具体实施方式Detailed ways
下面结合本发明的附图对本发明实施例中的技术方案进行清楚、完整的描述,显然,所描述的实施例仅仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
结合图1-4对本发明实施例的用于移动终端的低功耗的显示装置进行说明。A low power consumption display device for a mobile terminal according to an embodiment of the present invention will be described with reference to FIGS. 1-4 .
本发明实施例中的移动终端,可为手机、平板电脑或智能可穿戴设备等,用于这些移动终端的显示装置自上而下包括:透明显示层1、贴合层3和反射式显示层2,其中,所述透明显示层1由透明物质制成,具有完全透光能力,且通电后可自发光。所述显示装置可通过所述透明显示层1的自发光、或通过所述反射式显示层2对环境光的反射两种方式之一实现显示。The mobile terminal in the embodiment of the present invention can be a mobile phone, a tablet computer or a smart wearable device, etc. The display device used for these mobile terminals includes from top to bottom: a transparent display layer 1, a bonding layer 3 and a reflective display layer 2. Wherein, the transparent display layer 1 is made of a transparent material, has complete light transmission ability, and can emit light automatically after electrification. The display device can display in one of two ways: self-illumination of the transparent display layer 1 or reflection of ambient light by the reflective display layer 2 .
本实施例中,中间的贴合层3主要用于实现所述透明显示层1与反射式显示层2的全贴合(full lamination)。全贴合也称之为non-air-gap技术,与传统贴合方式相比,全贴合是将面板黏贴上外层玻璃(或触控面板),由于中间为真空状态,因此可免去光线的折射问题,但若是传统口字胶贴合,则很容易就可以看出像似两片玻璃一样的叠影现象。此外,全贴合更可让显示屏更具高辉度与高画质的真实感,尤其是在户外强光环境之下,可清晰看见终端显示屏的显示内容。In this embodiment, the laminating layer 3 in the middle is mainly used to realize full lamination of the transparent display layer 1 and the reflective display layer 2 . Full lamination is also called non-air-gap technology. Compared with the traditional lamination method, full lamination is to paste the panel on the outer glass (or touch panel). Since the middle is in a vacuum state, it can avoid The problem of refraction of light is removed, but if it is pasted with traditional word-of-mouth glue, it is easy to see the superimposition phenomenon like two pieces of glass. In addition, full lamination can make the display more realistic with high brightness and high image quality, especially in the outdoor strong light environment, the display content of the terminal display can be clearly seen.
本实施例中,所述透明显示层1、反射式显示层2的全贴合方式包括背胶贴合、水胶贴合或固体胶贴合等。In this embodiment, the full lamination of the transparent display layer 1 and the reflective display layer 2 includes back glue lamination, water glue lamination, or solid glue lamination.
进一步的,本实施例的显示装置还设有光传感器,用于检测环境光的光照度。可根据实际情况设定所述光传感器周期性的获取环境光的光照度信息。Further, the display device of this embodiment is further provided with a light sensor for detecting the illuminance of ambient light. The light sensor may be set to periodically acquire illuminance information of ambient light according to actual conditions.
进一步的,下面对本实施例的显示装置的控制流程进行说明,如图4所示,包括如下步骤:Further, the following describes the control flow of the display device in this embodiment, as shown in FIG. 4, including the following steps:
步骤S101,获取环境光的光照度信息。Step S101, acquiring illuminance information of ambient light.
光照度是指光(自然光源或人工光源)射到的一个平面的光通量密度,即每平方米的平面上通过的光量,单位为勒克斯(LX),1LX的光量相当于一根蜡烛的发光量。在同一个房间内,距离光源的远近不同,不同地点的光照度就不相同。Illuminance refers to the luminous flux density of a plane hit by light (natural light source or artificial light source), that is, the amount of light passing on a plane per square meter, the unit is lux (LX), and the amount of light of 1LX is equivalent to the luminous amount of a candle. In the same room, the distance from the light source is different, and the illuminance of different places is different.
根据实际情况,可按照预设时间周期获取环境光的光照度信息,以实时控制显示装置的显示模式。According to the actual situation, the illuminance information of the ambient light can be acquired according to a preset time period, so as to control the display mode of the display device in real time.
步骤S102,将所述光照度信息与设定值进行比对。Step S102, comparing the illuminance information with a set value.
