At least one first spacer has a first height, and the height of each second spacer does not exceed the first height. Wherein, the first height is equal to the first distance.

Description
Technical Field
The present invention relates to a display panel, and more particularly, to a display panel capable of suppressing disturbance of liquid crystal molecules.
Background
In the conventional liquid crystal display panel, liquid crystal molecules are used to change the polarization direction of light emitted from a light source, so that the light can pass through the polarizing plates on both sides of the liquid crystal layer, thereby achieving the display effect. The liquid crystal molecules are liquid crystals in liquid and solid states, so that the liquid crystal molecules can have the flowing property of liquid and the optical property of crystalline solid.
In the process of fabricating the liquid crystal display panel, the conventional method is to use a spacer (spacer) to separate the thin film transistor array substrate and the color filter substrate to form a space between the two substrates, and liquid crystal molecules can be filled in the space by the conventional method.
Next, in order to obtain a good light transmittance, a liquid crystal display panel is generally manufactured using a glass substrate. However, when the glass substrate is used in a strong light environment, the glass substrate is easily reflected, which induces visual fatigue of the user and reduces the quality of appreciation.
Accordingly, in order to satisfy the trend of light and thin and solve the problem of light reflection of the glass substrate, it is a common practice to replace the glass substrate with a polymer material to reduce the weight and thickness of the display panel and effectively solve the problem of external light reflection of the glass substrate.
However, the polymer substrate is easily deformed by external force, compared to the glass substrate. When the polymer substrate is deformed by force, the liquid crystal molecules of the display panel are also squeezed to generate a flow phenomenon, thereby affecting the display quality. When the liquid crystal molecules are squeezed by an external force, the liquid crystal molecules at the stress point squeeze adjacent liquid crystal molecules, so that the liquid crystal molecules are pushed to generate disturbance and form a ripple phenomenon (namely, the display defect of the water ripple in the invention).
Further, the liquid crystal molecules have a specific viscosity due to the influence of the molecular structure. Therefore, when the liquid crystal molecules are disturbed, the displayed image is changed along with the fluctuation ripple flow, so that a user can easily perceive the disturbance of the liquid crystal molecules caused by external force, and the viewing quality is further reduced.
In view of the foregoing, it is desirable to provide a display panel to improve the defects of the conventional display panel.

Wherein, when M is 1, the 1 × N array represents that the array pixels are arranged along the longitudinal direction (the direction of parallel rows and columns, i.e. the first direction of the present invention); and when N is 1, the M × 1 array represents that the array pixels are arranged along the lateral direction (the direction parallel to the rows, i.e., the second direction according to the present invention).
The spacers are arranged continuously, which means that the spacers are arranged between adjacent pixel units. On the contrary, if at least some adjacent pixel units have no spacers, the spacers are not continuously arranged.
Referring to fig. 1a and fig. 1b, fig. 1a is a side view of a display panel according to an embodiment of the invention, and fig. 1b is a top view of a display panel according to another embodiment of the invention, the top view being viewed from one side of a tft array substrate.

Preferably, the height of each second spacer is less than the first height H1And is greater than or equal to the first height H1To make the liquid crystal molecules have good fluidity among each pixel unit, and still avoid the display defect of water ripple.
Please refer to fig. 1 b. In the display panel 100, the pixel units 160 are a 7 × 3 array of pixel units, wherein the 7 × 3 array represents a matrix array having 7 columns of pixels and 3 rows of pixels.

