[0002] As display panels become larger, resolutions increase, and dual-layer panel technology matures, 2D / 3D switchable display devices are becoming increasingly widespread in practical applications.

[0003] Currently, display devices typically employ a slit-type solution with dual-layer panels to switch between 2D and glasses-free 3D display modes. When displaying in 2D, the image resolution remains unchanged; when displaying in glasses-free 3D, the outer panel of the display device appears as a black raster, blocking some light and creating a difference in the amount of light entering the left and right eyes, thus achieving the glasses-free 3D effect.

[0107] Currently, display devices typically use a slit-type solution with a double-layer panel to switch between 2D and glasses-free 3D display modes. Figure 4 This is a schematic diagram illustrating the principle of implementing glasses-free 3D using a double-layer panel according to an embodiment of this application, as shown below. Figure 4As shown, the dual-layer panel includes an inner panel 401 (which can be understood as an LCD panel) and an outer panel 402 (which can be understood as a raster panel). When performing naked-eye 3D display, the outer panel 402 of the display device displays a black raster, which blocks some of the light, so that the light entering the left and right eyes is different. That is, the left eye and the right eye obtain different images corresponding to the left eye and the right eye, thereby realizing the naked-eye 3D display effect. The outer panel 402 is a liquid crystal panel without a color filter.

[0108] In some application scenarios, for LED display devices that can be controlled in zones, it is necessary to display some areas in naked-eye 3D and some areas in 2D. The backlight of the display device is, for example, a direct-lit LED solution, with each or several LEDs forming a display unit. The current value of each display unit can be independently controlled by the LED control driver. Figure 5 The diagram illustrates a partial area of ​​the display in naked-eye 3D and a partial area of ​​the display in 2D, as provided in an embodiment of this application. Figure 5 As shown, the display area is divided into a 2D display area and a glasses-free 3D display area. The display area may also contain multiple 2D display areas and multiple glasses-free 3D display areas; this application does not specifically limit this. The grating panel area corresponding to the glasses-free 3D display area is in 3D working state, that is, periodically turning off some sub-pixels or pixels to form a black and white grating structure. The grating panel area corresponding to the 2D display area is in 2D working state, that is, fully open state.

[0109] In glasses-free 3D display areas, due to the absorption effect of the black grating, only unabsorbed light enters the human eye, resulting in a reduction in the actual image brightness. Assuming the area of ​​a single period is S0 and the area of ​​the black grating is S1, the image brightness is reduced to [a fraction of the original brightness]. That is, the brightness ratio of the corresponding displayed image is At this point, noticeable differences in brightness will appear within the same image, indicating an inconsistency in brightness across the entire display. This significantly reduces viewing comfort for the human eye, and if the brightness reduction from the black raster is too low, it may even make it impossible to clearly see the displayed content.

[0110] To address the aforementioned issues, this application provides a display device and control method that increases the backlight brightness of the naked-eye 3D display area and decreases the backlight brightness of the 2D display area by adjusting the regional light control of the LEDs. This ensures that the brightness of the naked-eye 3D display area and the 2D display area remains consistent, i.e., the brightness of the entire display screen remains consistent. Therefore, it can improve the image quality of the display device and enhance the user experience.

[0111] The following detailed embodiments illustrate how this application performs control.

[0112] Figure 6A flowchart illustrating a control method provided in one embodiment of this application is shown. This method is applied to a display device, which includes a display and a processor connected to the display. Figure 6 As shown, the processor in the display device is configured to perform the following steps:

[0113] In S601, in response to an instruction to perform naked-eye 3D display in the target display area of ​​the display, the LED area corresponding to the target display area is determined.

[0114] The target display area is a portion of the display area of ​​the monitor.

[0115] In this embodiment of the application, by way of example, reference is made to Figure 5 The display area of ​​the monitor is divided into a 2D display area and a glasses-free 3D display area, where the glasses-free 3D display area is the target display area. In this step, in response to the instruction to perform glasses-free 3D display in the target display area of ​​the monitor, the LED area corresponding to the target display area can be determined.

