Embodiment
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is done further detailed explanation.
The present invention is directed to mobile devices such as having mobile phone now adopts single display screen in some light environment, to show unclear; If will be clear that the deficiency that demonstration need increase electric current, consume more electric weight; A kind of display packing that has proposed to adopt double-deck display screen, in the different light rays environment, shown respectively; Each sheet display screen through in the double-deck display screen of choose reasonable can be implemented in the purpose that all can know demonstration in the different light rays environment.
Shown in Figure 1 is the process flow diagram of an embodiment of display packing according to the invention.
This embodiment is from point of practical use; With the mobile phone is example; The cellphone subscriber by day, the mobile phone operation that carried out down of high light environment such as outdoor is simple information inspection or menu operation mostly, as check time, note, telephone directory, message registration etc., and functions such as multimedia, recreation are used seldom; In the case, monochromatic display screen can satisfy user's demand.The user needs colorful display screen to show again when functions such as use multimedia, recreation.Therefore, this embodiment selects for use stn liquid crystal display screen and TFT colorful display screen mutual superposition to be in the same place, and constitutes double-deck display screen structure.Select for use the stn liquid crystal display screen to also have an advantage, be exactly this display screen be pellucidity when closing, do not influence passing through of light.Therefore, with the stn liquid crystal display screen as upper strata display screen, TFT colorful display screen as lower floor's display screen, both superpose and form upper and lower two-layer display screen structure.Because the operating characteristic of stn liquid crystal display screen is that ambient light is stronger, display effect is good more, and that the operating characteristic of TFT colorful display screen is an ambient light is more weak, display effect is good more, therefore, adopts the demonstration of following step realization display screen:
S1: stn liquid crystal display screen and these two display screens of TFT colorful display screen are superimposed, the stn liquid crystal display location in the upper strata, the TFT colorful display screen is positioned at lower floor, forms double-deck display screen structure.
S2: the testing environment light intensity, with the control of confirming display screen is opened and closed.
S3: judge that whether the ambient light intensity that is detected is greater than setting value; If greater than setting value, execution in step S5; If be not more than setting value, execution in step S4.
S4: if the ambient light intensity level is not more than setting value, show that ambient light a little less than, at this moment, the TFT colorful display screen of opening lower floor carries out content and shows, satisfying the demand that the user shows colour, and the stn liquid crystal display screen of closing the upper strata.After the stn liquid crystal display screen on upper strata is closed, be in pellucidity, have higher transmittance, can have an X-rayed underlying TFT colorful display screen content displayed.
S5: if the ambient light intensity level greater than setting value, shows that ambient light is stronger, then open the stn liquid crystal display screen on upper strata, be used to show content corresponding, and the TFT colorful display screen of closing lower floor, to guarantee display effect clearly.
Said upper strata display screen also can adopt TN LCDs or film radiation shield to realize; Said lower floor display screen also can adopt UFB colorful display screen or color OLED display screen to realize.
Fig. 2 shows the structured flowchart of an embodiment of display system according to the invention.
As shown in Figure 2, the display system of this embodiment comprises display module, control module and light intensity detection module.
Said display module comprises upper strata display screen and lower floor's display screen, and two display screen mutual superposition form upper and lower two-layer display screen structure.
Said light intensity detection module is used for the testing environment light intensity, and exports corresponding light intensity signal to said control module.Whether said control module is controlled said light intensity detection module on the one hand and is worked, on the other hand will be according to the light intensity signal that received output control signal corresponding, control that wherein a slice display screen in the two-layer display screen is opened and another sheet display screen is closed.
In this embodiment, said upper strata display screen adopts the TN LCDs, and said lower floor display screen adopts the TFT colorful display screen.The operating characteristic of TN LCDs is that ambient light is stronger, display effect is good more, and that the operating characteristic of TFT colorful display screen is an ambient light is more weak, display effect is good more.Therefore, said control module at first compares this ambient light intensity level and a setting value behind the light intensity signal that receives said light intensity detection module output.If the ambient light intensity level, is then exported control signal greater than setting value and controlled said upper strata display screen and open and close said lower floor display screen, showing with said upper strata display screen needs content displayed; If the ambient light intensity level is not more than setting value, then export control signal and control said lower floor display screen and open and close said upper strata display screen, showing with said lower floor display screen needs content displayed.So; Utilize said control module that control is unified, coordinated to two display screens, under the varying environment light intensity, select different display screens to carry out content and show; Guarantee under the different light rays environment, all can obtain displaying contents clearly, be convenient to the user and check.
For ease of the installation of display module, said upper strata display screen and said lower floor display screen are packaged together, and form all-in-one-piece display screen structure.To seal during encapsulation, get into to prevent dust.
Said light intensity detection module can adopt optical sensor to realize.
The display system of the foregoing description can be applied on the mobile devices such as mobile phone, makes the user can under high-brightness environment, see the displaying contents of display screen clearly, and can not expend more electric weight because of frequently checking display screen; Can under the low-light level environment, use colored multimedia display again, strengthen the adaptive faculty of mobile device, improve its display performance.
Above embodiment is only in order to explaining technical scheme of the present invention, but not limits it; Although the present invention has been carried out detailed explanation with reference to previous embodiment, for the person of ordinary skill of the art, still can make amendment to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of relevant art scheme break away from the spirit and the scope of the present invention's technical scheme required for protection.