In the row 1 pixel unit, the second spacers 151, 152, 153, 154 and 155 are disposed between at least some adjacent pixel units 160 along the second direction 100 b.
In each row of pixel units, the second spacers 151, 152, 153, 154, 155, and 156 are arranged along the second direction 100b, and may be continuous or discontinuous. In each row of pixel units in the 1 st to 5 th columns, the second spacers 151, 152, 153, and 154 are continuously arranged along the second direction 100 b; in each row of pixel units in the 4 th to 7 th columns, the second spacers 154, 155 and 156 are not continuously arranged along the second direction 100 b. In the figure, the first spacers 140 are continuously arranged along the first direction 100a, but as long as the second spacers are configured to match with the first spacers, the second spacers 140 may also be discontinuously arranged (not shown), and are not limited.
In one embodiment, the second spacers 151 may be continuous spacers along the first direction 100a between the 1 st and 2 nd columns of pixel units. In the 2 nd and 3 rd columns of pixel units, the 3 rd and 4 th columns of pixel units, or the 4 th and 5 th columns of pixel units, the second spacers 152, 153, and 154 may be segmented (discontinuous) spacers along the first direction 100 a. The second spacers 153 may also be aligned with two adjacent pixel units 160 (i.e., along the first direction 100a, the length of the second spacers 153 is equal to the length of the pixel units 160). In another embodiment, one of the second spacers 151, 152, 153, and 154 and another one thereof may have different structural shapes.
Referring to fig. 1c, a side view of a second spacer according to an embodiment of the invention is shown. In one embodiment, the side view of the second spacer 150 can be as shown in fig. 1c for the embodiments (i) to (iv).