[0116] Further, optionally, determining the LED region corresponding to the target display area may include: determining the size of the target display area based on the number of pixels and pixel size of the target display area; determining the number of LEDs contained in the LED region based on the size of the target display area, the position of the center point of the target display area, and the size of the display unit, wherein the display unit includes at least one LED; and determining the LED region based on the number of LEDs and the spacing between the LEDs.

[0117] For example, Figure 7 The diagram illustrates, for another embodiment of this application, partial areas of naked-eye 3D display and partial areas of 2D display, as shown below. Figure 7 As shown, based on Figure 5For example, when a portion of the display panel needs to be used for glasses-free 3D display, the raster state of the corresponding raster panel is switched to glasses-free 3D display mode (i.e., periodically turning off the display of sub-pixels or pixels, corresponding to periodic slit raster). The image signal input to the display panel, in the glasses-free 3D display area, is processed image content containing differences between the left and right eyes, while in the 2D display area, it remains ordinary 2D image content. Assuming the number of pixels in the glasses-free 3D display area is represented by M×N, where M represents the number of rows of pixels in the glasses-free 3D display area, and N represents the number of columns of pixels in the glasses-free 3D display area, and the pixel size of the glasses-free 3D display area is represented by D×D, where D represents the side length of the pixel, then the size of the glasses-free 3D display area (i.e., the size of the target display area) can be determined as MD×ND. Therefore, based on the size of the target display area, the position of the center point of the target display area, and the size of the display unit, the number of LEDs contained in the LED area can be determined. This number of LEDs can be represented, for example, by P×Q (i.e., PQ), where P represents the number of rows of LEDs contained in the LED area, and N represents the number of columns of LEDs contained in the LED area. Assuming the LED spacing is represented by L×F, where L represents the row spacing between two adjacent LEDs and F represents the column spacing between two adjacent LEDs, then the size of the LED region is (P-1)×L×(Q-1)×K, and (P-1)×L≥MD, (Q-1)×K≥ND. This allows us to obtain... Figure 7 The target display area shown corresponds to the LED area.

[0118] In S602, the current of the LEDs in the LED area is increased and the deflection of the liquid crystal molecules in the adjacent display areas of the target display area is decreased to adjust the brightness of the images corresponding to the target display area and the adjacent display areas.

[0119] Among these methods, the radius of the light spot produced by the LED after increasing the current can be used to determine the adjacent display areas.

[0120] For example, suppose the display area of ​​the monitor contains G×H (i.e., GH) LEDs, where G represents the number of rows of LEDs in the display area and H represents the number of columns of LEDs in the display area. If the target display area contains P×Q LEDs, then increasing the current to the P×Q LEDs will correspondingly increase the brightness of the corresponding display area. Assuming the brightness of the LED area corresponding to the target display area is L when displaying a 2D image... 2D The corresponding LED current is represented by I. 2D It means that, among them, L 2D and I 2D These are all the default values ​​for the LEDs at the factory; when the LED area corresponding to the target display area is displaying a 3D image, its brightness will be reduced due to the grating effect, for example, using L... 3DThis indicates that, based on the brightness ratio of the image displayed in the naked-eye 3D display area in the above embodiments, it is possible to obtain...

[0121] To ensure that the brightness of the image displayed in the LED area corresponding to the target display area is not significantly different from the brightness of the image displayed in adjacent display areas (i.e., the brightness of the 3D image reaches the brightness of the previous 2D image), the current of the LEDs in the LED area corresponding to the target display area needs to be increased. The increased current can be obtained using the following formula:

[0122]

[0123] Among them, I 3D This represents the increased current; K represents the coefficient relating brightness and current, which is determined based on the characteristics of the LED itself.

