no need to set up an additional light-shielding structure at the junction of the display area DA and the contextual display area SDA to block the light leakage caused by the poor arrangement of the liquid crystal layer LCL at the edge of the display area DA and the arrangement of the sealant layer 150 and the circuit element layer 120. According to This improves the overall picture continuity between the display area DA and the situation display area SDA.

For example, in this embodiment, the first sub-area Z1 of the situational display area SDA is provided with a signal wiring layer 130, a sealant layer 150, a first light-shielding pattern 210 and a second polarizer POL2. The second sub-region Z2 is provided with a circuit element layer 120, a liquid crystal layer LCL, a second light-shielding pattern 220 and a second polarizer POL2. The third sub-region Z3 is provided with a pixel structure layer 110, a liquid crystal layer LCL, a third light-shielding pattern 230, a first color filter layer 260 and a second polarizer POL2.

It is particularly noted that in this embodiment, only the second substrate 200 extends to the fourth sub-area Z4 of the situation display area SDA. For example, the fourth sub-region Z4 may be provided with the fourth light-shielding pattern 240 but not the second polarizer POL2. However, the present invention is not limited to this. In another embodiment, the second polarizer POL2-A of the display device 10A may extend from the first sub-region Z1 into the fourth sub-region Z4.

On the other hand, the fifth sub-area Z5 and the display area DA each have substantially the same structural film layers, such as an optical brightness enhancement film 300, a first polarizer POL1, a pixel structure layer 110, a liquid crystal layer LCL, The third light shielding pattern 230, the first color filter layer 260 and the second polarizer POL2. The only difference is that the fifth sub-area Z5 of the situation display area SDA is provided with a first light panel 410, while the display area DA is provided with a second light panel 420.

Furthermore, in order to align the plurality of liquid crystal molecules (not shown) in the liquid crystal layer LCL in a specific direction without being affected by an electric field, the display device 10 may further include a first alignment layer AL1 and a second alignment layer AL2. In this embodiment, the first alignment layer AL1 and the second alignment layer AL2 are respectively disposed on the first substrate 100 and the second substrate 200, and the liquid crystal layer LCL is sandwiched between the first alignment layer AL1 and the second alignment layer AL2. between.

That is to say, the first alignment layer AL1 and the second alignment layer AL2 are also provided in the second sub-area Z2, the third sub-area Z3, the fifth sub-area Z5 and the display area DA of the context display area SDA.

Since the configurations of the structural films in each of the above areas are different, in order to make the transmittance of each of these sub-regions close to the transmittance of the display area DA, even the transmittance of the same structural film in different areas can be differentiated. . For example, in the situation display area SDA, the fourth sub-area Z4 has significantly fewer structural film layers than the fifth sub-area Z5. Under the illumination of the same first light panel 410, in order to balance the transmittance of the fourth sub-region Z4 and the fifth sub-region Z5, the aperture ratio of the fourth light-shielding pattern 240 located in the fourth sub-region Z4 must be significantly lower. The aperture ratio of the third light-shielding pattern 230 in the fifth sub-region Z5. The aperture ratio here is, for example, the percentage of the opening area of the portion of the light-shielding pattern located in the sub-region to the overall distribution area of the portion of the light-shielding pattern.

FIG. 4 is a schematic cross-sectional view of a display device according to a third embodiment of the present invention. Please refer to FIG. 4 . The only difference between the display device 10B of this embodiment and the display device 10 of FIG. 2 is that the distribution configuration of the first polarizer and the second polarizer is different. Specifically, compared with the first polarizer POL1 in FIG. 2 , the first polarizer POL1 -B of the display device 10B of this embodiment further extends from the fifth sub-region Z5 to the third sub-region Z3 and the second sub-region Z2 and the first sub-area Z1.

On the contrary, compared with the second polarizer POL2 in FIG. 2 , the second polarizer POL2-B of the display device 10B does not extend from the fifth sub-region Z5 to the edge of the second substrate 200 to the first sub-region Z1 and the second polarizer POL2-B of the display device 10B. The second sub-area Z2, the third sub-area Z3 and the fourth sub-area Z4.

Based on the contents disclosed in Figures 2 and 4, it can be seen that the first sub-area Z1, the second sub-area Z2 and the third sub-area Z3 of the situational display area SDA each have one polarizer, and the fifth sub-area Z5 and the display The number of polarizers provided in each area DA is two.

FIG. 5 is a schematic cross-sectional view of a display device according to a fourth embodiment of the present invention. Please refer to FIG. 5 . The only difference between the display device 10C of this embodiment and the display device 10B of FIG. 4 is that the configuration of the optical brightness enhancing film is different. Specifically, compared with the optical brightness enhancement film 300 of FIG. 4 , the optical brightness enhancement film 300B of this embodiment also extends from the display area DA and the fifth sub-area Z5 toward the edge of the first substrate 100 to the first sub-area Z1 , the second sub-area Z2 and the third sub-area Z3.