In the display panel of the present invention, the second spacers may include various shapes, other suitable shapes, or any mixture of the above shapes of the second spacers disclosed in the aforementioned (i) to (iv) embodiments.
Fig. 2 is a top view of a display panel according to another embodiment of the invention, as seen from a side of a tft array substrate. In an embodiment, the structure of the display panel 200 of fig. 2 is substantially the same as the structure of the display panel 100 of fig. 1b, and the difference between the two is that the second spacers 250 of the panel 200 have different arrangements.
Wherein, along the second direction 200b, in the pixel units of the 1 st row and the 3 rd row, the second spacers 250 are continuously arranged; in the pixel unit of the 2 nd row, the second spacers 250 are not arranged consecutively. Therefore, the second spacers 252 are not evenly distributed in the display panel 200.
As shown in fig. 2, when the display panel 200 has the first display area 201 (the 1 st row of pixels), the second display area 202 (the 2 nd row of pixels), and the third display area 203 (the 3 rd row of pixels) which are independent, the distribution density of the second spacers 250 in the first display area 201 is the same as the distribution density of the second spacers 250 in the third display area 203, but the distribution density of the second spacers 250 in the first display area 201 is different from the distribution density of the second spacers 250 in the second display area 202. In this embodiment, the distribution density of the second spacers 250 at the periphery of the display area is greater than the distribution density of the second spacers 250 at the center of the display area.
In one embodiment, the second spacers in the central region of the display panel may have a higher distribution density or be evenly distributed in the display panel according to the application requirements of the display panel (e.g., panel strength, degree of suppressing disturbance of liquid crystal, or others).
Fig. 3 is a partial top view of a display panel according to still another embodiment of the invention, as seen from a side of a tft array substrate. The local area structure of the display panel 300 in fig. 3 is a 3 × 3 array of pixel units 360, which is substantially the same as the structure of the display panel 100 in fig. 1b, and the difference between the two structures is that the arrangement of the second spacers 351 and 352 of the display panel 300 is different from the arrangement of the second spacers 151, 152, 153, 154, 155 and 156 of the display panel 100.
In the display panel 300, along the first direction 300a, the second spacers 351 are continuous spacers, that is, one second spacer 351 has a length that spans three pixel units 360, but the second spacers 352 are a plurality of discontinuous spacers. The second spacer 351 has a length L1. In the pixel units of the 1 st to 3 rd rows, the lengths of the second spacers 352 are L21、L22And L23。
Along the first direction 300a, the length L of the second spacer 351 is 100% based on the length L of the display region 301 of the display panel 3001Is greater than or equal to 50%, and the total length (L) of the second spacers 35221、L22And L23The sum of) is greater than or equal to 50%. Wherein, along the first direction 300a,the length L of the display region 301 is defined as the distance between a point 341 of the outermost edge of the uppermost first spacer 340 and a side 341 of the outermost edge of the lowermost pixel unit 360, and the width W of the display region is defined as the distance between a side 363 of the outermost edge of the rightmost pixel unit 360 and a side 365 of the outermost edge of the leftmost pixel unit 360 along the second direction 300 b. It should be noted that, the terms upper, lower, right and left are only used to describe the relative position relationship between the first spacer 340 and the pixel unit 360 in the top view.
If the total length of the second spacer is greater than or equal to 50%, the second spacer can also reduce the disturbance of the external force to the liquid crystal molecules, so as to suppress the display defect of the water ripple.
Fig. 4 is a partial top view of a display panel according to yet another embodiment of the invention, as seen from a side of a tft array substrate. In one embodiment, the structure of the display panel 400 is substantially the same as the structure of the display panel 100 of fig. 1B, and the difference between the two is that the pixel units of the display panel 400 are 7 × 5 array, and the pixel units of the display panel 400 include red pixels R, green pixels G, and blue pixels B.
In each row of pixel units, the red pixels R, the green pixels G and the blue pixels B are arranged in a staggered manner; and in each column of pixel units, the pixel units are pixels of the same color.
In the 1 st, 2 nd and 7 th columns of pixel units, the first spacers 440 are continuously arranged along the first direction 400 a; however, in the pixel units of the 3 rd to 6 th rows, the first spacers 440 are not continuously arranged along the first direction 400 a. In the row 1 pixel unit, the second spacers 450 are arranged continuously along the second direction 400 b; however, in the pixel units of the 2 nd to 5 th columns, the second spacers 450 are not continuously arranged along the second direction 400 b.
Fig. 5 is a partial top view of a display panel according to still another embodiment of the invention, as seen from a side of a tft array substrate. In an embodiment, the structure of the display panel 500 is substantially the same as that of the display panel 400, and the difference between the two is that the first spacers 540 and the second spacers 550 of the display panel 500 have different arrangements.
In the display panel 500, the first spacers 540 are disposed between at least some adjacent blue pixels B along the first direction 500a, and the first spacers 540 are continuously arranged. In one embodiment, the first spacers 540 may also be arranged discontinuously.
When the first spacers 540 are continuously arranged between the adjacent blue pixels B along the first direction 500a, although the first spacers 540 reduce the aperture ratio of the adjacent pixel units to reduce the brightness, only the proportion of the brightness of the blue pixels B in the overall brightness of the display panel 500 is small. Accordingly, when the first spacers 540 are continuously arranged between the adjacent blue pixels B along the first direction 500a, the influence on the brightness of the display panel 500 is very small, and the first spacers 540 can still effectively suppress the display defect of the moire.
In an embodiment, in order to effectively improve the water ripple suppression effect, a length of one of the second spacers may be elongated to be at least equal to or greater than lengths of two adjacent pixels. For example, if the length of the blue pixel B is PL, the length of a second spacer may be equal to or greater than 2 times PL, for example, the length of a second spacer may be 2PL plus the pitch length between two adjacent blue pixels B, or may be a multiple of PL. In this embodiment, the two second spacers can be connected by the bottom, integrally connected, other suitable connecting structure or any mixture thereof.
In another embodiment, the width of the second spacer may be less than or equal to the line width of the black matrix between two pixel units of the corresponding color filter substrate, so as to prevent the second spacer from degrading the display effect of the display panel.
It can be seen from the foregoing embodiments of the present invention that the second spacers of the display panel of the present invention can effectively reduce the disturbance of the liquid crystal molecules caused by the external force, and can suppress the display defect of the water ripple.
Secondly, when the height of the second spacer is greater than or equal to half of the distance between the thin film transistor array substrate and the color filter substrate (i.e. the first height of the first spacer), the second spacer can also reduce the phenomenon of liquid crystal molecule disturbance, thereby avoiding the existing defects of water ripple.
Moreover, according to the requirements and applications of the display panel, the second spacers can have different shapes, so as to effectively inhibit the disturbance of the liquid crystal molecules caused by external force. When the display panel is provided with the second spacers, the manufactured display panel has optimal mechanical strength and can resist external force, and then liquid crystal molecule disturbance generated by pressing the display panel by the external force is avoided.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