[0124] For details on how to increase the current of the LEDs within the LED area, please refer to subsequent embodiments; details will not be repeated here. After increasing the current of the LEDs within the LED area corresponding to the target display area, the brightness of adjacent display areas between the target display area and the 2D display area will exhibit localized high brightness due to the influence of the increased current on the LEDs. To eliminate the high brightness effect in adjacent display areas, compensation processing of the display panel is required, i.e., controlling the degree of deflection of liquid crystal molecules in adjacent display areas to reduce the light transmittance of adjacent display areas. The adjacent display areas are determined based on the radius of the light spot generated by the LEDs after adjusting the current. For example, refer to... Figure 7 LEDs with increased current (corresponding to) Figure 7 Let R1 represent the radius of the light spot (of the black square in the image). Any location within a straight-line distance of R1 from the LED plane will be illuminated by the LED, resulting in a corresponding increase in brightness. Therefore, it can be determined that... Figure 7 The adjacent display areas of the naked-eye 3D display area are shown. For details on how to reduce the deflection of liquid crystal molecules in the adjacent display areas of the target display area, please refer to subsequent embodiments; they will not be repeated here.

[0125] The control method provided in this application, in response to an instruction to perform naked-eye 3D display in the target display area of ​​the display, determines the LED area corresponding to the target display area; increases the current of the LEDs contained in the LED area and decreases the deflection degree of the liquid crystal molecules in the adjacent display areas of the target display area, thereby adjusting the brightness of the screen corresponding to the target display area and the adjacent display areas. Since this application adjusts the brightness of the backlight by adjusting the current of the LEDs contained in the naked-eye 3D display area, and simultaneously considers the influence of the LEDs contained in the naked-eye 3D display area after the current adjustment on the adjacent display areas, it adjusts the deflection degree of the liquid crystal molecules in the adjacent display areas to achieve consistent brightness between the naked-eye 3D display area and the 2D display area, i.e., consistent brightness across the entire display screen, it can improve the image quality of the display device and enhance the user experience.

[0126] Figure 8 A flowchart illustrating a control method provided in another embodiment of this application. Based on the above embodiments, this application further describes the control method. For example... Figure 8 As shown, the processor in the display device is configured to perform the following steps:

[0127] In S801, in response to an instruction to perform naked-eye 3D display in the target display area of ​​the display, the LED area corresponding to the target display area is determined.

[0128] The target display area is a portion of the display area of ​​the monitor.

[0129] The specific implementation process of this step can be found in the relevant description of S601, and will not be repeated here.

[0130] In this embodiment, the maximum current that the LED of the display device can withstand and the maximum output power of the LED's power supply are considered. Figure 6 Step S602 may further include the following seven steps S802 to S808:

[0131] In S802, the first target current of the LEDs in the LED area is determined based on the current current of the LEDs in the LED area, the brightness ratio of the image displayed in the target display area, and the brightness-current relationship coefficient.

[0132] The coefficient relating brightness to current is determined based on the characteristics of the LED itself.

[0133] For example, assuming the current current of the LEDs within the LED region is represented by I1, and the first target current is represented by I2, based on the above formula one, it can be determined that...

[0134] In S803, if the first target current is less than the current threshold and the power consumption of the adjusted display is less than the power threshold, the current of the LEDs in the LED area is increased from the current to the first target current.

[0135] Among them, the current threshold is the maximum current that the LED can withstand, and the power threshold is the maximum output power of the LED's power supply.

