This application claims the benefit and priority of Chinese Patent Application No. 201610006126.9, filed on Jan. 5, 2016. The entire disclosure of the above application is incorporated herein by reference.
The present disclosure relates to the field of display technology, and particularly, to a light guide plate and a fabricating method thereof, an array substrate and a fabricating method thereof, and a display device.
GIA (Gate driver In Array, i.e. a gate driving circuit fabricated in an array substrate) may implement a narrow frame design of a display panel, but since wiring is conducted inside pixel in such an array substrate, the pixel aperture ratio is reduced, thereby reducing pixel transmissivity. This structural configuration makes the luminance of a display region on the array substrate for arranging the gate driven circuit decrease, thus forming bright streaks at a junction region between the display region and a peripheral display region.
The embodiments described herein provide a light guide plate and a fabricating method thereof, an array substrate and a fabricating method thereof, and a display device, which can remove bright streaks at a junction region between a display region for arranging a gate driving circuit and a peripheral display region.

To more clearly understand the present disclosure, the present disclosure will be described below in further detail in conjunction with the accompanying drawings and the specific embodiments. It should be noted that, in the absence of conflict, embodiments of the present application and features in the embodiments may be combined with each other.
Embodiment 1 of the present disclosure provides a light guide plate. As shown in
“a first region A” described herein is a region corresponding to a first display region A′ of an array substrate 200 when the light guide plate body 110 is applied to a display device, and “a first display region A”' described herein is a region where a gate driven circuit is fabricated in a pixel unit on the array substrate; “a second region B”' described herein is the region other than the first region A, and “a second display region B”' described herein is the region other than the first display region A′.
In the present embodiment, since the density of net-dots 120 in the first region A is greater than the density of net-dots 120 in the second region B, the light guiding capability of the light guide plate 110 in the first region A is stronger, so that more light is incident on the first display region A′ of the array substrate 200, whereby it is possible to enhance the display luminance of the first display region A′, reduce the difference between the display luminance of the first display region A′ and the display luminance of the second display region B′, and weaken the luminance difference line.
In specific applications, the present disclosure does not define specific values of the density of net-dots 120 within the first region A and of the density of net-dots in the second region B. According to the description of embodiments of the present disclosure, those skilled in the art may reasonably design the density of net-dots in the first region A and the density of net-dots within the second region B, so that the display luminance of the first display region A′ and of the second display region B′ are more uniform.
Referring to
On the basis of Embodiment I above-described, as an alternative embodiment, the density of net-dots within the second sub-region B2 may be gradually increased from the first region A to the first sub-region B1, so that the luminance of the second display sub-region B2′ can be gradually increased from the first display region A′ to the first display sub-region B1′, to further reduce the luminance difference.
Embodiment II of the present disclosure provides a light guide plate. As shown in
“a first region A” described herein is a region corresponding to a first display region A′ of an array substrate 200 when the light guide plate body 110 is applied to a display device, and “a first display region A′” described herein is a region where a gate driven circuit is fabricated in a pixel unit on the array substrate 200; “a second region B” described herein is the region other than the first region A, corresponding to the second display region B′, and “a second display region B′” described herein is the region other than the first display region A′.
In the present embodiment, since the diameter of net-dots 120 in the first region A is greater than the density of net-dots 120 in the second region B, the light guiding capability of the light guide plate 110 in the first region A is stronger, so that more light is incident on the first display region A′ of the array substrate 200, whereby it is possible to enhance the display luminance of the first display region A′, reduce the difference between the display luminance of the first display region A′ and the display luminance of the second display region B′, and weaken the luminance difference line.
In specific applications, in the present embodiment, the diameter of net-dots of the second region B may be 25-35 μm, and the diameter of net-dots of the first region A is 30-50 μm.
Referring to
On the basis of Embodiment II above-described, as an alternative embodiment, the diameter of net-dots within the second sub-region B2 may be gradually increased from the first region A to the first sub-region B1, so that the luminance of the second display sub-region B2′ can be gradually increased from the first display region A′ to the first display sub-region B1′, to further reduce the luminance difference and weaken the luminance difference line.
Specifically, when the second region B above-described comprises a first sub-region B1 and a second sub-region B2 in accordance with the above-described alternative manner, the diameter of net-dots within the second sub-region B2 may be gradually increased in the direction of the first region A toward the first sub-region B1 from 30-35 μm to 45-50 μm until to be consistent with the diameter of net-dots within the first sub-region B1.
It should be noted that in the embodiments described herein, the first region A corresponds to the first display region A′, but it does not mean that the location, area and contour of the first region A is completely identical with the location, area and contour of the first display region A′. In actual practice, due to the divergence of light, the area of the first display region A′ can be slightly larger than the area of the first region A. Similarly, it is also true for the relationship between the first sub-region B1 and the first display sub-region B1′.
Embodiment III of the present disclosure provides an array substrate. In this embodiment, the array substrate is a GIA array substrate. Referring to
Such configuration manner makes the area of the pixel electrode of the second display sub-region B2′ to be less than the area of the pixel electrode P of the first display sub-region B1′. This can make the display luminance of the second display sub-region B2′ lower than the display luminance of the first display sub-region B1′, so that the display luminance of the second display sub-region B2′ is between the first display region A′ and the first display sub-region B1′, to form a transition zone of luminance and weaken the luminance difference line.
In an alternative embodiment of the present disclosure, the length of the pixel electrodes P within the second display sub-region B2′ in the column direction is gradually increased from the first display region A′ toward the first display sub-region B1′.
This can make the area of the pixel electrodes P of the second display sub-region B2′ be gradually increased from the first display region A′ to the first display sub-region B1′, thereby making the display luminance of the second display sub-region B2′ be gradually increased from the first a display region A′ toward the first display sub-region B1′, to further reduce the luminance difference and weaken the luminance difference line. Of course, in terms of the meeting of the basic purposes of the present disclosure, the embodiments are not necessarily performed in this way.
It is not difficult to understand that, although in the embodiments described herein, the areas of different pixel electrodes are made different in such a manner that the length of the pixel electrodes is different in the column direction but the same in the row direction, whereas in practical applications, in some other alternative embodiments, it also may be specified that the length of the pixel electrodes may be the same in the column direction but different in the row direction; or the area of the pixel electrodes may be made different in another manner. As long as the area of a pixel electrode within the first display sub-region B2′ is less than the area of a pixel electrode within the first display sub-region B1′, the luminance difference line can be weakened to a certain extent; and as long as the area of the pixel electrodes within the first display sub-region B1′ is gradually increased from the first display region A′ to the first display sub-region B1′, an effect of the luminance difference line being further weakened can be achieved, and the corresponding embodiments should fall within the scope of protection of the present disclosure.
In any of the above-described embodiments, the length of the first display region A1 in the row direction may be between 0.8-1.2 mm. Further, the length of the first display region in the row direction may be between 0.95-1.05 mm, and may specifically be 1 mm.