步骤S103,是否小于所述设定值?若是,执行步骤S104,否则,执行步骤S105。Step S103, is it smaller than the set value? If yes, execute step S104, otherwise, execute step S105.
可根据实际情况设定所述设定值,例如50勒克斯、100勒克斯、200勒克斯等。The set value can be set according to the actual situation, for example, 50 lux, 100 lux, 200 lux and so on.
步骤S104,启动自发光显示模式,控制所述透明显示层1通电,所述显示装置通过所述透明显示层1的自发光实现显示。Step S104, start the self-luminous display mode, control the transparent display layer 1 to be powered on, and the display device realizes display through the self-luminous light of the transparent display layer 1 .
在自发光显示模式下,如图2所示,所述透明显示层1的自发光光线进入人眼,即对于人眼而言,所述透明显示层1为显示层。In the self-luminous display mode, as shown in FIG. 2 , the self-luminous light of the transparent display layer 1 enters human eyes, that is, the transparent display layer 1 is a display layer for human eyes.
步骤S105,启动反射显示模式,控制所述透明显示层1断电,所述显示装置通过所述反射式显示层2对环境光的反射实现显示。Step S105, start the reflective display mode, control the transparent display layer 1 to be powered off, and the display device realizes display through the reflection of ambient light by the reflective display layer 2 .
在反射显示模式下,如图3所示,所述透明显示层1断电不再自发光,所述反射式显示层2对环境光线进行反射(所述透明显示层1对入射、反射的环境光无影响)后进入人眼,即对于人眼而言,所述反射式显示层2为显示层。该模式下由于借助环境光实现显示,有利于节省功耗,提高移动终端电池的续航能力。In the reflective display mode, as shown in FIG. 3 , the transparent display layer 1 is powered off and no longer emits light by itself, and the reflective display layer 2 reflects ambient light (the transparent display layer 1 responds to incident and reflective environments. Light has no effect) enters the human eye, that is, for the human eye, the reflective display layer 2 is a display layer. In this mode, since the display is realized by means of ambient light, it is beneficial to save power consumption and improve battery life of the mobile terminal.
步骤S106,若接收到切换显示模式的用户操作指令,执行所述反射显示模式与所述自发光显示模式的切换。Step S106, if a user operation instruction for switching display modes is received, switch between the reflective display mode and the self-luminous display mode.
本实施例的显示装置可通过软件算法和(或)硬件防冲突器件,选择透明显示层1和反射式显示层2之一进行显示,可自动选择实现,例如处理器根据检测到的环境光强度自动进行控制;也可以接受用户操作指令通过手动选择实现,例如通过相应的按键来进行显示模式的切换,假设当前显示模式为的反射显示模式,检测到用户按下对应按键之后,切换为透明显示模式进行显示。The display device of this embodiment can select one of the transparent display layer 1 and the reflective display layer 2 to display through software algorithms and (or) hardware anti-collision devices, which can be automatically selected and realized, for example, according to the detected ambient light intensity by the processor Automatic control; it can also accept user operation instructions through manual selection, such as switching the display mode through the corresponding button, assuming that the current display mode is the reflective display mode, after detecting that the user presses the corresponding button, switch to transparent display mode is displayed.
通过本发明实施例的低功耗的显示装置,当环境光线比较充足时,通过对环境光的反射实现显示,有利于节省功耗;当环境光线比较暗时,通过自发光实现显示。本方案的显示装置兼顾强光和弱光环境的显示效果,并且功耗低,有利于提高移动终端电池的续航能力。With the low power consumption display device of the embodiment of the present invention, when the ambient light is relatively sufficient, the display is realized by reflecting the ambient light, which is beneficial to save power consumption; when the ambient light is relatively dark, the display is realized by self-luminescence. The display device of the present solution takes into account the display effects in both strong light and low light environments, and has low power consumption, which is beneficial to improving battery life of the mobile terminal.
以上所揭露的仅为本发明较佳实施例而已,当然不能以此来限定本发明之权利要求范围,因此,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,仍属本发明所涵盖的范围。The above disclosures are only preferred embodiments of the present invention, and certainly cannot limit the scope of the claims of the present invention. Therefore, any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention, Still belong to the scope covered by the present invention.