[0136] In this step, for example, the current threshold is expressed as I. max This indicates that the power threshold, for example, is represented by P. max Let P2 represent the adjusted power consumption of the display. Based on the first target current I2 obtained in step S802, the adjusted power consumption of the display can be determined as P2 = (GH - PQ)·I1·V1 + PQ·I2·V2, where GH represents the number of LEDs (G×H) in the display area, PQ represents the number of LEDs (P×Q) in the LED area corresponding to the target display area, and V1 and V2 are the voltages of the LEDs when the currents are I1 and I2, respectively. If I2 < I... max And P2 < P max Then the current of the LEDs in the LED area will be adjusted from the current to the first target current I2. Figure 9 This is a schematic diagram of the backlight brightness curve corresponding to the current of the LEDs in the adjusted LED area provided in one embodiment of this application, as shown below. Figure 9 As shown, the backlight brightness curve distribution is shown before adjusting the current of the LEDs in the LED area, that is, when the current of the LEDs in the LED area is the current I1. The backlight brightness curve can be understood as the original backlight brightness curve. Figure 10 This is a schematic diagram of the backlight brightness curve corresponding to the adjustment of the current of the LEDs included in the LED area according to an embodiment of this application, as shown below. Figure 10 As shown, the backlight brightness curve distribution is shown after adjusting the current of the LEDs in the LED area, that is, when the current of the LEDs in the LED area is the first target current I2. The backlight brightness curve can be understood as the new backlight brightness curve.

[0137] In S804, if the first target current is greater than or equal to the current threshold and the power consumption of the adjusted display is less than the power threshold, the current of the LEDs contained in the LED area is increased from the current current to the current threshold; and a second target current is determined based on the current threshold, the current current and the brightness-current relationship coefficient; and the current of the LEDs contained in the two-dimensional display area is reduced to the second target current.

[0138] For example, based on the example of step S803, the adjusted power consumption of the display can be determined as P2 = (GH - PQ)·I1·V1 + PQ·I2·V2, if I2 ≥ I max And P2 < P max Then the current of the LEDs in the LED region will be adjusted from the current current to the current threshold I. max The current of the LEDs within the LED region is adjusted from the current to a current threshold I. max Afterwards, although the brightness of the naked-eye 3D display area is improved, it is still lower than that of the 2D display area. To maintain equal brightness in the displayed image, the current of the LEDs in the 2D display area needs to be appropriately reduced. This can be done based on the current threshold I. max The current I1 and the brightness-current relationship coefficient K are used to determine the second target current. After determining the second target current, the current of the LEDs contained in the two-dimensional display area is reduced to the second target current.

[0139] Further, optionally, determining the second target current based on the current threshold, the current, and the brightness-current relationship coefficient may include: determining the backlight brightness enhancement ratio of the target display area based on the current threshold, the current, and the brightness-current relationship coefficient; determining the brightness enhancement ratio of the image displayed in the target display area based on the backlight brightness enhancement ratio and the brightness percentage; determining the brightness reduction ratio of the two-dimensional display area based on the brightness enhancement ratio; determining the current reduction ratio of the two-dimensional display area based on the brightness reduction ratio; and determining the second target current based on the current reduction ratio and the current of the LEDs contained in the two-dimensional display area.

[0140] For example, according to the current threshold I max Based on the current I1 and the brightness-current relationship coefficient K, the backlight brightness enhancement ratio of the target display area can be determined as follows: Based on the backlight brightness enhancement ratio and the brightness ratio of the image displayed in the target display area, the brightness enhancement ratio of the image displayed in the target display area can be determined as follows: Based on the brightness increase ratio, the brightness reduction ratio of the two-dimensional display area can be determined as follows: Based on the brightness reduction ratio, the current reduction ratio of the two-dimensional display area can be determined as follows: Based on the current reduction ratio and the current of the LEDs contained in the two-dimensional display area, the second target current can be determined as follows:

[0141] In S805, based on the adjusted power consumption of the display being equal to the power threshold, a third target current is obtained according to the current current of the LEDs contained in the LED area, the brightness ratio of the image displayed in the target display area, the brightness-current relationship coefficient, and the resistance of the LEDs.

[0142] Among them, the third target current is less than the current threshold.

