Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a liquid crystal display device according to an embodiment of the present application.
As shown in fig. 1, the liquid crystal display device 100 of the present embodiment includes: a backlight 10, a liquid crystal display panel 20 and a light guide device 40.
The backlight plate 10 is provided with a through hole 14. In one embodiment, the backlight 10 may include a reflective sheet 11, a light guide plate 12, and an optical module 13, and may further include a light source 15, where the light source 15 may be a common side light source.
In one embodiment, the liquid crystal display panel 20 includes a light transmissive region 101 and a display region 102; at least the light-transmitting area 101 is not provided with a color resistance; wherein the light-transmitting area 101 is used for arranging a functional module. The backlight plate 10 corresponds to the display region 102, and the through hole 14 corresponds to the light-transmitting region 101; in one embodiment, the liquid crystal display panel 20 may include, from bottom to top, a first polarizer 21, an array substrate 22, a liquid crystal layer 23, a color filter substrate 24, and a second polarizer 25.
The first color light source 41 is a field sequential light source. In one embodiment, when the light-transmitting region 101 is in the display state, the first color light source 41 is turned on to display a picture; when the light-transmitting region 101 is in a light-transmitting state, the first color light source 41 is turned off, so that external light is transmitted to the functional module through the light-transmitting region.
The position of the light guide element 42 corresponds to the position of the light-transmitting area 101; the light guide element 42 is used for converting the light provided by the first color light source 41 into a surface light source for the light-transmitting region. In one embodiment, to improve the display effect, the area of the orthographic projection of the light guide element 42 on the set plane is greater than or equal to the area of the orthographic projection of the through hole 14 on the set plane. The setting plane can be a plane on which the liquid crystal display panel is located.
In one embodiment, in order to further reduce interference with the functional module, the light guide element 42 is disposed below the through hole 14, and the first color light source 41 is disposed on a side surface of the light guide element 42.
In one embodiment, in order to improve the stability of the color light source, as shown in fig. 2, the light guide element 42 includes a main body 421 and an extension 422, the extension 422 is disposed outside one end of the main body 421, the thickness of the extension 422 is smaller than that of the main body 421, and the first color light source 41 is fixed on the extension 422. In other embodiments, a groove (not shown) is provided on a sidewall of the light guide element 42, and the first color light source 41 is fixed in the groove. Of course, it is understood that the fixing manner of the first color light source 41 is not limited thereto.
When the light-transmitting area 101 is in the display state, the first color light source 41 is turned on, and the light guide element 42 is in the fog state;
when the light-transmitting region 101 is in a light-transmitting state, the first color light source 41 is turned off, and the light guide element 42 is in a transparent state.
In an embodiment, the display device may further include a light shield 30. The light shielding plate 30 is disposed on an inner sidewall of the through-hole 14. The light shielding plate 30 is used to block the light of the backlight plate 10, so as to prevent the light of the backlight plate from interfering with the functional module. The light shielding plate 30 of the present embodiment may cover the entire inner sidewall of the through hole.
In another embodiment, the display area 102 is also not provided with color resists, and the light source 15 is a second color light source for providing light to the backlight board 10; when the light-transmitting region 101 is in the display state, the first color light source 14 and the second color light source 15 are driven in synchronization.
The second color light source 15 is a field sequential light source, and the second color light source 15 is disposed on a side of the backlight 10 away from the through hole 14. In one embodiment, in order to improve the stability of the second color light source, the reflective sheet also includes an extension portion 111 and a main body portion 112, the extension portion 111 is disposed outside one end of the main body portion 112, and the second color light source 15 is fixed on the extension portion 111. It will be appreciated that the manner of fixing the second colored light sources 15 is not limited thereto.
In the specific working process, the light guide element 42 can be switched between a transparent state and a fog state by applying voltages with different magnitudes to the light guide element 42, when the light guide element is in the fog state, the first color light source 41 is turned on, light entering through the side of the light guide element 42 can be scattered, backlight light can be provided for a light transmission area above the light guide element, the light transmission area can also display normally at the moment, the functional module is arranged below the light transmission area, and the backlight brightness and the scattering intensity of the light guide element 42 can be controlled by the voltages of the first color light source 41 and the light guide element 42 respectively. When the light guide element 42 is switched to the transparent state, the first color light source 41 is turned off, and at this time, the external light passes through the light transmission region and enters the functional module, and the functional module can normally operate.
