Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of a display terminal according to a first embodiment of the present invention, where the method is used for the display terminal and includes the following steps:
step S11: and acquiring a target gray scale image of the display terminal.
Step S12: and determining a region to be adjusted in the control regions by using the target gray scale image.
The main execution body of the present invention is a display terminal, the display terminal is installed with a control program of the display terminal, and the display terminal implements the steps of the control method of the display terminal of the present invention when executing the control program of the display terminal.
Generally, the display terminal may be a television, a computer, or the like. The display terminal has a plurality of control regions, and the reference voltage (Vcom) of each control region is controlled individually, and each control region corresponds to one reference voltage. In the conventional approach, the display terminal has only one reference voltage as a whole.
The target gray-scale image can be a gray-scale image corresponding to an interface image acquired by a camera when the display terminal plays any one pure-color picture. In the target grayscale image, there may be areas with non-uniform brightness, and usually, the areas with non-uniform brightness are the areas to be adjusted.
The uneven-luminance region may be a portion of the display terminal where the display luminance is higher than other regions (the high-luminance portion is small), or may be a portion of the display terminal where the display luminance is lower than other regions (the low-luminance portion is small).
Step S13: and obtaining an adjustment reference voltage of the area to be adjusted according to the target gray scale image, wherein the adjustment reference voltage is a fixed value.
It can be understood that the reference voltage referred to in the present invention refers to the reference voltage Vcom in the prior art, and the adjustment reference voltage refers to the reference voltage of the region to be adjusted.
Generally, if the area to be adjusted is a low-brightness control area, the adjustment reference voltage needs to be higher than the original reference voltage (the reference voltage of the area to be adjusted corresponding to the target grayscale image), and if the area to be adjusted is a high-brightness control area, the adjustment reference voltage needs to be lower than the original reference voltage (the reference voltage of the area to be adjusted corresponding to the target grayscale image).
In some embodiments, all the control areas are to-be-adjusted areas, and meanwhile, for the control area with high brightness, the adjustment reference voltage is lower than the original reference voltage, and for the control area with low brightness, the adjustment voltage is higher than the original reference voltage. That is, in this embodiment, each control region corresponds to one adjustment reference voltage. Generally, each control region is a rectangular region with equal area, and the larger the number of control regions, the better the brightness uniformity when the display control is performed by the method of the present invention.
Further, the step of obtaining the adjustment reference voltage of the region to be adjusted according to the target grayscale image includes: and determining the adjustment reference voltage of the area to be adjusted in a preset reference voltage interval according to the target gray scale image.
The reference voltage Vcom is impossible to be randomly adjusted, and can be adjusted only within a range, where the range is a preset reference voltage interval, and the preset reference voltage interval may be an interval composed of a maximum reference voltage Vcommax and a minimum reference voltage Vcommin when the display terminal is in operation, that is, the preset reference voltage interval is [ Vcommin, Vcommax ].
In specific application, generally, a professional technician determines an optimal adjustment reference voltage based on an actual target gray-scale image of the display terminal according to the method of the present invention, and then sets the adjustment reference voltage as a default parameter of the display terminal. The user can carry out adaptive adjustment based on the requirement in practical application: when a user uses the display terminal, the display terminal is also required to output a pure-color image, then the user manually adjusts the reference voltage of each control area, and the display terminal outputs an image corresponding to the adjusted reference voltage of each control area in real time, so that the user can determine whether to continue adjustment.
Step S14: and performing display control on the area to be adjusted by using the adjustment reference voltage.
When the area to be adjusted is a certain control area or a plurality of control areas, the corresponding adjustment reference voltage is used for carrying out display control on the area to be adjusted; and when the areas to be adjusted are all the control areas, controlling each control area by using the adjustment reference voltage corresponding to each control area.
Further, the display terminal further includes a plurality of reference voltage lines, one reference voltage line being connected to one control region; the step of performing display control on the region to be adjusted by using the adjustment reference voltage includes: and displaying and controlling the area to be adjusted by using the adjusting reference voltage through a reference voltage line connected with the area to be adjusted.
Each control area of the display terminal is connected through a corresponding reference voltage line, and different control areas are connected through different reference voltage lines, so that the independent control of different control areas is realized.
Further, the display terminal further comprises a power management integrated circuit; the power management integrated circuit is connected with the control areas through the reference voltage lines; the step of performing display control on the region to be adjusted by using the adjustment reference voltage through a reference voltage line connected to the region to be adjusted includes: and the power management integrated circuit utilizes the adjustment reference voltage to carry out display control on the area to be adjusted through a reference voltage line connected with the area to be adjusted.
