Referring to fig. 1 to 7, fig. 1 is a first structural schematic diagram of a display device according to the present invention.
As shown in fig. 1 and 2, the display device of the present invention includes a display screen 10 and a backlight module 20, and the display screen 10 includes a light-transmitting area 101 and a display area 102.
The backlight module 20 is provided with a region control assembly 30, the region control assembly 30 corresponds to the position of the light-transmitting region 101, and the region control assembly 30 comprises a three-color lamp 31 and a light guide member 32; the light guide member 32 is disposed above the three-color lamp 31. In one embodiment, to further improve the effect, the three-color lamp 31 is a three-color lamp ring, and the light guide member 32 is a light guide ring.
The backlight module 20 includes a back plate (not shown), a groove 211 is formed on the back plate, and the area control assembly 30 is embedded in the groove 211. Of course, a base 40 may be disposed under the backlight module 20, and the bottom of the area control assembly 30 is fixed on the base 40.
Referring to fig. 3 and 4, the back plate 20 includes a first sub-portion 21 and a second sub-portion 22, the first sub-portion 21 corresponds to the display region 102, and the second sub-portion 22 corresponds to the light-transmitting region 101.
In an embodiment, the first sub-portion 21 has a plurality of micro light emitting diodes 23, that is, the structure of the backlight module corresponding to the display area 102 includes a back plate and a plurality of micro light emitting diodes 23 disposed on the back plate. In another embodiment, the first sub-portion 21 is provided with a light guide plate, an optical film, a light source, and the like, that is, the backlight module corresponding to the display region 102 may have a conventional structure, and the backlight module corresponding to the light-transmitting region 101 is provided with the region control assembly 30.
As shown in fig. 5, the display device further includes a camera 50, a position of the camera 50 corresponds to a position of the light-transmitting area 101, and the light-transmitting area 101 covers the camera 50.
The present invention also provides a driving method of a display device including:
s101, inputting a plurality of image data units to the display area, wherein each frame of image data unit comprises three frames of same image data;
as shown in fig. 6, a plurality of image data units 201 are input to the display area 102, each image data unit 201 including three frames of the same image data D1-D3.
For example, each frame of image data includes red data R, green data G, and blue data B. Where 201 denotes a waveform of a single image data unit input to the display region 102, 202 denotes a waveform of an equivalent display image of the light-transmitting region 101, and 203 denotes a waveform of a data signal input to the data chip, or a waveform of a data signal input to the display region 102, the data signal including red data R, green data G, and blue data B.
S102, lighting the three-color lamps, wherein the lighting frequency of the lamps with various colors in the three-color lamps is consistent with the frame refreshing frequency of each frame of image data in the image data unit; and the lighting time of the lamp of each color in the three-color lamp is consistent with the input time of each frame of image data in the image data unit.
For example, where the three-color lamp includes lamps 311 and 313 of three colors of red, green and blue, taking a red lamp as an example, the lighting frequency of the red lamp 311 is consistent with the frame refresh frequency 1/T1 of the first frame image data D1; that is, the lighting period (the cycle of R') of the red lamp 311 coincides with the cycle T1 of the first frame image data D1; and the lighting time t0 of the red lamp 311 coincides with the input time of the first frame image data D1, i.e., both are input in synchronization. It is understood that the green lamps 312 and the blue lamps 313 are illuminated in a manner similar to that of the red lamps 311. In one embodiment, T1, T2, and T3 are all equal, such as all equal to 8.33 ms.
The lighting time of each color lamp in the three-color lamp is consistent with the display time of the image data of the corresponding frame. For example, the lighting period T4 of the red lamp 311 coincides with the display period (period in which R' is high level) of the first frame image data. For example, the lighting period T5 of the green lamp 312 coincides with the display period (period in which G' is high level) of the second frame image data. For example, the lighting period T5 of the blue lamp 313 coincides with the display period (period in which B' is high) of the third frame image data.
The lighting time of each color lamp in the three-color lamp is longer than the input time of the image data of the corresponding frame. That is, taking the red data as an example, the lighting time period T2 of the red lamp is longer than the input time period T7 of the red data R, the red data R is input only during the period T7, and the display region 102 maintains the current image data during the periods T7 to T4. The blue data B and the green data G are similar thereto.
The lighting time periods of the lamps of each color are equal, that is, the lighting time period T4 of the red lamp 311, the lighting time period T5 of the green lamp 312, and the lighting time period T6 of the blue lamp 313 are equal.
As shown in fig. 7, the same data is transmitted to the display area other than the light-transmitting area 101 within 3 frames to keep the screen; 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 the tricolor lamp in the light transmission region, therefore can realize the regional picture of light transmission and show through controlling the tricolor lamp when the camera is out of work, improved display effect.
The display device and the driving method thereof comprise a display screen, a light-transmitting area and a display area, wherein the display screen comprises the light-transmitting area and the display area; the backlight module is provided with an area control assembly, the position of the area control assembly corresponds to that of the light transmission area, and the area control assembly comprises a three-color lamp and a light guide piece; the light guide piece is arranged above the three-color lamp; because set up the tricolor lamp in the light transmission region, therefore can realize the regional picture of light transmission and show through controlling the tricolor lamp when the camera is out of work, improved display effect.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
