Embodiment
Carry out clear, complete description below in conjunction with accompanying drawing of the present invention to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of protection of the invention.
The display device of composition graphs 1-4 to the low-power consumption for mobile terminal of the embodiment of the present invention is described.
Mobile terminal in the embodiment of the present invention, can be mobile phone, panel computer or intelligent wearable device etc., display device for these mobile terminals comprises from top to bottom: transparent display layer 1, laminating layer 3 and reflective display layer 2, wherein, described transparent display layer 1 is made up of transparency material, there is complete transmittancy, and can autoluminescence after energising.One of the autoluminescence of described display device by described transparent display layer 1 or the reflection two kinds of modes by described reflective display layer 2 pairs of surround lightings realize display.
In the present embodiment, middle laminating layer 3 is mainly used in the full laminating (full lamination) realizing described transparent display layer 1 and reflective display layer 2.Full laminating is also referred to as non-air-gap technology, compared with traditional laminating type, panel pasted upper glass outer (or contact panel) in full laminating, because centre is vacuum state, therefore the refraction problems of light can be removed from, if but traditional mouth word glue laminating, be then easy to just to find out the ghost image phenomenon as like two sheet glass.In addition, full laminating more can allow display screen have more the sense of reality of high briliancy and high image quality, especially out of doors under strong light environment, clearly can see the displaying contents of terminal display screen.
In the present embodiment, the full laminating type of described transparent display layer 1, reflective display layer 2 comprises gum laminating, glue laminating or solid gum laminating etc.
Further, the display device of the present embodiment is also provided with optical sensor, for the illuminance of ambient light.The illuminance information that described optical sensor periodically obtains surround lighting can be set according to actual conditions.
Further, below the control flow of the display device of the present embodiment is described, as shown in Figure 4, comprises the steps:
Step S101, obtains the illuminance information of surround lighting.
Illuminance refers to the pharosage of the plane that light (lamp or artificial light source) is mapped to, and the light quantity namely plane of every square metre passed through, unit is lux (LX), and the light quantity of 1LX is equivalent to the luminous quantity of a candle.In same room with them, the distance of distance light source is different, and the illuminance of different location is just not identical.
According to actual conditions, the illuminance information of surround lighting can be obtained according to preset time period, to control the display mode of display device in real time.
Step S102, compares described illuminance information and setting value.
Does is step S103, less than described setting value? if so, step S104 is performed, otherwise, perform step S105.
Described setting value can be set, such as 50 luxs, 100 luxs, 200 luxs etc. according to actual conditions.
Step S104, starts autoluminescence display mode, controls described transparent display layer 1 and be energized, and described display device realizes display by the autoluminescence of described transparent display layer 1.
Under autoluminescence display mode, as shown in Figure 2, the autoluminescence light of described transparent display layer 1 enters human eye, and namely for human eye, described transparent display layer 1 is display layer.
Step S105, starts reflection display mode, controls the power-off of described transparent display layer 1, and described display device realizes display by the reflection of described reflective display layer 2 pairs of surround lightings.
Under reflection display mode, as shown in Figure 3, described transparent display layer 1 power-off no longer autoluminescence, described reflective display layer 2 enters human eye after reflecting (described transparent display layer 1 on the surround lighting of incident, reflection without impact) to ambient light, namely, for human eye, described reflective display layer 2 is display layer.Owing to realizing display by surround lighting under this pattern, be conducive to saving power consumption, improve the flying power of battery of mobile terminal.
Step S106, if receive the user operation instruction switching display mode, performs the switching of described reflection display mode and described autoluminescence display mode.
The display device of the present embodiment is by software algorithm and (or) hardware anti-collision device, one of transparent display layer 1 and reflective display layer 2 is selected to show, can automatically select to realize, such as processor controls automatically according to the ambient light intensity detected; Also can accept user operation instruction manually to select to realize, the switching of display mode is such as carried out by corresponding button, suppose the reflection display mode that current display mode is, after detecting that user presses corresponding button, switch to Transparence Display pattern to show.
By the display device of the low-power consumption of the embodiment of the present invention, when ambient light is more sufficient, by realizing display to the reflection of surround lighting, be conducive to saving power consumption; When ambient light is darker, realize display by autoluminescence.The display device of this programme takes into account the display effect of high light and low light environment, and low in energy consumption, is conducive to the flying power improving battery of mobile terminal.
Above disclosedly be only present pre-ferred embodiments, certainly the right of the present invention can not be limited with this, therefore, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., still belong to the scope that the present invention is contained.
