Detailed Description
The embodiment of the application provides a device, display equipment and a method for enhancing the image brightness, which do not need to control the backlight brightness to enhance the image brightness in a high-brightness state or a sub-high-brightness state, so that the power consumption is reduced compared with the method for controlling the backlight brightness.
As shown in fig. 1, an apparatus for enhancing image brightness according to an embodiment of the present application includes:
the light sensing unit 1 is used for collecting the brightness value of the ambient light;
the determining unit 2 is configured to determine a preset brightness state to which the ambient light belongs according to the brightness value of the ambient light;
and the control unit 3 is configured to determine a corresponding relationship between a gray scale of a pixel corresponding to a preset luminance state to which the ambient light belongs and the driving voltage, and control image display according to the corresponding relationship.
In the device for enhancing the picture brightness, the light sensing unit collects the brightness value of the ambient light, the determining unit determines the preset brightness state of the ambient light according to the brightness value of the ambient light, the control unit determines the corresponding relation between the gray scale of the pixel corresponding to the preset brightness state of the ambient light and the driving voltage, and the picture display is controlled according to the corresponding relation, so that when the ambient light brightness changes, the display picture brightness can be changed only by changing the gray scale driving voltage of the pixel, and compared with the prior art that the display picture brightness is changed by controlling the backlight brightness, the power consumption can be reduced.
Preferably, the preset brightness state specifically includes: dark state, normal state, sub-highlight state, and highlight state. And the ambient light brightness in the dark state, the normal state, the secondary highlight state and the highlight state is increased in sequence. For example, the environmental light brightness ranges in the dark state, the normal state, the sub-highlight state and the highlight state are 0-30 Lux (Lux), 30-100 Lux, 100-500 Lux and 1000-100000 Lux, respectively. The brightness of the display image in the dark state, the normal state, the second highlight state and the highlight state should be increased in sequence, and the display effect of the image in the second highlight state can be enhanced only if the brightness of the display image in the second highlight state is higher than that of the display image in the normal state.
It should be noted that, in the embodiment of the present application, the preset luminance state is divided into four types, and the preset luminance state division may also be divided according to specific situations, which is not limited to the four types of states in the embodiment of the present application.
Preferably, as shown in fig. 2, the determining unit is a photo processor 4.
Preferably, the optoelectronic processor 4 is specifically configured to:
and converting the brightness value of the environment light into a digital signal, comparing the digital signal with the preset brightness state, and determining the preset brightness state of the environment light according to the comparison result.
Preferably, as shown in fig. 3, the control unit includes a gamma integrated circuit 5 and a driving chip 6; wherein,
the gamma integrated circuit 5 is configured to determine multiple sets of data information corresponding to a preset brightness state to which the ambient light belongs, where each set of data information includes a gray scale of a pixel and a voltage value for driving the pixel;
for example, the gamma ic stores a plurality of sets of data information for each preset brightness state in advance, each set including a gray-scale value of a pixel and a corresponding driving voltage value. The multiple sets of data information corresponding to each preset brightness state include gray scales of 8 sets of pixels and voltage values for driving the pixels, and of course, all the gray scales of the pixels and the voltage values for driving the pixels may be stored. Different preset brightness states correspond to different groups of data information, that is, under different environment light brightness states, the same gray scale of any pixel corresponds to different voltage values for driving the pixel, so that different display brightness corresponding to the same gray scale of the pixel under different environment light brightness states can be realized, and different control of display image brightness under different environment light brightness states can be realized.
The driving chip 6 is configured to determine a corresponding relationship between the gray scale of the pixel and the driving voltage according to the multiple sets of data information, and control the display of the image according to the corresponding relationship and the gray scale of each pixel of the image to be displayed.
