Technical Field

[0001] The present invention relates to the field of screen display, and in particular to an image display method and an image display system. Background Art

[0002] During the promotion of new markets, customers may require that smaller-resolution images be displayed on a large-resolution module through the platform due to cost considerations or special usage scenario requirements due to limitations on the mobile phone platform.

[0003] New market applications are somewhat different from ordinary consumer mobile phones, and the requirements for resolution and screen-to-body ratio are generally not as high as those for mobile phones. Directly replacing LCD modules with AMOLED modules will not make much difference in the front-end motherboard, and the modules have organic components attached to the periphery. Therefore, the mass-produced modules can be directly used after adaptation and debugging, thus saving the cost and risk of new product development and significantly reducing module costs. However, under normal circumstances, since the modules and platforms are fixed, it is impossible to display images with different resolutions on fixed modules and platforms.

[0004] Therefore, it is necessary to improve the usage of the relevant fixed modules and platforms to solve the above technical problems. Summary of the invention

[0009] The current corresponding to the reserved blank line of the control screen gradually tends to a minimum value, so as to control the display image of the screen to be displayed at a specified position.

[0010] As a further improvement of the present invention, the current corresponding to the reserved blank lines of the control screen gradually tends to the minimum value, specifically:

[0011] The voltage corresponding to the reserved blank line of the screen is controlled to gradually approach the maximum value of the data voltage to control the corresponding current to approach zero.

[0012] As a further improvement of the present invention, the reserved blank lines are divided into front reserved blank lines and rear reserved blank lines, wherein the number of the front reserved blank lines and the number of the rear reserved blank lines are the same.

[0013] As a further improvement of the present invention, the current corresponding to the reserved blank line of the screen is controlled to gradually approach a minimum value, so as to control the display image of the screen to be displayed at a specified position, including:

[0014] The currents corresponding to the front reserved blank lines and the rear reserved blank lines of the control screen gradually tend to the minimum value, so that the display image of the screen is displayed in the middle position of the screen.

[0015] As a further improvement of the present invention, controlling the display image of the screen to be displayed at a specified position includes:

[0016] The voltage corresponding to the current display line number of the control screen is the set data voltage value, and the current display line number of the control screen is normally displayed by the control current corresponding to the data voltage value.

[0017] As a further improvement of the present invention, it also includes:

[0018] Perforations or rounded corners are set on the edges of the screen based on an edge optimization algorithm.

[0019] The present invention also provides a module matching system for screen display, comprising:

[0020] A first determining unit, used to determine the current number of display lines and the original number of display lines of the screen;

[0022] The control unit is used to control the current corresponding to the reserved blank lines of the screen to gradually approach a minimum value, so as to control the display image of the screen to be displayed at a specified position.

[0023] As a further improvement of the present invention, the control unit is used to control the voltage corresponding to the reserved blank line of the screen to gradually approach the maximum value of the data voltage to control the corresponding current to approach zero.

[0024] As a further improvement of the present invention, the reserved blank lines are divided into front reserved blank lines and rear reserved blank lines, wherein the number of the front reserved blank lines and the number of the rear reserved blank lines are the same.

[0025] The control unit is used to control the current corresponding to the front reserved blank line and the rear reserved blank line of the screen to gradually tend to the minimum value, so that the display image of the screen is displayed in the middle position of the screen.

[0026] As a further improvement of the present invention, the control unit is also used to control the voltage corresponding to the current display line number of the screen to be a set data voltage value, so that the current display line number of the screen is controlled to be displayed normally through the control current corresponding to the data voltage value.

[0039] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0040] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] Figure 1 It is a schematic flow chart of an image display method (hereinafter referred to as "method" or "display method") of an embodiment of the present invention, which is used in an image display system to solve the problem that fixed modules and platforms in related technologies cannot display images of different resolutions.

[0043] It should be noted that the method of this embodiment only adjusts the number of rows displayed on the screen, not the columns displayed on the screen, that is, the method of this embodiment defaults to full-screen display in the horizontal direction of the screen. Of course, the method of this embodiment can also be used to adjust the number of columns displayed in the horizontal direction of the screen, by replacing the "rows" involved in the method with "columns", and the details will not be repeated.

[0044] For example, a 2270*1988 display module is used to realize a centered display of 2270*1280 (i.e., the number of columns displayed in the horizontal direction of the screen remains unchanged, which is 2270 columns, and the vertical direction of the screen is adjusted from the original 1988 rows to 1280 rows). The method of this embodiment includes:

[0045] Step 102. Determine the current display line number V of the screen active and the original display line number V original That is, V active =1280, V original =1988.

[0046] Step 104. Based on the current display line number V active 、Original display line number V original and the initial blank line V P Determine the reserved blank lines of the screen. The reserved blank lines are divided into the front reserved blank line V FP Leave a blank line after V BP , where a blank line V is reserved before FP Leave a blank line after V BP The same number. That is:

[0047] V FP =V BP =V P +(V original -V active ) / 2

[0048] If the initial blank line V P =16, then V FP =V BP =370. That is, if the screen displays at 2270*1280, the 370 lines before and after need not display the picture, and the area between the 370 lines before and after needs to display. Figure 2 As shown in FIG. 1 , the signal TE is always in a high level state, and the corresponding screen image is displayed in a black screen (ie, no display). After adjusting the reserved blank line, as shown in FIG. Figure 3 As shown, the signal TE becomes a high level corresponding to the reserved blank line and a low level corresponding to the current display line. The reserved blank line is divided into the front reserved blank line V FP Leave a blank line after V BP Afterwards, Figure 4 As shown, the SIN signal moves forward to the area corresponding to the reserved blank line (i.e., the SIN signal moves forward (1988-1280) / 2 lines), i.e., the porch area. It should be noted that Figures 2 to 4 In the figure, the horizontal axis represents time and the vertical axis represents the screen voltage signal.