Referring to fig. 3-4, fig. 3 is a schematic structural diagram of a display terminal according to a second embodiment of the present invention, and fig. 4 is a schematic structural diagram of a display terminal according to a third embodiment of the present invention.
In fig. 3, the display terminal includes 8 control regions (black bold frame) 11, 8 reference voltage lines (dashed lines) 12, 2 COF13 (chip on film, one on the left and right, and the COF on the right for connecting to other lines) two XB boards 14 (one on the left and right), a TCON board 15, a power Management integrated circuit pmic (power Management ic)16 and a motherboard 17, wherein the power Management integrated circuit is connected to the control regions via the reference voltage lines, and has 8 control regions and 8 reference voltage lines (power Management ic) in total.
Further, the display terminal further comprises a power management integrated circuit and a gamma buffer; the power management integrated circuit is connected with the gamma buffer, and the gamma buffer is connected with the control regions through the reference voltage lines; the step of performing display control on the region to be adjusted by using the adjustment reference voltage through a reference voltage line connected to the region to be adjusted includes: the power management integrated circuit sends the adjustment reference voltage to the gamma buffer so that the gamma buffer sends the adjustment reference voltage to the area to be adjusted through a reference voltage line connected with the area to be adjusted to perform display control on the area to be adjusted. And after the area to be adjusted receives the adjustment reference voltage, the adjustment reference voltage is utilized to control the display panel.
In this embodiment, a gamma buffer is added; referring to FIG. 4, a gamma buffer (P-gamma IC)18 is added.
Further, the display terminal further comprises a chip on film; the reference voltage lines are connected with the control areas through the chip on film.
In this embodiment, each Chip On Film (COF) may be connected to a plurality of reference voltage lines, and referring to fig. 3, one COF is connected to 8 reference voltage lines, and the other COFs are not used for connection of the reference voltage lines.
Furthermore, the chip on film comprises a plurality of reference voltage lines, and one reference voltage line is connected with one control area through one chip on film.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a control process of a display terminal according to the present invention; in fig. 5, a schematic diagram of a control process of a display terminal in the prior art is shown above a thick horizontal dotted line, and a schematic diagram of a control process of a display terminal in the present invention is shown below the thick horizontal dotted line.
First, in the prior art, for the gray-scale picture, the VCOM voltage is a whole plane (in fig. 5, the thick solid line of the schematic diagram of the control process of the display terminal in the prior art), only a fixed voltage needs to be given, and the gray-scale picture Data level is switched once per frame, for example, in fig. 5, the 1 st frame Data waveform is a positive frame, the deflection voltage loaded across the liquid crystal is V1 ═ Data-VCOM, the 2 nd frame is a negative frame, the deflection voltage loaded across the liquid crystal is V2 ═ VCOM-Data, and the process is repeated. The pressure difference loaded on two ends of the liquid crystal in the previous frame and the next frame is different only in direction and is the same in size. Since human eyes cannot sense the change of one frame, the prior art as shown in the figure can normally display gray scale pictures, and the gray scales are related to the high level of Data.
In fig. 5, no process is performed on the brightness unevenness of the area of the display terminal, and thus a bright area and a dark area may occur.
In the present invention, in the lower diagram of the display terminal control process of the present invention in fig. 5, the bright area and the dark area are pulled out by one VCOM respectively, and the VCOM, i.e. VCOM1 voltage corresponding to the bright area positive frame is increased, the VCOM, i.e. VCOM2, corresponding to the dark area positive frame is decreased, the VCOM1 corresponding to the a area negative frame is decreased, and the negative frame VCOM2 corresponding to the B area is increased. Through the compensation in the mode, the voltage difference between the Data and the VCOM is different according to different areas, so that the brightness of the panel can be adjusted according to the areas, and the problem of uneven area brightness is solved.
The technical scheme of the invention provides a control method of a display terminal, which is used for the display terminal with a plurality of control areas; the method comprises the following steps: acquiring a target gray scale image of the display terminal; determining a region to be adjusted in the control regions by using the target gray scale image; obtaining an adjustment reference voltage of the area to be adjusted according to the target gray scale image, wherein the adjustment reference voltage is a fixed value; and performing display control on the area to be adjusted by using the adjustment reference voltage.
In the existing method, the compensation Data needs to be calculated, the Data voltage is a real-time changing value, so that the compensation Data needs to include corresponding compensation values of the region to be adjusted under different Data voltages, and thus, the calculation process of the compensation Data takes a large amount of time and calculation power, which results in high cost of obtaining the compensation Data of the display terminal and high cost of the display terminal.
