本申请涉及显示设备技术领域,具体而言,涉及一种多功能显示装置、显示驱动方法和投影驱动方法。The present application relates to the technical field of display devices, and in particular, to a multifunctional display device, a display driving method, and a projection driving method.
随着人们对生活质量的要求越来越高,对于居家追剧、观影的要求也越来越多,对投影仪的要求越来越高。目前,显示屏和投影仪都成为了居家必备的观影设备,但是显示屏仅仅具有显示的功能,而投影仪仅仅具有投影的功能,二者只能分开使用,占据的空间比较多。As people's requirements for the quality of life are getting higher and higher, there are more and more requirements for watching dramas and watching movies at home, and the requirements for projectors are getting higher and higher. At present, both the display screen and the projector have become necessary viewing devices at home, but the display screen only has the function of display, while the projector only has the function of projection, and the two can only be used separately, occupying a lot of space.
也就是说,现有技术中显示屏存在功能单一的问题。That is to say, the display screen in the prior art has the problem of single function.
发明内容Contents of the invention
鉴于上述现有技术的不足,本申请的目的在于提供一种多功能显示装置、显示驱动方法和投影驱动方法,旨在解决现有技术中显示屏存在功能单一的问题。In view of the above deficiencies in the prior art, the purpose of the present application is to provide a multifunctional display device, a display driving method and a projection driving method, aiming at solving the problem of single function of the display screen in the prior art.
一种多功能显示装置,包括:显示屏,显示屏具有第一显示区域和第二显示区域,第一显示区域的面积大于第二显示区域的面积,第二显示区域位于显示屏的边缘处;投影组件,投影组件设置在显示屏上且与第二显示区域对应,用于将第二显示区域的图像投影到投影屏上。A multifunctional display device, comprising: a display screen, the display screen has a first display area and a second display area, the area of the first display area is larger than the area of the second display area, and the second display area is located at the edge of the display screen; The projection component is arranged on the display screen and corresponds to the second display area, and is used for projecting the image of the second display area onto the projection screen.
通过将显示屏设置成第一显示区域和第二显示区域,第一显示区域仅仅用于显示,以使得显示屏能够实现显示的功能。而第二显示区域可以用于显示,也可以用于投影。在第二显示区域与投影组件配合时,可以实现 投影的功能。而第二显示区域还可以与第一显示区域同时显示,以使得整个显示屏能够显示一个完整的图案。第一显示区域的面积大于第二显示区域的面积。这样设置使得显示屏的大部分面积用来显示,只有小部分面积用于投影,能够保证显示屏的显示功能。同时投影组件需要的光源的面积也比较小,有利于第二显示区域发出的光束全部进入到投影组件内。由于投影组件安装到显示屏上,且投影组件的至少一部分与第二显示区域正对设置,以使第二显示区域发射的光束射入到投影组件内。将第二显示区域设置在显示屏的边缘处,便于将投影组件与显示屏安装到一起,且投影组件不会对第一显示区域造成遮挡,保证第一显示区域工作的稳定性。By setting the display screen as a first display area and a second display area, the first display area is only used for display, so that the display screen can realize the function of display. The second display area can be used for display or projection. When the second display area cooperates with the projection component, the function of projection can be realized. The second display area can also be displayed simultaneously with the first display area, so that the entire display screen can display a complete pattern. The area of the first display area is larger than the area of the second display area. Such setting makes most of the area of the display screen be used for display, and only a small part of the area is used for projection, which can ensure the display function of the display screen.

正如背景技术部分所描述的,现有技术中存在显示屏存在功能单一的问题。As described in the background section, there is a problem that the display screen has a single function in the prior art.
基于此,本申请希望提供一种能够解决上述技术问题的方案,其详细内容将在后续实施例中得以阐述。Based on this, the present application hopes to provide a solution capable of solving the above-mentioned technical problems, the details of which will be described in subsequent embodiments.