[0143] For example, the third target current is denoted by I3, considering the maximum output power (i.e., power threshold) P of the LED's power supply. max Due to limitations, the value of I3 must satisfy the condition that the adjusted power consumption of the display is exactly P. max , that is (GH-PQ)·I4·V4+PQ·I3·V3=P max Where I4 represents the fourth target current to which the current of the LEDs contained in the two-dimensional display area is to be reduced. For details on how to obtain the fourth target current I4, please refer to subsequent embodiments; V3 and V4 are the voltages of the LEDs when the currents are I3 and I4, respectively. Therefore, the third target current I3 can be obtained using the following formula:

[0144]

[0145] Where R represents the resistance of the LED; I3 < I max .

[0146] In S806, the current of the LEDs contained in the LED area is increased from the current to the third target current; and a fourth target current is determined based on the third target current, the current current, and the brightness-current relationship coefficient; and the current of the LEDs contained in the two-dimensional display area is reduced to the fourth target current.

[0147] In this step, after obtaining the third target current, the current of the LEDs within the LED area can be adjusted from the current to the third target current. After adjusting the current of the LEDs within the LED area to the third target current, the brightness of the naked-eye 3D display area is improved, but it is still lower than the brightness of the 2D display area. To maintain equal brightness in the displayed image, the current of the LEDs in the 2D display area needs to be appropriately reduced. The fourth target current I4 can be determined based on the third target current I3, the current I1, and the brightness-current relationship coefficient K. After determining the fourth target current, the current of the LEDs within the 2D display area is reduced to the fourth target current, achieving consistent brightness between the naked-eye 3D display area and the 2D display area, but both will be lower than their original brightness before adjustment.

[0148] Further, optionally, determining the fourth target current based on the third target current, the current, and the brightness-current relationship coefficient may include: determining the backlight brightness enhancement ratio of the target display area based on the third target current, the current, and the brightness-current relationship coefficient; determining the brightness enhancement ratio of the image displayed in the target display area based on the backlight brightness enhancement ratio and the brightness percentage; determining the brightness reduction ratio of the two-dimensional display area based on the brightness enhancement ratio; determining the current reduction ratio of the two-dimensional display area based on the brightness reduction ratio; and determining the fourth target current based on the current reduction ratio and the current of the LEDs contained in the two-dimensional display area.

[0149] For example, based on the third target current I3, the current I1, and the brightness-current relationship coefficient K, the backlight brightness enhancement ratio of the target display area can be determined as follows: Based on the backlight brightness enhancement ratio and the brightness ratio of the image displayed in the target display area, the brightness enhancement ratio of the image displayed in the target display area can be determined as follows: Based on the brightness increase ratio, the brightness reduction ratio of the two-dimensional display area can be determined as follows: Based on the brightness reduction ratio, the current reduction ratio of the two-dimensional display area can be determined as follows: Based on the current reduction ratio and the current of the LEDs contained in the two-dimensional display area, the fourth target current I4 can be determined as follows:

[0150] It is understandable that steps S802 to S804 correspond to the case where the power consumption of the adjusted display is less than the power threshold, while steps S805 and S806 correspond to the case where the power consumption of the adjusted display is greater than or equal to the power threshold.

[0151] In S807, the first brightness of each pixel in the adjacent display area is determined based on the brightness of the LED after the current is increased; the second brightness of each pixel in the adjacent display area is determined based on the brightness of the two-dimensional display area; the third brightness of each pixel in the adjacent display area is determined when the two-dimensional display is performed; and the target deflection degree is determined based on the current deflection degree of the liquid crystal molecules, the deflection coefficient, the first brightness, the second brightness, and the third brightness.

[0152] The deflection coefficient is determined based on the characteristics of the LED itself.