It is particularly important to note that since the third sub-region Z3 of this embodiment is also provided with an optical brightness enhancement film 300B, in order to reduce the transmittance difference between the third sub-region Z3 and the display area DA (or the fifth sub-region Z5), the The aperture ratio of the three light-shielding patterns 230A in the third sub-region Z3 can be adjusted to be smaller than the aperture ratio of the third light-shielding pattern 230A in the display area DA. For example, in this embodiment, the third light-shielding pattern 230A on the second substrate 200A has a plurality of first openings OP1 located in the display area DA and a plurality of second openings located in the third sub-area Z3. OP2. The first opening OP1 and the second opening OP2 respectively have a first width W1 and a second width W2 along the direction D1, and the first width W1 of the first opening OP1 is greater than the second width W2 of the second opening OP2.

However, the present invention is not limited to this. In other embodiments, the relative size relationship of the opening widths of the light-shielding pattern in different areas can be adjusted based on the differences in the arrangement of the structural film layers in the respective areas (such as differences in number and film layer transmittance).

FIG. 6 is a schematic cross-sectional view of a display device according to a fifth embodiment of the present invention. Referring to FIG. 6 , the difference between the display device 20 of this embodiment and the display device 10B of FIG. 4 mainly lies in the relative size relationship between the first substrate and the second substrate. Specifically, in this embodiment, the first substrate 100A of the display device 20 may protrude from the side edge of the second substrate 200B. That is, unlike the display device 10 of FIG. 1 , in this embodiment, the second length of the second substrate 200B along the direction D1 may be smaller than the first length of the first substrate 100A along the direction D1 .

Since the second substrate 200B of this embodiment does not extend to the fourth sub-area Z4 of the situation display area SDA, the fourth light-shielding pattern 240 of FIG. 4 is not disposed in the fourth sub-area Z4. Correspondingly, the first substrate 100A of this embodiment also extends from the first sub-region Z1 to the fourth sub-region Z4. Therefore, the first polarizer POL1-C can also extend from the first sub-region Z1 to the fourth sub-region Z4.

In this embodiment, the first substrate 100A may also be provided with a patterned metal layer 140 in the fourth sub-region Z4. Since the patterned metal layer 140 of this embodiment is not covered by the second substrate 200B, in order to reduce the reflectivity of the patterned metal layer 140 to the ambient light from the display side (ie, the upper side of FIG. 6 ), the patterned metal layer 140 may be Made of blackened metal with low reflectivity (such as blackened chromium or blackened nickel, but not limited to this).

However, the present invention is not limited to this. In order to meet different application requirements, the display device 20 may have a half mirror design in the fourth sub-region Z4. That is, the patterned metal layer 140 with multiple openings can also be made of other metals with a certain reflectivity (such as silver or aluminum).

FIG. 7 is a schematic cross-sectional view of a display device according to a sixth embodiment of the present invention. Please refer to FIG. 7 . The only difference between the display device 30 of this embodiment and the display device 10A of FIG. 3 is that the second substrate 200C of the display device 30 of this embodiment is also provided with a fourth sub-area Z4 of the situation display area SDA. The second color filter layer 270. For example, the second color filter layer 270 may include a plurality of first color filter patterns 271 , a plurality of second color filter patterns 272 and a plurality of third color filter patterns 273 . These color filter patterns may be respectively disposed in multiple openings of the fourth light shielding pattern 240A.

In particular, since the fourth sub-region Z4 is also provided with a second color filter layer 270 compared to the adjacent first sub-region Z1, in order to reduce the transmittance of the first sub-region Z1 and the fourth sub-region Z4 The difference is that the opening area of the fourth light-shielding pattern 240A is, for example, 3.7 times the opening area of the first light-shielding pattern 210, but is not limited thereto.

FIG. 8 is a schematic cross-sectional view of a display device according to a seventh embodiment of the present invention. Referring to FIG. 8 , the only difference between the display device 30A of this embodiment and the display device 30 of FIG. 7 is that the composition of the second color filter layer is different. Specifically, in this embodiment, the second color filter layer 270A on the second substrate 200D further includes a plurality of light-transmitting patterns 274. These light-transmitting patterns 274 are disposed in part of the openings of the fourth light-shielding pattern 240B, and are suitable for allowing multiple colors of light emitted by the first light panel 410 to pass through. Accordingly, the difference in aperture ratio between the first light-shielding pattern 210 in the first sub-region Z1 and the fourth light-shielding pattern 240B in the fourth sub-region Z4 can be reduced, which helps to balance the display device 30A in the first sub-region Z1 and the fourth sub-region Z4. The penetration rate of the fourth sub-zone Z4.

To sum up, in the display device according to an embodiment of the present invention, the display area and the three sub-areas of the context display area other than the display area are each provided with the same or different numbers and the same or different types of structural film layers. Through the combination of these structural film layers in the three sub-areas of the display area and the contextual display area, the transmittances of these areas are approximately equal. Therefore, there is no need to set up a light-shielding structure at the junction of the display area and the situational display area to block light leakage caused by poor arrangement of the liquid crystal layer, the setting of the sealant layer and the circuit structure, which helps to significantly improve the picture continuity between the display area and the situational display area. sex.
