Detailed description of the invention
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Fig. 1 is the schematic diagram of the main apparent direction of display screen module in correlation technique, and as shown in Figure 1, in the related, the bottom of screen of a lot of mobile device is provided with virtual key, and user, by touching these virtual keys, can perform corresponding controlling functions.Design feature in conjunction with mobile device: the front end of mobile device is display screen module, the top of this display screen module is panel construction, or claims face glass; Face glass itself is transparent, after such as the mode counter plate glass back such as serigraphy processes, can obtain the visible virtual key in front.
Simultaneously, different colours is rendered as in order to make mobile device itself, and in order to below counter plate glass, territory, the effective display area (AA of display screen module, Active Area) outside other mobile device parts carry out the reason such as blocking, also need to form ink layer by modes such as such as serigraphys at face glass back.
Therefore, wish the printing operation in conjunction with above-mentioned two kinds of objects in correlation technique, thus in a screen printing operation, realize simultaneously: retain the void region that virtual key and territory, effective display area etc. are corresponding, and at other region printing-inks.Than as shown in Figure 2, first obtain ground floor ink in the serigraphy of face glass back, and this ground floor ink remains the first void region corresponding to virtual key.
But because face glass is transparent, then in Fig. 2, the color relation of ground floor ink is the front end color of the mobile device that user finally sees.So, if the front end color of final required mobile device is light color, then the color of ground floor ink is light color.But, if the color of ground floor ink is too shallow, namely color gray value is lower than default gray value, appointed thickness (the ink thickness preset will be caused, avoid excessive increase plate thickness by controlling ink thickness) ground floor ink cannot the light such as the backlight of mobile device inside effectively be blocked, thus cause panel leakage problem.
In order to avoid causing leakage problem, in correlation technique on the basis of the above-mentioned ground floor ink of printing, also need at least to print one deck black ink, namely the second layer ink shown in Fig. 2, thus can either guarantee that the front end color of mobile device is constant, good shaded effect can be realized by black ink again.Meanwhile, with ground floor ink similarly, also there is the second void region corresponding to virtual key in second layer ink.
But, the ink of different colours is when performing serigraphy, certain making tolerance is there is between the silk screen adopted, and also there is certain position error etc. between each printing operation, these errors cannot be avoided in actual production process, and cause the first void region as shown in Figure 2, the second void region etc. to overlap completely the most at last, make the virtual key that obtains as shown in Figure 3, namely repeatedly the virtual key of serigraphy is overlapped in edge, staggered.
So, for the mobile device adopting correlation technique to produce, when being positioned at the backlight below virtual key and lighting, be there is multi shadow in the edge causing backlight at virtual key, also known as " double-edged eyelid " phenomenon.Certainly, in order to avoid " double-edged eyelid " phenomenon, the solution that backlight is not set below virtual key is have selected in correlation technique, this reduces science and technology sense and the aesthetics of mobile device on the one hand, be not easy to user's operation to virtual key under dark surrounds on the other hand, seriously reduce Consumer's Experience.
Therefore, the disclosure by improving the treatment process of display screen module, to solve the above-mentioned technical problem existed in correlation technique.
Fig. 4 is the flow chart of the treatment process of a kind of display screen module according to an exemplary embodiment, and as shown in Figure 4, this treatment process can comprise the following steps:
In step 402, repeatedly serigraphy process is carried out to the panel construction of display screen module, obtain the ink layer being positioned at described panel construction back, and the printing zone of described ink layer covers the default virtual key region on described display screen module.
In the present embodiment, be different from the correlation technique shown in Fig. 2, the disclosure without the need to retaining the void region corresponding to and preset virtual key in screen printing process, and covering printing is carried out in default virtual key region that can be directly corresponding to default virtual key, thus positioning precision demand when not only reducing serigraphy, and without the need to considering the registration problem between multiple void region that repeatedly serigraphy is formed, contribute to reducing the overall difficulty of screen printing operation, promoting the treatment effeciency of serigraphy.
In step 404, laser engraving process is carried out to described panel construction, make ink layer described in laser penetration, and form default virtual key corresponding to described default virtual key region place on described panel construction.
In the present embodiment, by increasing the processing procedure of laser engraving, to make in the formation of default virtual key and step 402, to disassociation between the serigraphy process in other regions, to reduce disposed of in its entirety difficulty.Simultaneously, by laser engraving process, the neat in edge degree of default virtual key and serigraphy number of times or the ink number of plies are had nothing to do, how many layers of ink no matter are printed in advance, all can carry out disposable formation by laser engraving process and preset virtual key, then this default virtual key must have neat edge, can not occur " double-edged eyelid " phenomenon under the irradiation of backlight.