In this driving method, the refresh rate of the first color light source 41 and the refresh rate of the second color light source 15 are synchronized with the refresh rate of the liquid crystal display panel 20, so that normal screen display can be performed. Therefore, the first color light source 41 and the second color light source 15 are driven in synchronization, and driving signals of both may be provided through the FPC or the main board.
When the function module is turned on, the first color light source 41 is in an off state and the light guide element 41 is in a transparent state, and when the function module is turned off, the first color light source 41 is in an on state and the light guide element 41 is in a fog state, so as to scatter light.
Because the field sequential light source is arranged in the light transmission area, the picture display of the light transmission area can be realized through the field sequential light source when the functional module does not work, and the display effect is improved. In addition, since the color resistance layer is not arranged in the display panel of the light-transmitting area, the aperture ratio and the transmittance of the light-transmitting area are improved.
Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a liquid crystal display device according to another embodiment of the present application.
As shown in fig. 3, the liquid crystal display device of the present embodiment is different from the first embodiment in that: the first color light source 41 of the present embodiment is an oled tri-color light source, which may include a red light, a green light and a blue light.
In one embodiment, in order to further reduce interference with the functional module, the through hole 14 includes a first sub-hole 141 and a second sub-hole 142, the first sub-hole 141 is disposed on the light guide plate 12 and the optical film 13, the second sub-hole 142 is disposed on the reflective sheet 11, and a width of the second sub-hole 142 is smaller than a width of the first sub-hole 141; wherein the width of the first sub-hole 141 is close to the width of the light-transmitting region 101;
the reflector 11 comprises an inward extending portion 113, the inward extending portion 113 is located in the light-transmitting region 101, and the inward extending portion 113 is disposed at two sides of the second sub-hole 142; the first color light source 41 is arranged on the inward extending part 113; the light guide element 42 is disposed on the first color light source 41. Referring to fig. 4, in a top view, the first color light source 41 is disposed at the periphery of the first sub-aperture 142, or surrounds the periphery of the first sub-aperture 142.
In one embodiment, in order to reduce interference of the light guide element with the functional module, the light shielding plate 30 covers an inner sidewall of the first sub-hole 141, and the light guide element 42 also covers an end portion of the inward extending portion 113 near the second sub-hole 142.
In another embodiment, the liquid crystal display device of the present embodiment is different from the second embodiment in that: the second color light source 15 is an organic light emitting diode three-color light source, and the second color light source 15 is disposed on the reflective sheet 11.
The same data is sent in the display area except the light transmission area 101 within 3 frames, and the picture is kept; the light-transmitting area 101 sequentially lights the red light, the green light and the blue light in 3 frames to display 3 colors of R ', G' and B ', and data R' G 'B' in the three-frame area are overlapped to form a complete picture for display through the short stay of human vision.
The frame refresh frequency of the image data unit is, for example, 120Hz, that is, the display area synchronously sends RGB data with a period of 8.33ms, but the RGB data sent every three frames are the same, the light-transmitting area 101 cyclically lights the lamps of each color of the three-color lamps with a period of 8.33ms to display three colors of R ', G', and B ', that is, three colors of red, green, and blue, the R' G 'B' data are superimposed to realize the display of the picture by the short stay of human vision, the image superimposition needs 25ms, which is equivalent to updating a complete picture in three frames, wherein the frame refresh rate is not limited to 120 Hz.
Because set up organic emitting diode three-colour light source in the printing opacity region, therefore can realize the regional picture display of printing opacity through controlling three-colour light source when functional module is out of work, improved display effect.
The operation principle of this embodiment is the same as that of the first embodiment.
Referring to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure.
In an embodiment, the electronic device 200 may include the liquid crystal display device 100 and the functional module 50, and the functional module 50 is disposed below the light guide element 42. The functional module comprises at least one of a camera, a fingerprint identification module and a distance sensor.
In another embodiment, as shown in fig. 6, the functional module 50 is disposed below the second sub-hole 142, and the functional module 50 corresponds to the position of the second sub-hole 142. Because the electronic equipment of the embodiment has no other elements above the functional module, the lighting effect of the functional module is better, and the accuracy is improved.
