20150124179
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Nov. 4, 2013 in the Korean Intellectual Property Office and assigned Serial number 10-2013-0133012, the entire disclosure of which is hereby incorporated by reference.
The present disclosure relates to a display device including a display screen protecting window and a method of manufacturing the same.
In general, a window is installed to protect a screen of a display device, such as a Liquid Crystal Display (LCD), which is used in a portable communication device, a Portable Multimedia Player (PMP), a Personal Digital Assistant (PDA), an MP3 player, or a Television (TV), and is also called a window part. In addition to a main object to protect a screen of a display device, the window is used for advertising and promotion of a manufacturer by printing various emblems, logos, letters, or patterns on a surface of the screen.
In recent years, due to rapid development of multimedia technologies and display technologies, there has been a revolution in display devices of a portable communication devices and a touch screen panel has been increasingly adopted in portable communication devices. Because a resistive touch sensor according to the related art uses two sensors to provide location information with a touch pressure, a film is attached to an upper end of a window provided in a portable communication device. However, a capacitive Touch Screen Panel (TSP), which is has been more widely used recently, informs a user of location information of a point at which electric charges are discharged when a touch occurs.
Referring to
The pattern film layer 3 includes a film layer (PET film) 3a, a deposition layer 3b having a pattern on a surface thereof, a color printing layer 3c provided on a rear surface of the deposition layer 3b, and a shielding layer 3d provided on a rear surface of the color printing layer 3c. A Ultra-Violet (UV) molding 6 is provided between the film layer 3a and the deposition layer 3b such that the deposition layer 3b may be attached to a rear surface of the film layer 3a.
However, because the display device including a window according to the related art is manufactured by combining a pattern film layer with a window, the price of the product increases due to the pattern film layer whose manufacturing process is complex, and the pattern film layer may be wetted and floated due to fine bubbles or an external appearance of the pattern film layer may become unattractive.
In addition, by combining the pattern film layer with the window formed of tempered glass, permeability of the product may be lowered. Further, because a color of the product may be realized by attaching a color printing layer on a rear surface of the pattern film layer with a deposition layer, a color deviation of the product may occur.
For example, as shown in
Further, because the pattern film layer is combined with the window at a high temperature according to the related art, the pattern film layer is laterally changed, contracted, and deformed.
In addition, because a hybrid cover glass integrated (G1F) TSP and a cover glass integrated (G2) TSP correspond to a method of depositing a one-layered Indium Tin Oxide (ITO) pattern film on a rear surface of a window to pattern the ITO pattern film, and attaching a sheet of ITO pattern film forming the remaining axis, realizing a pattern on a rear surface of the window is difficult and a pattern film layer cannot be applied to various types of touch screen panels.
Further, issues regarding heat emission are constantly troubling as increasing amounts of heat are transferred from the interior of the electronic product to the window.
Accordingly, an apparatus and manufacturing process by which a display device can be manufactured without using a pattern film layer according to the related art are desired to overcome the problems and disadvantages.
The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

The display part 14 may be any one of a Liquid Crystal Display (LCD) 14b including a touch screen panel 14a and an LCD 14b without the touch screen panel 14a. According to various embodiments of the present disclosure, the LCD 14b including the touch screen panel 14a will be described as an example.
The touch screen panel 14a may be any one of a film electrode type (GFF) Touch Screen Panel (TSP), a hybrid cover glass integrated (G1F) TSP, a cover glass integrated (G2) TSP, an On-Cell Touch Active Matrix Organic Light Emitting Diode (AMOLED) (OCTA) TSP, and/or the like.
The film electrode type (GFF) TSP corresponds to a method of attaching two sheets of Indium Tin Oxide (ITO) patterns to a window part for the X and Y axis of a touch screen panel for recognizing a contact location of a finger.
The hybrid cover glass integrated (G1F) TSP corresponds to a method of depositing a one-layered ITO pattern film on a rear surface of a window part (e.g., at a temperature of 230 degrees or higher), patterning the ITO pattern film, and attaching one sheet of ITO pattern film to form the remaining axis.
