In the existing display panel, a vacuum medium is arranged in a blind hole area of a light-emitting layer, a non-vacuum medium is arranged in TFT glass and packaging glass, light energy loss is large when light passes through the packaging glass, the blind hole area and the TFT glass, the transmittance is low, in order to improve the transmittance, the blind hole area cannot be modeled, a supporting column cannot be placed, interference phenomenon can be generated near the blind hole area, Newton rings are formed, and therefore the imaging effect is poor.
In order to solve the problem that exists among the present display panel, the utility model provides a display panel, see fig. 1, this display panel includes TFT glass 1, luminescent layer 2, envelopment glass 3, polaroid 4, optical cement layer 5 and glass apron 6.
The light-emitting layer 2 includes a package region 201, a light-emitting region 203, a blind via region 202, and the like. An encapsulation region 201 may be located at an edge of the light emitting layer 2 for encapsulating the light emitting layer 2, and the encapsulation region 201 may be encapsulated by Frit (glass Frit). The material in the light emitting region 203 may be OLED, AMOLED, etc., and the present invention does not specifically limit the material of the light emitting region 203. The blind hole area 202 corresponds to the position of a camera in the display device and is used for the camera to acquire an external image. The blind hole area 202 is filled with a support 204, and the support 204 may be UV glue, optical glue, glass glue, or the like.
The utility model provides a display panel through pack the supporter in the blind hole region, can reduce the blind hole region and TFT glass board and encapsulate the refractive index difference between the glass to increase the transmissivity, improve the formation of image effect of camera.
In another embodiment of the present invention, the blind hole region 202 may be located at any position of the light emitting layer 2, for example, at the edge of the light emitting layer 2, or inside the light emitting layer 2. The number of the blind hole areas 202 is at least one, and each blind hole area 202 corresponds to the position of one camera.
In another embodiment of the present invention, the height of the support 204 in the blind hole region 202 matches the height of the filler in the package region 201 and the height of the support pillars in the light emitting region 203. Specifically, the following can be classified:
in the first case, when the height of the filler in the package region is different from that of the support pillars in the light emitting region, the height of the filler 204 in the blind hole region 202 may be the same as that of the filler in the package region 201 or the same as that of the support pillars in the light emitting region 203.
In the second case, when the height of the filler in the package region is the same as that of the support pillars in the light-emitting region, the height of the filler 204 in the blind hole region 202 is the same as that of the filler in the package region 201 and that of the support pillars in the light-emitting region 203.
During the manufacturing process, the height of the support 204 in the blind hole region 202 can be determined by the initial filling height of the support and the curing time, and when the initial filling height is determined, the shorter the curing time is, the larger the difference between the height of the cured support and the initial filling height is; the longer the curing time, the smaller the difference between the height of the cured support and the initial fill height. By optimizing the curing time when the initial fill level is determined, the height of the support can be made to meet the requirements.
According to the embodiment of the disclosure, the height of the support in the blind hole area is controlled, so that the height difference between the inside and the outside of the blind hole area is reduced, the interference phenomenon near the blind hole area is reduced or eliminated, Newton's rings are avoided to be formed, and the imaging effect of the camera is improved.
In another embodiment of the present disclosure, the difference between the refractive index of the support 204 in the blind hole region 202 and the refractive index of the TFT glass 1 is less than a preset value, such as but not limited to 0.05, and the difference between the refractive index of the support 204 and the refractive index of the encapsulation glass 3 is less than a preset value, such as but not limited to 0.05. Because the difference between the refractive index of the support 204 in the blind hole region 202, the refractive index of the TFT glass 1 and the refractive index of the encapsulation glass 3 is small, when light enters the camera through the encapsulation glass 3, the blind hole region 202 and the TFT glass 1, the deflection amount of the light can be reduced, the transmittance is increased, the light entering amount of the camera is increased, and the imaging effect of the camera is improved.
In another embodiment of the present disclosure, the refractive index of the support 204 in the blind via region 202 is greater than 1.7, and typically, the refractive index of the TFT glass 1 and the encapsulation glass 3 is less than 1.7, so that the support 204 in the blind via region 202 is greater than the refractive index of the TFT glass 1 and the encapsulation glass 3. Because the refractive index of the support 204 in the blind hole region 202 is higher than that of the TFT glass 1 and the encapsulation glass 3, when light enters the camera through the encapsulation glass 3, the blind hole region 202 and the TFT glass 1, the light is greatly deflected, so that light with a small viewing angle can enter the camera, thereby reducing the window of the camera and reducing the aperture of the blind hole region.
For example, FIG. 3The optical path diagram is shown with the diameter of the blind hole region t before the support is filled in the blind hole region. After filling the support material in the blind hole region, the incident angle is theta for the incident light1Angle of refraction theta2The refractive index of the filled support is
Setting the height of the filler in the blind hole region as h, the reduced aperture s of the blind hole region is h (tan theta)1-tanθ2)。
When the blind hole area in the display panel is filled, local dispensing can be carried out by using dispensing equipment, the TFT glass and the encapsulation glass are combined, and then the dispensing area is cured.
Taking the support as UV glue as an example, the specific filling process can be seen in fig. 4:
firstly, cleaning the TFT glass, and carrying out pretreatment, evaporation and laser ablation on the cleaned TFT glass.
And secondly, cleaning the encapsulation glass, performing frit dispensing and burning on the cleaned encapsulation glass, performing edge UV dispensing, and performing UV dispensing on the HIAA (namely the blind hole region).
And thirdly, combining the treated TFT glass with the treated encapsulation glass to obtain the VAS component.
And fourthly, carrying out edge UV curing treatment on the VAS assembly, then carrying out panel laser sealing, carrying out UV curing treatment on the HIAA, and then carrying out panel cutting.
An embodiment of the present invention provides a display device, which includes a display panel, and the display panel can be the display panel shown in fig. 2. In practical application, the display device can be a smart phone, a tablet computer, a smart television and other equipment with a display screen.