[0153] In this step, after adjusting the current of the LEDs in the LED area corresponding to the target display area, in order to avoid excessively high display brightness in the adjacent display areas, it is necessary to adjust the deflection degree of the liquid crystal molecules in the display panel of the adjacent display area. Figure 11This is a schematic diagram of the brightness trend curve of the display screen after adjusting the LED current in the LED area according to an embodiment of this application, as shown in the figure. Figure 11 As shown, the brightness trend curve of the display screen is distributed after the current of the LED corresponding to the naked-eye 3D display area is increased. It can be seen that the brightness of the adjacent 2D display area (i.e., the adjacent display area) is relatively high due to the influence of the light from the LED with increased current, resulting in an uneven trend. Therefore, it is necessary to control the degree of deflection of the liquid crystal molecules in this adjacent display area, that is, to reduce the degree of deflection of the liquid crystal molecules in proportion to the increase in brightness. Figure 12 This is a schematic diagram illustrating the control of liquid crystal molecules in a display panel according to an embodiment of this application, as shown below. Figure 12 As shown, the deflection control trend curve of liquid crystal molecules is illustrated.

[0154] Optionally, the target deflection degree is determined based on the current deflection degree of the liquid crystal molecules, the deflection coefficient, the first brightness, the second brightness, and the third brightness. This includes: determining the difference between the sum of the first brightness and the second brightness and the third brightness; determining the brightness increase ratio based on the ratio of the difference to the third brightness; and determining the target deflection degree based on the product of the current deflection degree of the liquid crystal molecules, the deflection coefficient, and the brightness increase ratio. The first brightness, second brightness, and third brightness are obtained based on the natural exponential function corresponding to a single LED light pattern, which is obtained by numerical fitting based on the measurement data of a single LED light pattern.

[0155] The following detailed embodiments illustrate how to determine the target deflection degree of liquid crystal molecules in adjacent display areas of the target display area. Figure 13 A schematic diagram of the light pattern and backlight light pattern of a single LED provided in an embodiment of this application is shown below. Figure 13 As shown, for a single LED, its emitted light, after passing through the diffuser and optical film, exhibits a light pattern that follows a natural exponential function. The superposition of light patterns from multiple LEDs creates a backlight pattern that gradually decreases in intensity from the center outwards. The light pattern of a single LED can be described using the natural exponential function as shown in Formula 3:

[0156]

[0157] Where x and y represent the abscissa and ordinate of any point on the backlight, respectively; f1(x, y) represents the brightness of a single LED at (x, y) on the backlight. This function is composed of n natural exponential functions. Specifically, the light pattern distribution of the LED can be obtained through measurement. Based on the measured data, the expression corresponding to the function can be obtained by numerical fitting; a1 to an, b1 to bn, and c1 to cn represent the coefficients of the corresponding natural exponential functions, respectively; x1 represents the abscissa of a single LED in the coordinate system corresponding to the backlight; y1 represents the ordinate of a single LED in the coordinate system corresponding to the backlight.

[0158] After increasing the current of the LEDs in the LED area corresponding to the target display area, the light pattern of the LEDs with increased current can be described by the natural exponential function as shown in Formula 4:

[0159]

[0160] Where Q represents the ratio coefficient between the optical pattern after current boost and the original optical pattern before current boost.

[0161] Figure 14 This is a schematic diagram of the light pattern and backlight light pattern of an LED after increasing the current according to an embodiment of this application, as shown below. Figure 14 As shown, based on Figure 13 For example, when the current of the LED corresponding to the naked-eye 3D display area is increased, the light pattern formed by that part of the LED will change. The backlight light pattern formed after superimposing with the light pattern of the LED in the 2D display area will also be different. Figure 13 The backlight patterns are different. Figure 15 This is a schematic diagram illustrating the brightness of the display area of ​​the display after increasing the current according to an embodiment of this application, as shown below. Figure 15 As shown, when the current of the LED corresponding to the naked-eye 3D display area is increased, the brightness of the adjacent display areas between the naked-eye 3D display area and the 2D display area will be locally higher due to the influence of the LED after the increase in current. To eliminate the high brightness effect in the adjacent display areas, the display panel needs to be compensated, that is, the degree of deflection of the liquid crystal molecules in the adjacent display areas needs to be controlled to reduce the light transmittance of the adjacent display areas.