如图1至图7所示,多功能显示装置包括显示屏10和投影组件20,显示屏10具有第一显示区域11和第二显示区域12;投影组件20设置在显示屏10上且与第二显示区域12对应,用于将第二显示区域12的图像投影到投影屏上。As shown in Figures 1 to 7, the multifunctional display device includes a display screen 10 and a projection assembly 20, the display screen 10 has a first display area 11 and a second display area 12; the projection assembly 20 is arranged on the display screen 10 and is connected to the second display area The two display areas 12 correspond to each other, and are used to project the image of the second display area 12 onto the projection screen.
通过将显示屏10设置成第一显示区域11和第二显示区域12,第一显示区域11仅仅用于显示,以使得显示屏10能够实现显示的功能。而第二显示区域12可以用于显示,也可以用于投影。在第二显示区域12与投影组件20配合时,可以实现投影的功能。而第二显示区域12还可以与第一显示区域11同时显示,以使得整个显示屏10能够显示一个完整的图案。By setting the display screen 10 into a first display area 11 and a second display area 12 , the first display area 11 is only used for display, so that the display screen 10 can realize the function of display. The second display area 12 can be used for display or projection. When the second display area 12 cooperates with the projection assembly 20, the function of projection can be realized. The second display area 12 can also be displayed simultaneously with the first display area 11, so that the entire display screen 10 can display a complete pattern.
具体的,多功能显示装置具有显示状态、投影状态和投影加显示状态,多功能显示装置处于显示状态时,第一显示区域11和第二显示区域12显示并拼接成一个画面,多功能显示装置处于投影状态时,仅第二显示区域12显示并被投影组件20投影,多功能显示装置处于投影加显示状态时,第一显示区域11显示第一画面,第二显示区域12显示第二画面且第二画面被投影组件20投影。Specifically, the multi-function display device has a display state, a projection state, and a projection plus display state. When the multi-function display device is in the display state, the first display area 11 and the second display area 12 are displayed and spliced into one picture. The multi-function display device When in the projection state, only the second display area 12 is displayed and projected by the projection assembly 20; when the multi-function display device is in the projection plus display state, the first display area 11 displays the first picture, the second display area 12 displays the second picture and The second picture is projected by the projection component 20 .
多功能显示装置处于显示状态时,第一显示区域11和第二显示区域12均处于工作状态,此时数据同时传输至第一显示区域11和第二显示区域12内,使得第一显示区域11和第二显示区域12同时工作并显示同一个画面,使得显示屏10实现显示的功能。而当多功能显示装置处于投影状态时,此时数据仅传输至第二显示区域12内,第二显示区域12所射出的光束可以作为投影光源使用,第二显示区域12射出的光射入到投影组件20内,以实现投影的功能。当多功能显示装置处于投影加显示状态时,第一显示区域11显示第一画面,第二显示区域12显示第二画面,第一画面和第二画面可以是相同的,也可以是不同的。但是在投影加显示状态时第二画面是一个完整的画面,而不是第一画面的一部分。这样就可以实现一个显示屏10可以同时实现显示的功能也能够实现投影的功能。When the multi-function display device is in the display state, the first display area 11 and the second display area 12 are all in the working state, and now the data are transmitted to the first display area 11 and the second display area 12 simultaneously, so that the first display area 11 It works simultaneously with the second display area 12 and displays the same picture, so that the display screen 10 realizes the display function. And when the multifunctional display device is in the projection state, the data is only transmitted to the second display area 12 at this time, the light beam emitted by the second display area 12 can be used as a projection light source, and the light emitted by the second display area 12 enters the In the projection assembly 20, to realize the function of projection. When the multi-function display device is in the projection plus display state, the first display area 11 displays the first picture, and the second display area 12 displays the second picture. The first picture and the second picture may be the same or different. But in the state of projection and display, the second picture is a complete picture, not a part of the first picture. In this way, it can be realized that one display screen 10 can realize the function of display and the function of projection at the same time.