The cover glass integrated (G2) TSP corresponds to a method of depositing a two-layered X and Y axis ITO pattern film on a rear surface of a window to realize a touch sensor (e.g., deposited at a high temperature of 230 degrees or higher).
The OCTA corresponds to a method of directly depositing an ITO pattern film on an active organic diode based display (AMOLED) along the X and Y axes to realize a touch sensor.
Although the touch screen panels 14a disclosed earlier will be described as an example in the embodiment of the present disclosure, various embodiments of the present disclosure are not limited thereto. For example, a touch screen panel 14a having another configuration may be applied.
According to the embodiment of the present disclosure, among the above-described touch screen panels 14a, the cover glass integrated (G2) TSP 14a will be described as an example.
In this way, by forming a three-dimensional pattern 11a on a front surface of the window part 11 through etching instead of forming a pattern film layer 3 according to the related art (see
According to various embodiments of the present disclosure, three-dimensional pattern 11a may have a saw-tooth shape having ridges and furrows and a zigzag pattern, and/or the like. Of course, other shapes and patterns may be applied as the three-dimensional pattern 11a in addition to the disclosed shapes and patterns.
In this way, because the window according to the related art (see
Thus, according to various the embodiments of the present disclosure, by forming the three-dimensional pattern 11a having a saw-tooth shape and a zigzag, pattern, and/or the like instead of a linear plane on a front surface of the window part 11, heat may be easily emitted, dissipated, and radiated from a product due to a wide surface section and accordingly a heat emission problem of the product can be improved.
It can be seen from a general heat transfer equation of heat emission (Q)=Heat transfer coefficient (H)*Area (A)*dt (temperature difference) that an increase in a cross-section of a product may improve heat emission and lower a temperature of the product.
For example, a surface of the window part 11 may have an isosceles triangle three-dimensional pattern 11a to widen the surface of the window part 11 due to the two areas of the triangle. For example, when a surface of the window according to the related art (see
As described above, the window part 11 may be formed of tempered glass. Materials other than tempered glass may be applicable as the material of the window part 11. For example, the material of the window part 11 may be reinforced plastic, reinforced acryl, polycarbonate, and/or the like.
Referring to
At operation S1, a window part 11 having a three-dimensional pattern on the front surface thereof is formed. For example, the three-dimensional pattern 11a is formed on a front surface of the window part 11 through etching instead of a pattern film layer according to the related art.
According to various embodiments of the present disclosure, the three-dimensional pattern 11a may have a saw-tooth shape having ridges and furrows and a zigzag pattern, and/or the like. For example, a surface of the window part 11 may have an isosceles triangle three-dimensional pattern 11a to widen the surface of the window part 11 due to the two areas of the triangle, making emission of heat of the product possible (or otherwise improved in relation to the related art). For example, because a surface of a window according to the related art is simply linear, the surface of the window cannot be formed widely and thus heat cannot be easily emitted from the product.
At operation S1, a color printing layer 12 is formed. The color printing layer 12 is formed on a rear surface of the window part 11 having the three-dimensional pattern 11a.
At operation S2, a shielding printing layer 13 is formed. The shielding printing layer 13 is formed on a rear surface of the printing layer 12.
At S4 a display part 14 is formed. A touch screen panel 14a of a display part 14 is formed on a rear surface of the shielding printing layer 13.
The display part 14 is formed of an LCD 14b including a touch screen panel 14a, and the touch screen panel 14a may be any one of a film electrode type (GFF) TSP, a hybrid cover glass integrated (G1F) TSP, a cover glass integrated (G2) TSP, an OCTA touch screen panel, and/or the like.
The cover glass integrated (G2) TSP corresponds to a method of depositing a two-layered X and Y axis ITO pattern film on a rear surface of a window at a high temperature of 230 degrees or higher to realize a touch.