[0162] For any point in an adjacent display area, assuming it is affected by the light pattern of S LEDs with increased current in the naked-eye 3D display area, the starting position coordinate of the horizontal axis of this part of the LED in the coordinate system corresponding to the backlight is x. s1 The termination position coordinates are x s2 The starting position of the vertical axis is y. s1 The termination position coordinates are y s2The number of LEDs with increased current can be determined by whether the radius of the LED's light spot exceeds its distance from the naked-eye 3D display area. Simultaneously, this point is affected by the light patterns of the LEDs in the T 2D display areas, and the starting position coordinate of the horizontal axis of this part of the LEDs in the coordinate system corresponding to the backlight is x. t1 The termination position coordinates are x t2 The starting position of the vertical axis is y. t1 The termination position coordinates are y t2 The number of LEDs in the 2D display area can be determined by whether the distance between the LED in the 2D display area and the outer edge of the adjacent display area of ​​the target display area is less than its spot radius.

[0163] Referring to Formula 4 above, the brightness of the LED at this point after the current boost from S is:

[0164]

[0165] Where xi represents the x-coordinate of each LED in the S LEDs after current boost; yi represents the y-coordinate of each LED in the S LEDs after current boost. It can be understood that fs(x, y) is the first brightness of each pixel in the adjacent display area determined based on the brightness of the LEDs after current adjustment.

[0166] Referring to Formula 3 above, the brightness of the LEDs at this point originating from T 2D display areas is:

[0167]

[0168] Where xj represents the horizontal coordinate of each LED in the T 2D display areas; yj represents the vertical coordinate of each LED in the T 2D display areas. It can be understood that ft(x, y) is the second brightness of each pixel in the adjacent display areas, determined based on the brightness of the two-dimensional display areas.

[0169] When the naked-eye 3D display area and the adjacent 2D display area only display 2D images, for any point, assuming it is affected by the light patterns of W LEDs, the starting position coordinate of the horizontal axis of these LEDs in the coordinate system corresponding to the backlight is x. w1 The termination position coordinates are x w2 The starting position of the vertical axis is y. w1 The termination position coordinates are y w2 .

[0170] Referring to Formula 3 above, the brightness of this point from W LEDs is:

[0171]

[0172] Where xk represents the horizontal coordinate of each of the W LEDs; yk represents the vertical coordinate of each of the W LEDs. It can be understood that fw(x, y) is the third brightness corresponding to each pixel when adjacent display areas are displayed in two dimensions.

[0173] Therefore, the brightness increase fz(x, y) of the screen can be determined by the adjacent display areas of the naked-eye 3D display area and the 2D display area:

[0174] fz(x,y)=fs(x,y)+ft(x,y)-fw(x,y)

[0175] Based on the ratio of fz(x, y) to the third brightness, the brightness increase ratio can be determined as follows:

[0176]

[0177] Based on the current degree of deflection of the liquid crystal molecules, the deflection coefficient, and the percentage increase in brightness, the target degree of deflection can be determined as follows:

[0178]

[0179] Where E represents the current degree of deflection of the liquid crystal molecules; Z represents the deflection coefficient.

[0180] In S808, the deflection degree of liquid crystal molecules in the adjacent display areas of the target display area is reduced from the current deflection degree to the target deflection degree in order to adjust the brightness of the screen corresponding to the target display area and the adjacent display areas.

[0181] In this step, after obtaining the target deflection degree of the liquid crystal molecules in the adjacent display areas of the target display area, the deflection degree of the liquid crystal molecules in the adjacent display areas of the target display area can be adjusted from the current deflection degree to the target deflection degree, so as to adjust the image corresponding to the target display area and the adjacent display areas, and the brightness of the adjusted image is consistent. Figure 16 This is a schematic diagram illustrating the controlled processing of liquid crystal molecules according to an embodiment of this application, as shown below. Figure 16 As shown, based on Figure 11 The brightness trend of the LED display after the current is increased is shown below. Figure 12 The deflection control trend of liquid crystal molecules shown can be obtained by adjusting the deflection degree of liquid crystal molecules in adjacent display areas of the target display area from the current deflection degree to the target deflection degree, so that the brightness trend curve of the screen displayed by the adjusted display can be obtained, and the brightness of the entire display screen remains consistent.