具体的,在多功能显示装置处于显示状态时,控制第二显示区域12中的第二LED芯片14,使得几个邻近的第二LED芯片14共同显示为画面的一个子像素,这样第二显示区域12所显示的一个像素的尺寸与第一显示区 域11所显示的一个像素的尺寸相等,使得第一显示区域11和第二显示区域12所显示的画面能够拼接成一个完整的画面。Specifically, when the multifunctional display device is in the display state, the second LED chips 14 in the second display area 12 are controlled so that several adjacent second LED chips 14 are displayed together as a sub-pixel of the screen, so that the second display The size of a pixel displayed in the area 12 is equal to the size of a pixel displayed in the first display area 11 , so that the images displayed in the first display area 11 and the second display area 12 can be spliced into a complete image.
如图5所示,第一显示区域11的面积大于第二显示区域12的面积。这样设置使得显示屏10的大部分面积用来显示,只有小部分面积用于投影,能够保证显示屏10的显示功能。同时投影组件20需要的光源的面积也比较小,有利于第二显示区域12发出的光束全部进入到投影组件20内。As shown in FIG. 5 , the area of the first display region 11 is larger than the area of the second display region 12 . In this way, most of the area of the display screen 10 is used for display, and only a small part of the area is used for projection, which can ensure the display function of the display screen 10 . At the same time, the area of the light source required by the projection assembly 20 is also relatively small, which is beneficial for all light beams emitted by the second display area 12 to enter into the projection assembly 20 .
如图5所示,第二显示区域12位于显示屏10的边缘处。由于投影组件20安装到显示屏10上,且投影组件20的至少一部分与第二显示区域12正对设置,以使第二显示区域12发射的光束射入到投影组件20内。将第二显示区域12设置在显示屏10的边缘处,便于将投影组件20与显示屏10安装到一起,且投影组件20不会对第一显示区域11造成遮挡,保证第一显示区域11工作的稳定性。As shown in FIG. 5 , the second display area 12 is located at the edge of the display screen 10 . Since the projection assembly 20 is installed on the display screen 10 , and at least a part of the projection assembly 20 is disposed opposite to the second display area 12 , the light beam emitted by the second display area 12 enters the projection assembly 20 . Setting the second display area 12 at the edge of the display screen 10 is convenient for installing the projection assembly 20 and the display screen 10 together, and the projection assembly 20 will not block the first display area 11, ensuring that the first display area 11 works stability.
需要说明的是,第二显示区域12位于显示屏10的边缘处包括两种情况,一种情况是:第二显示区域12与显示屏10的侧壁是连接的。另一种情况是:第二显示区域12与显示屏10的侧壁之间间隔一定的距离的,但是第二显示区域12与显示屏10的所有的侧壁的最小的距离比第二显示区域12到显示屏10的中心点的距离小,以保证第二显示区域12相对于显示屏10的中心靠近显示屏10上第二显示区域12对应的一侧边缘。It should be noted that there are two cases where the second display area 12 is located at the edge of the display screen 10 . One case is that the second display area 12 is connected to the side wall of the display screen 10 . Another situation is: there is a certain distance between the second display area 12 and the side walls of the display screen 10, but the minimum distance between the second display area 12 and all the side walls of the display screen 10 is greater than that of the second display area 12. 12 to the center point of the display screen 10 is small to ensure that the second display area 12 is close to the edge of the side corresponding to the second display area 12 on the display screen 10 relative to the center of the display screen 10 .
具体的,投影组件20与显示屏10可拆卸地连接。这样设置便于投影组件20的维修和更换,同时将投影组件20拆卸下来在多功能显示装置处于显示状态时,投影组件20不再遮挡第二显示区域12,使得第一显示区域11和第二显示区域12能够显示一个完整的画面。Specifically, the projection assembly 20 is detachably connected to the display screen 10 . This arrangement is convenient for the maintenance and replacement of the projection assembly 20, and when the projection assembly 20 is disassembled when the multi-function display device is in the display state, the projection assembly 20 no longer blocks the second display area 12, so that the first display area 11 and the second display area Area 12 can display a complete picture.