For example, because the window part 11 and the touch screen panel 14a are attached to each other at a high temperature in the cover glass integrated (G2) TSP, a pattern film layer 3 according to the related art (see
Because there is no such pattern film layer 3 according to the related art in the embodiment of the present disclosure, the above-mentioned disadvantages do not occur when the window part 11 and the touch screen panel 14a are attached to each other at a high temperature. Thus, the embodiment of the present disclosure may be applied to various types of touch screen panels 14a.

The cover glass integrated (G2) TSP corresponds to a method of depositing a two-layered X and Y axis ITO pattern film on a rear surface of a window at a high temperature of 230 degrees or higher to realize a touch.
For example, because the window part 21 and the touch screen panel 25a are attached to each other at a high temperature in the cover glass integrated (G2) TSP, a pattern film layer 3 according to the related art is transversely changed, contracted, and short-circuited due to high temperature heat and a shape thereof is changed.
Because there is no such pattern film layer 3 according to the related art in the embodiment of the present disclosure, the above-mentioned disadvantages caused by a high temperature do not occur when the window part 21 and the touch screen panel 25a are attached to each other at a high temperature. Thus, the embodiment of the present disclosure may be applied to various types of touch screen panels 25a.

The display part 54 is formed of an LCD 25b including a touch screen panel 54a, and the touch screen panel 54a may be any one of a film electrode type (GFF) TSP, a hybrid cover glass integrated (G1F) TSP, a cover glass integrated (G2) TSP, an OCTA touch screen panel, and/or the like.
Because the window part 51 and the touch screen panel 54a are attached to each other at a high temperature in the cover glass integrated (G2) TSP, a pattern film layer 3 according to the related art (see
Because there is no such pattern film layer 3 according to the related art in the embodiment of the present disclosure, the above-mentioned disadvantages caused by high temperature heat do not occur when the window part 51 and the touch screen panel 54a are attached to each other at a high temperature. Thus, the embodiment of the present disclosure may be applied to various types of touch screen panels 54a.
Hereinafter, a display device according to a sixth embodiment of the present disclosure will be described with reference to
Referring to
As illustrated in
The display part 64 may be any one of an LCD 64b including a touch screen panel 64a and an LCD 64b without the touch screen panel 64a. The LCD 64b including the touch screen panel 64a according to an embodiment of the present disclosure will be described as an example.
Because detailed operations of the disclosed touch screen panels 64a are the same as those of the first embodiment of the present disclosure, a description thereof will be omitted.
In this way, by forming a three-dimensional pattern 61a on front and rear surfaces of the window part 61 instead of forming a pattern film layer according to the related art, a depth and a three-dimensional feeling of a product may be realized, an external design of the product may become appealing, manufacturing costs of the product may be reduced, the thickness of the product can be reduced, and a manufacturing process of the product may be simplified and processing time may be reduced as a separate pattern film layer attaching process according to the related art is not necessary.
A color printing layer 62 may be directly attached to the three-dimensional pattern 61a formed on a rear surface of the window part 61 without using a deposition layer separately.
According to various embodiments of the present disclosure, three-dimensional pattern 61a may have a saw-tooth shape having ridges and furrows and a zigzag pattern, and/or the like. Of course, other shapes and patterns may be applied as the three-dimensional pattern 61a in addition to the disclosed shapes and patterns.
Referring to
At operation S131, a window part having three-dimensional patterns 61a formed on a front surface and a rear surface thereof is formed. The three-dimensional patterns 61a are formed on both the front and rear surfaces of the window part 61 through etching.
For example, the three-dimensional patterns 61a are formed instead of the pattern film layer according to the related art. Thus, because the pattern film layer according to the related art is not necessary, a manufacturing process for a product can be simplified, and manufacturing costs and a process time can be reduced.
According to various embodiments of the present disclosure, the three-dimensional pattern 61a has a saw-tooth shape having ridges and furrows and a zigzag pattern, and/or the like.
At operation S132, a color printing layer 62 is formed. The color printing layer 62 is formed on a rear surface of the window part 61 having the three-dimensional pattern 61a without using a separate deposition layer.