[0182] The control method provided in this application, in response to an instruction to perform naked-eye 3D display in a target display area of ​​a display, determines an LED area corresponding to the target display area; determines a first target current of the LEDs in the LED area based on the current current of the LEDs in the LED area, the brightness ratio of the image displayed in the target display area, and the brightness-current relationship coefficient; if the first target current is less than a current threshold and the adjusted power consumption of the display is less than a power threshold, then the current of the LEDs in the LED area is increased from the current current to the first target current; if the first target current is greater than or equal to the current threshold and the adjusted power consumption of the display is less than the power threshold, then the current of the LEDs in the LED area is increased from the current current to the current threshold; and determines a second target current based on the current threshold, the current, and the brightness-current relationship coefficient; reduces the current of the LEDs in the 2D display area to the second target current; and, based on the adjusted power consumption of the display being equal to the power threshold, determines the current of the LEDs in the LED area based on the current current of the LEDs in the LED area. The process involves: obtaining a third target current based on the current, the brightness ratio of the image displayed in the target display area, the brightness-current relationship coefficient, and the resistance of the LEDs; ensuring that the third target current is less than a current threshold; increasing the current of the LEDs within the LED area from the current current to the third target current; determining a fourth target current based on the third target current, the current current, and the brightness-current relationship coefficient; decreasing the current of the LEDs within the two-dimensional display area to the fourth target current; determining the first brightness of each pixel in adjacent display areas based on the brightness of the LEDs after the current increase; determining the second brightness of each pixel in adjacent display areas based on the brightness of the two-dimensional display areas; determining the third brightness corresponding to each pixel when the adjacent display areas are displayed in two dimensions; determining the target deflection degree based on the current deflection degree of the liquid crystal molecules, the deflection coefficient, the first brightness, the second brightness, and the third brightness; and reducing the deflection degree of the liquid crystal molecules in the adjacent display areas of the target display area from the current deflection degree to the target deflection degree to adjust the brightness of the images corresponding to the target display area and the adjacent display areas. Since the embodiments of this application adjust the brightness of the backlight by adjusting the current of the LEDs contained in the naked-eye 3D display area, if the brightness of the naked-eye 3D display area is still lower than that of the 2D display area after the brightness is increased, the current of the LEDs in the 2D display area is reduced. At the same time, considering the influence of the LEDs contained in the naked-eye 3D display area after the current adjustment on the adjacent display areas of the naked-eye 3D display area, the deflection degree of the liquid crystal molecules in the adjacent display areas is adjusted to achieve the same brightness between the naked-eye 3D display area and the 2D display area, that is, the brightness of the entire display screen is consistent. Therefore, the image quality of the display device can be improved and the user experience can be enhanced.

[0191] In some embodiments, when the adjustment module 1702 determines the fourth target current based on the third target current, the current current, and the brightness-current relationship coefficient, it may specifically be used to: determine the backlight brightness enhancement ratio of the target display area based on the third target current, the current current, and the brightness-current relationship coefficient; determine the brightness enhancement ratio of the image displayed in the target display area based on the backlight brightness enhancement ratio and the brightness percentage; determine the brightness reduction ratio of the two-dimensional display area based on the brightness enhancement ratio; determine the current reduction ratio of the two-dimensional display area based on the brightness reduction ratio; and determine the fourth target current based on the current reduction ratio and the current of the LEDs contained in the two-dimensional display area.

The LED driver control system identifies the LED area corresponding to this glasses-free 3D display area and then increases the current of the LEDs in that area, thereby increasing brightness. Simultaneously, the display panel control system controls the deflection degree of liquid crystal molecules in adjacent display areas of the glasses-free 3D display area to appropriately reduce the brightness of adjacent display areas.