具体的,第一显示区域11内的LED芯片与第二显示区域12内的LED芯片不同。通过将第一显示区域11内的LED芯片与第二显示区域12内的LED芯片设置成不同的,就使得第二显示区域12能够用于投影。Specifically, the LED chips in the first display area 11 are different from the LED chips in the second display area 12 . By setting the LED chips in the first display area 11 differently from the LED chips in the second display area 12, the second display area 12 can be used for projection.
需要说明的是,并不是所有的LED芯片均能用于投影,所以第二显示区域12内的LED芯片是既能够用于投影也能够用于显示的芯片。It should be noted that not all LED chips can be used for projection, so the LED chips in the second display area 12 are chips that can be used for both projection and display.
具体的,显示屏10包括第一LED芯片13和第二LED芯片14,第一LED芯片13设置在第一显示区域11内;第二LED芯片14设置在第二显示区域12内,第一LED芯片13的尺寸大于第二LED芯片14的尺寸。这样设置在保证多功能显示装置能正常工作的情况下,尽可能减少制作成本。Specifically, the display screen 10 includes a first LED chip 13 and a second LED chip 14, the first LED chip 13 is set in the first display area 11; the second LED chip 14 is set in the second display area 12, the first LED chip The size of the chip 13 is larger than the size of the second LED chip 14 . This setting reduces the production cost as much as possible while ensuring the normal operation of the multi-functional display device.
具体的,第一LED芯片13是mini-led芯片,而第二LED芯片14是micro-led芯片。第二LED芯片14发出的光能够作为投影光源使用。Specifically, the first LED chip 13 is a mini-led chip, and the second LED chip 14 is a micro-led chip. The light emitted by the second LED chip 14 can be used as a projection light source.
当然,第一LED芯片13和第二LED芯片14的尺寸可以是相同的,例如都是micro-led芯片,micro-led芯片尺寸小、显示精度高。Certainly, the size of the first LED chip 13 and the second LED chip 14 may be the same, for example, both are micro-led chips, and the size of the micro-led chips is small and the display accuracy is high.
如图1、图2、图6和图7所示,投影组件20包括投影箱21和投影镜头组件24,投影箱21具有光学腔22和安装槽23,光学腔22与安装槽23连通,显示屏10位于安装槽23内,且显示屏10的显示面朝向光学腔22;投影镜头组件24位于光学腔22内,以将显示屏10发出的光投影到投影屏上。投影镜头组件24容置在投影箱21内,投影箱21对投影镜头组件24形成保护,保证投影镜头组件24稳定工作,同时投影箱21能够减少外部光源射入到投影镜头组件24上,大大减少了杂散光的产生,增加了投影镜头组件24成像的清晰度。显示屏10插入到安装槽23内,使得投影组件20与显示屏10实现安装,同时第二显示区域12进入到投影箱21内,第二显示区域12发出的光线能够射向投影镜头组件24内实现投影。As shown in Figures 1, 2, 6 and 7, the projection assembly 20 includes a projection box 21 and a projection lens assembly 24, the projection box 21 has an optical cavity 22 and a mounting groove 23, and the optical cavity 22 communicates with the mounting groove 23, showing The screen 10 is located in the installation groove 23 , and the display surface of the display screen 10 faces the optical cavity 22 ; the projection lens assembly 24 is located in the optical cavity 22 to project the light emitted by the display screen 10 onto the projection screen. The projection lens assembly 24 is accommodated in the projection box 21, and the projection box 21 forms protection for the projection lens assembly 24 to ensure the stable operation of the projection lens assembly 24. At the same time, the projection box 21 can reduce the incidence of external light sources on the projection lens assembly 24, greatly reducing the The generation of stray light is reduced, and the imaging definition of the projection lens assembly 24 is increased. The display screen 10 is inserted into the installation groove 23, so that the projection assembly 20 and the display screen 10 are installed, and at the same time, the second display area 12 enters the projection box 21, and the light emitted by the second display area 12 can be directed into the projection lens assembly 24 Realize the projection.
