The display area referred to here may represent only the display portion of the display screen or all the parts that can form the screen. Of course, the display screen 101 may also include three or more display areas, and is not limited to two.

The fact that the two display areas are independent of each other means that the opening and closing of one of the display areas does not affect the opening and closing of the other display area, that is, the first display area 104 and the second display area 105 can illuminate one of them, or can be lit at the same time or Close at the same time. According to different needs, choose to work one display area separately or make two display areas work at the same time. When only one display area works, the other display area is closed, and the closed display area is in common with the mirror surface of the inner rear view mirror. The scene behind the car is reflected, and the reflection area is increased, which can effectively expand the driver's field of vision; when the two display areas work at the same time, different contents can be displayed, of course, two display areas The pictures can be spliced to each other, that is, each display area displays a part of the entire picture, and it is also possible to form a complete picture after splicing.

The display screen 101 includes two display areas, which may take various forms, for example, two independent display parts 107, and may be used, but not limited to the following preferred schemes: as shown in FIGS. 6 to 11, the display screen 101 includes a frame 106. And a display member 107, the display member 107 is disposed in the frame 106, the frame 106 is for fixing the display member 107, and the display member 107 is for displaying a picture.

The display unit 107 includes a display screen 108 stacked in sequence, a first backlight layer 109, a second backlight layer 110, a third backlight layer 111, a fourth backlight layer 112, and a fifth backlight layer 119. The display screen 108 is made of liquid crystal glass. Or the LCD display glass, the first display area 104 and the second display area 105 are both located on the display screen 108, and the screen holder 113 is disposed around the display member 107.

There is also a case in the car interior rearview mirror in the market, that is, when only a part of the text or icon is displayed on the display screen, since the entire display screen adopts a backlight, the area on the display screen where no text or icon is displayed is still There is a certain brightness, and the reflection area of the inner mirror glass is dark, which is visually obvious and is easy to cause visual interference to the driver. In order to improve the problem, in the present invention, the screen holder 113 is provided with a first backlight 114 and a second backlight 115 which are independent of each other, and the first backlight 114 and the second backlight 115 are respectively disposed side by side on the two sides of the screen bracket 113. The light bar group, that is, each backlight includes two light bar groups, two light bar groups are disposed in parallel on both sides of the screen support 113, and the first backlight 114 and the second backlight 115 are respectively used to form the first display area 104. And a second display area 105.

The first backlight layer 109, the second backlight layer 110, the third backlight layer 111, the fourth backlight layer 112, and the fifth backlight layer 119 may sequentially be a brightness enhancement film, a backlight film, a diffusion film, a light guide plate, and a reverse The film, of course, can be changed or added or removed as needed. In addition, it is also possible to change the diaphragms of different backlight layers as needed.

As a preferred embodiment of the embodiment, as shown in FIG. 7 and FIG. 9, the third backlight layer 111 includes a fifth backlight film and a sixth backlight film disposed side by side, and the fifth backlight film and the sixth backlight film are located. In the same plane.

If there is no blocking portion between the fifth backlight film and the sixth backlight film, a backlight or the like in one of the display regions may affect components in the other display region. As shown in FIG. 11, the screen holder 113 is provided with a thin portion. The wall 116, the two ends of the thin wall 116 are respectively connected to opposite sides of the screen bracket 113, and the fifth backlight film and the sixth backlight film, and the seventh backlight film and the eighth backlight film are respectively disposed on the thin wall 116. On both sides, here, the fifth backlight film and the sixth backlight film are respectively disposed on both sides of the thin wall 116, and the seventh backlight film and the eighth backlight film are respectively disposed on both sides of the thin wall 116. The structural meanings mentioned below can be the same as the same. The thin wall 116 can be used not only to support the components on both sides, but also to block the backlight, to prevent the backlight from being prohibited from being in an unnecessary area, and to ensure an unlit display area. Unaffected by the backlight, the multi-display function of one screen is realized, and the unlit display area and the mirror surface cooperate to reflect the condition behind the automobile, thereby effectively increasing the mirror surface of the rear view mirror of the automobile.

There are two ways in which the display screen 101 can be divided into two display areas:

First, as shown in FIG. 7 and FIG. 8 , the first backlight layer 109 and the second backlight layer 110 are integrated, that is, the first backlight layer 109 and the second backlight layer 110 are shared by two display areas. The three backlight layers 111 and the fourth backlight layer 112 are used separately, and the structure is relatively convenient to fabricate.

Secondly, as shown in FIG. 9 and FIG. 10, the first backlight layer 109 and the second backlight layer 110 of the two display regions are separately present and used, that is, the first backlight layer 109 includes the side by side. a backlight film and a second backlight film, the first backlight film and the second backlight film are located in the same plane; the second backlight layer 110 includes a third backlight film and a fourth backlight film arranged side by side, and a third The backlight film and the fourth backlight film are located in the same plane.

There are differences in the structure of the above two methods, but the principle of implementing the display is uniform, and the display principle in each display area can be the same as that in the prior art.

Correspondingly, the third backlight film and the fourth backlight film, and the first backlight film and the second backlight film are respectively disposed on both sides of the thin wall 116.

Since the area of the display screen 101 is small, if the mirror surface is provided only on one side of the display screen 101, when the display area on the side far from the mirror surface is closed, the reflection area is small, which is inconvenient to observe; therefore, as this embodiment In a preferred embodiment, the mirror surface includes a first mirror surface 117 and a second mirror surface 118. The first mirror surface 117 is disposed on a side of the first display area 104 away from the second display area 105, and the second mirror surface 118 is disposed on the first surface. The side of the display area 105 that is away from the first display area 104. The two mirror surfaces are respectively located on both sides of the display screen 101 and correspond to the two display areas.

In order to make the unlit display area and the mirror surface correspond to each other, the first mirror surface 117, the second mirror surface 118, the first display area 104, and the second display area 105 are located in the same plane, and the display effect is very good. More convenient.

Fig. 13 is a schematic view showing the display area of the conventional rear view mirror opened. As shown in Figure 13, the traditional car rearview mirror display is a single-screen display. This display can also display text or graphics in a local or a corner, but because the entire display uses a backlight system, the other displays no text. Or the blank area of the icon still has a certain brightness, so the contrast between the background color of the blank area and the mirror surface is very obvious.

The present invention adopts a multi-window display screen. The present solution is preferably two window displays, which are a first display area 104 and a second display area 105 respectively, and form a complete image when multiple screen windows of the entire display screen are simultaneously displayed. The display of this time is similar to the traditional display. Please refer to Figure 1 for the specific structure.

When one of the windows is closed, referring to FIG. 12, taking the second display area 105 as an example, only the first display area 104 is displayed, thereby realizing partial display, and the backlight strip of the closed second display area 105 is not After the backlight layer is designed, the background color of the second display area 105 is consistent with the background color of the second mirror surface 118, and there is no significant difference. When viewed, the second display area 105 is consistent with the second mirror surface 118. Both are used for reflection, thereby expanding the area of the second mirror surface 118, which is advantageous for expanding the driver's viewing field and reducing safety hazards. When the first display area 104 is turned off and only the second display area 105 is displayed, the first display area 104 is used to enlarge the area of the first mirror surface 117.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
