Drawings
Fig. 1 is a schematic structural diagram of an electronic paper with a rounded display area angle according to an embodiment of the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, an embodiment of the present application provides an electronic paper with a rounded display area corner, a TFT screen 1 with a rounded display area corner, a rectangular electronic paper 2, a waterproof film 3 and a protective film 4; the space between the rectangular electronic paper 2 and the waterproof membrane 3 is filled with waterproof glue 5, and the rectangular electronic paper 2 is fixed above the TFT screen 1; the protective film 4 covers the waterproof film 3; the edge of the displayable area of the TFT screen 1 comprises four straight line edges and four circular arc edges, and the adjacent straight line edges are connected through one circular arc edge.
In this embodiment, the four corners of the display area of the TFT screen 1 are designed into 4 circular arc edges, and the space between the circular arc of the display area and the edge of the electronic paper is used as a reserved space to prepare for the subsequent addition of the silver colloid hole.
The principle of the low-temperature whitening phenomenon is that the edge of the electronic paper is dehydrated after being subjected to laser cutting and high-temperature curing in the process of manufacturing, and the whitening phenomenon is caused when the electronic paper module displays (except for a white picture) colors at four corners of a display area under the low-temperature condition due to the low activity of capsule particles in the electronic paper under the low-temperature condition. In this embodiment, the display area of the TFT is made into an arc shape, the rectangular electronic paper 2 is rectangular, and the phenomenon of whitening at four corners of the display area of the electronic paper is solved by using the large distances between the arc of the display area and the four corners of the rectangular electronic paper 2, because after the distance becomes large, the influence of the high-temperature curing process in the cutting and processing process of the rectangular electronic paper 2 on the display area of the rectangular electronic paper 2 is greatly reduced, thereby the problem of whitening at low temperature in the display area of the existing electronic module can be solved.
Illustratively, a silver colloid hole 20 exists in the space between the circular arc edge of the TFT screen 1 and the edge of the rectangular electronic paper 2; the distance between the center of the silver colloid hole 20 and the nearest straight line of the straight line edge of the TFT screen 1 is larger than a preset value.
In order to make the silver colloid hole 20, the existing electronic paper module needs to make two ears below the electronic paper to make the silver colloid hole 20, meanwhile, the problem of I C end cleaning can be influenced by overlong ears, the silver colloid hole 20 is made by utilizing the space between the circular arc edge of the display area of the TFT screen 1 and the edge of the rectangular electronic paper 2, and thus, the silver colloid hole 20 is designed without additionally adding ears below the rectangular electronic paper 2, so that the size of the rectangular electronic paper 2 is shorter than that of the original design under the condition that the display area of the module is as long, the typesetting utilization rate of the rectangular electronic paper 2 is increased, and the typesetting is increased as well as the PS film design principle. Thereby reducing costs.
The position of the silver colloid hole 20 is designed according to the size of the silver colloid hole 20 and the distance from the movable area of the glass, and the size of the silver colloid hole 20 is 1.7mm, and the distance from the movable area is more than or equal to 0.6mm. The glass movable region is understood to be the region occupied before the four corners of the display region of the TFT screen 1 are rounded.
Illustratively, the waterproof film 3 is a PS film for electronic paper display, and the surface layer of the PS film for electronic paper display is BARRI ER layers.
The PS film has the function of preventing water vapor, and a layer BARRI ER is arranged on the PS film. In general, the design of PS films is extended outward by 1.2 to 1.5mm based on the outer shape of electronic paper.
The protective film 4 is exemplified by an AG film.
AG film, also called anti-glare protective film 4, fog protective film 4, frosted protective film 4, etc., is made by coating sand on the surface of the base material, and has the main function of preventing the upper light reflection of the screen, so that people can not generate the eye-shaking effect, and meanwhile, the AG film can also play roles of fingerprint prevention, scratch prevention, etc., and is commonly used for the surface protection of some computer screens.
Illustratively, the entire screen of the TFT screen 1 is a display area.
The display area and the touch area of the TFT screen 1 are sometimes overlapping areas, some areas can be displayed and touched, some intelligent products are designed to be partially overlapping, and the touch screen and the display screen are completely separated. The manufacturer of the TFT LCD can make clear marks on CAD drawings so that the manufacturer of the electronic paper designs the appearance according to the size of the area.
Compared with the prior art, the embodiment of the utility model provides the electronic paper with the arc display region angle, and compared with the prior electronic paper module, the electronic paper with the arc display region angle has the advantages that the arc display region angle of the TFT screen 1 is arc, the reserved space from the arc display region to the edge of the electronic paper is increased, and the reserved space is used for arranging the silver adhesive holes 20, so that the silver adhesive holes 20 are not required to be designed by additionally arranging ears under the electronic paper, and the size of the electronic paper is shorter than that of the prior electronic paper module design under the condition that the display region is not increased, and the typesetting utilization rate of the electronic paper is increased. Meanwhile, the distance from the arc of the displayable area to the edge of the electronic paper is increased, and the influence of the high-temperature curing process in the cutting and manufacturing process of the electronic paper on the display area of the electronic paper can be reduced.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the utility model, such changes and modifications are also intended to be within the scope of the utility model.