Below the variety of processes in above-described embodiment is described further:
1, serigraphy process
Serigraphy process can comprise two processes:
1) according to the intended display color of panel construction, adopt the printing zone at the ink counter plate structure back of this intended display color to carry out serigraphy process at least one times, and obtain corresponding at least one deck displaying ink layer.
Than as shown in Figure 5, when only performing a serigraphy process, ground floor ink can be obtained.Because face glass back is close to by ground floor ink, then user directly can observe the color of ground floor ink from mobile device front end, i.e. intended display color.According to the color demand to mobile device pre-set, this intended display color can be determined.
When intended display color is light color, need to continue to perform following process 2).Wherein, " light color " can be understood as: the gray value of intended display color lower than default gray value, make only by the ink printing of this intended display color of appointed thickness when the facial glass back, panel leakage problem can be caused.For example, intended display color can be white.
2) according to the shading color preset, adopt the printing zone at the ink counter plate structure back of this shading color to carry out serigraphy process at least one times, and obtain being stacked at least one deck black-out ink layer of showing above ink layer.
Than as shown in Figure 5, adopt after the ink of shading color performs a serigraphy, the second layer ink be stacked in above ground floor ink can be obtained; Wherein, ground floor ink is used for presenting intended display color to user, and second layer ink is used for panel shading, avoids occurring panel leakage problem.Certainly, the gray value of shading color should be greater than above-mentioned default gray value, make only by the ink printing of this intended display color of appointed thickness when the facial glass back, panel leakage problem can not be caused.For example, this shading color can be black.
After above-mentioned serigraphy process, when user observes from the front (below of the face glass namely shown in Fig. 5) of face glass, as shown in Figure 6, user directly can see the intended display color of ground floor ink, and can not see the shading color of second layer ink.Meanwhile, during due to above-mentioned serigraphy process, the default virtual key region corresponding to default virtual key covers, and thus can not see any vestige about default virtual key in Fig. 6 equally.
Certainly, in serigraphy processing procedure, for avoiding shading color through the ground floor ink shown in Fig. 5, strengthening the reasons such as intended display color, the ink of intended display color can be adopted repeatedly to print; As shown in Figure 7, the ink of intended display color can be adopted to perform twice serigraphy process, thus obtain corresponding two-layer ink, and common formation shows ink layer, for performance intended display color.Similarly, for reasons such as enhancing shaded effects, the ink of shading color also can be adopted repeatedly to print; As shown in Figure 7, after adopting the ink of shading color to carry out one or many printing, obtain one or more layers ink corresponding and constitute black-out ink layer, for panel shading.
2, laser engraving process
As shown in Figure 8, (or to claim by performing laser engraving process from face glass back, radium is carved), all ink layeies that serigraphy process obtains can be penetrated, and the pattern of default virtual key is formed at face glass back, time then from view shown in Fig. 8, preset the transparent shape of pattern of virtual key.
For highlighting default virtual key, or avoid the internal structure appearing mobile device, further process can be done to virtual key, namely for the serigraphy process of this default virtual key:
According to the button color preset, adopt the default virtual key region at the ink counter plate structure back of described button color to carry out serigraphy process at least one times, obtain the button ink layer covering default virtual key.
As shown in Figure 9, when carrying out serigraphy process from face glass back to default virtual key region, displaying ink layer and black-out ink layer has all been printed due to around the default virtual key that laser engraving goes out, thus the positioning requirements for button ink layer is very low, only needs to cover default virtual key; Even if by ink printing to the region of presetting outside virtual key, because this completes at face glass back, thus can't embody in face glass front.
In this embodiment, in order to highlight default virtual key, making default virtual key be different from the front end color of mobile device, button colouring discrimination can be made in intended display color.
In this embodiment, in order to reach the colouring object of default virtual key, and guarantee that the backlight below default virtual key can light this default virtual key, as shown in Figure 10, can by default virtual key printing to be translucent and can transmitted light.Can be accomplished in several ways the default virtual key of above-mentioned effect, the disclosure does not limit this; For example, can be realized by following manner:
In a kind of situation, the gray value of button color can be made lower than default gray value, such as use the grey that gray value is lower, thus make button ink layer the same with displaying ink layer, there is the situation that can pass through light because gray scale is low.
In another kind of situation, the thickness of button ink layer can be made lower than preset thickness, default virtual key is translucent and can transmitted light.
Those skilled in the art, at consideration description and after putting into practice disclosed herein disclosing, will easily expect other embodiment of the present disclosure.The application is intended to contain any modification of the present disclosure, purposes or adaptations, and these modification, purposes or adaptations are followed general principle of the present disclosure and comprised the undocumented common practise in the art of the disclosure or conventional techniques means.Description and embodiment are only regarded as exemplary, and true scope of the present disclosure and spirit are pointed out by claim below.