Preferably, the gamma ic 5 includes a plurality of storage units, each of which stores a plurality of sets of the data information corresponding to a preset brightness state;
as shown in fig. 4, the relationship between the gray scale of a pixel stored in a memory unit and the voltage value for driving the pixel can be represented by a Gamma (Gamma) correction curve, in which the abscissa is the gray scale value of the pixel and the ordinate is the normalized value of the driving voltage corresponding to different gray scale values. In the gamma integrated circuit 5, different storage units store multiple sets of data information corresponding to different preset brightness states, that is, the relationship between the gray scale of a pixel in different preset brightness states and the voltage value for driving the pixel is represented by different gamma curves; in the figure, four Gamma curves of Gamma1.9, Gamma 2.0, Gamma 2.2 and Gamma 2.5 correspond to four preset brightness states, and 1.9, 2.0, 2.2 and 2.5 represent the identifications of the Gamma curves, which satisfy the relationship between the gray scale of the pixel and the voltage value for driving the pixel in different preset brightness states stored in the storage unit. For example, as shown in fig. 4, voltages corresponding to the same gray scale value of different Gamma curves are different, and the same gray scale value, for example, when the gray scale value is a, the voltage in the Gamma1.9 curve is higher than the voltage in the Gamma 2.0 curve, and accordingly, if the display luminance control is performed by using the correspondence relationship between the gray scale of the pixel represented by the Gamma1.9 curve and the driving voltage for the same pixel of the same screen, the display luminance is higher than that by performing the display luminance control by using the correspondence relationship between the gray scale of the pixel represented by the Gamma 2.0 curve and the driving voltage, and thus, the luminance of the display screen can be effectively enhanced by outputting the data information corresponding to the Gamma1.9 curve compared with outputting the data information corresponding to the Gamma 2.0 curve.
Optionally, the multiple sets of data information stored in each storage unit include gray scales of 8 sets of pixels and voltage values for driving the pixels; the 8 sets of data information stored in each memory cell may be, as shown in fig. 4, the gray scales a, b, c, d, e, f, g, and h of the pixels in the gamma curve corresponding to the memory cell and the driving voltages corresponding thereto.
The determining unit is specifically configured to: determining a preset brightness state to which the ambient light belongs according to the brightness value of the ambient light, and sending an addressing control signal corresponding to the preset brightness state to which the ambient light belongs to the gamma integrated circuit 5;
the gamma integrated circuit 5 outputs a plurality of groups of data information in the storage unit corresponding to the addressing control signal to the driving chip 6.
When the preset brightness state of the ambient light changes, the addressing control signal output by the determining unit changes correspondingly, so as to control the gamma integrated circuit 5 to address different memory cells and output corresponding data information. For example, when the determining unit determines that the ambient light belongs to a sub-highlight state, the determining unit sends an addressing control signal of the sub-highlight state to the gamma integrated circuit, the addressing control signal controls a storage unit, which stores data information of the sub-highlight state, in the gamma integrated circuit to output gray scales of 8 groups of pixels corresponding to the sub-highlight state and voltage values of driving pixels to the driving chip 6, the driving chip determines a corresponding relationship between the gray scales of the pixels and the voltages of the driving pixels according to the received gray scales of the 8 groups of pixels and the voltage values of the driving pixels, and determines corresponding driving voltages according to the corresponding relationship and the gray scales of each pixel of a picture to be displayed, and controls picture display.
Because the gamma integrated circuit outputs the data information in real time, the response speed is high, and the output data information can be changed immediately as long as the addressing control signal changes the address bit.
Based on the same idea, an embodiment of the present application provides a display device including the above-mentioned device for enhancing the brightness of a picture.
As shown in fig. 5, when the ambient light brightness changes, the specific operation process of the device for enhancing the image brightness is as follows:
s501, collecting the brightness value of the ambient light by a light sensing unit, and sending the brightness value of the current ambient light to a photoelectric processor;
s502, the photoelectric processor determines a preset brightness state of the ambient light according to the brightness value of the ambient light sent by the light sensing unit, and sends an addressing control signal corresponding to the preset brightness state of the ambient light to the gamma integrated circuit;
s503, the gamma integrated circuit outputs a plurality of groups of data information in the storage unit corresponding to the addressing control signal to the driving chip;
s504, the driving chip determines the corresponding relation between the gray scale of the pixel and the driving voltage according to the multiple groups of data information, and controls the display of the picture according to the corresponding relation and the gray scale of each pixel of the image to be displayed.
An embodiment of the present invention provides a method for enhancing image brightness, as shown in fig. 6, including:
s601, collecting the brightness value of the ambient light;
s602, determining a preset brightness state of the ambient light according to the brightness value of the ambient light;
s603, determining the corresponding relation between the gray scale of the pixel corresponding to the preset brightness state of the ambient light and the driving voltage, and controlling the picture display according to the corresponding relation.

Preferably, determining the preset brightness state to which the ambient light belongs according to the brightness value of the ambient light specifically includes:
and converting the brightness value of the environment light into a digital signal, comparing the digital signal with the preset brightness state, and determining the preset brightness state of the environment light according to the comparison result.