[0049] Step 106. Control the current corresponding to the reserved blank line of the screen to gradually approach the minimum value, so as to control the display image of the screen to be displayed at the designated position.

[0050] According to the result of the reserved blank rows calculated in step 104, if it is necessary to make all the reserved blank rows not displayed, it is necessary to control the current corresponding to the reserved blank rows to gradually approach the minimum value (such as zero), so that the corresponding reserved blank rows display a black screen (i.e., no picture is displayed).

[0051] like Figure 5 As shown, step 106 specifically includes: controlling the voltage corresponding to the reserved blank line of the screen to gradually approach the maximum value of the data voltage to control the corresponding current to approach zero.

[0052] I≈K*(ELVDD–Vdata)2

[0053] ≈K*(ELVDD–VGMP)2

[0054] ≈0

[0055] In the formula, I represents the control current corresponding to the screen display line, ELVDD represents the power supply voltage of the screen display, VGAM represents the maximum voltage corresponding to the reserved blank line of the screen, and Vdata represents the voltage corresponding to the reserved blank line of the screen. If the current corresponding to the reserved blank line is to be gradually approached to zero, the voltage Vdata corresponding to the reserved blank line of the screen is to be approached to the maximum value of the data voltage ELVDD (i.e., the maximum voltage VGAM). Set the source level of the porch area to VGMP, set the default Source dot screen of the Blank area, the highest Source voltage is VGMP, and the VGMP voltage is close to ELVDD.

[0056] like Figure 6 As shown, step 106 specifically includes:

[0057] Step 106a. Control the currents corresponding to the front reserved blank lines and the rear reserved blank lines of the screen to gradually approach a minimum value, so that the display image of the screen is displayed in the middle position of the screen.

[0058] It should be understood that the reserved blank line is divided into the front reserved blank line V FP Leave a blank line after V BP Afterwards, Figure 4 As shown, the SIN signal moves forward to the area corresponding to the reserved blank line (i.e., the SIN signal moves forward (1988-1280) / 2 lines), i.e., the porch area. In this way, the currents corresponding to the front reserved blank line and the rear reserved blank line gradually tend to the minimum value, so that the front reserved blank line and the rear reserved blank line both present a black screen state, so that the screen area between the front reserved blank line and the rear reserved blank line is displayed normally, that is, the display image of the screen is in the middle position of the screen.

[0059] like Figure 7 As shown, the display screen of the control screen is displayed at the specified position, including:

[0060] Step 106b. Control the voltage corresponding to the current display line number of the screen to be the set data voltage value, so that the current display line number of the screen is normally displayed by controlling the control current corresponding to the data voltage value.

[0061] It is understandable that for the reserved blank lines, the reserved blank lines can be controlled to be black (i.e., not displayed) by controlling the corresponding current. For the screen area between the front reserved blank line and the rear reserved blank line, the current corresponding to each line of the screen is also controlled separately, so that each line of the screen area can be displayed normally with different pixels.

[0062] In summary, the image display method of this embodiment first determines the current number of display rows and the original number of display rows of the screen, and determines the reserved blank rows of the screen according to the current number of display rows, the original number of display rows and the initial blank rows, so as to adjust the display picture of the screen by controlling the current corresponding to the reserved blank rows to gradually approach the minimum value, so that the display picture is displayed at the specified position. In this way, the method of this embodiment determines the reserved blank rows of the screen by the number of display rows that do not pass the resolution, and finally adjusts the screen display picture by controlling the current corresponding to the reserved blank rows, thereby achieving the purpose of displaying images of different resolutions, overcoming the defects of being unable to output according to the specified resolution due to the limitation of the SOC platform or the need for the SOC to adapt to the AMOLED for re-debugging, that is, solving the problem that the fixed module and platform in the related technology cannot realize the display of images of different resolutions.

[0063] like Figure 8 As shown, the method of this embodiment also includes:

[0064] Step 108. Set a hole or rounded edge on the edge of the screen based on the edge optimization algorithm. Specifically, the water drop or hole setting of the display screen can be realized by the RCN algorithm. The rounded corner modification of the edge of the display screen can be realized by the Notch algorithm. In this way, the 2A2B window setting can be directly used on the DDIC side through this method to overcome the defects of the uncontrollable display effect outside the window area of ​​the screen and the inability to fix the black mask in the related solutions.

[0065] Embodiment 2:

[0066] like Fig. 9 As shown, the present embodiment also provides an image display system 900 (hereinafter referred to as "system"), including: a first determination unit 901, used to determine the current display line number and the original display line number of the screen; a second determination unit 902, used to determine the reserved blank lines of the screen based on the current display line number, the original display line number and the initial blank lines; and a control unit 903, used to control the current corresponding to the reserved blank lines of the screen to gradually approach the minimum value, so as to control the display screen to be displayed at the specified position. Among them, the control unit 903 is specifically divided into a voltage control unit 9031 and a current control unit 9032. Specifically, the voltage corresponding to the reserved blank lines of the screen is controlled by the voltage control unit 9031 to gradually approach the maximum value of the data voltage so as to control the corresponding current to approach zero through the current control unit 9032.

[0067] The image display system 900 of this embodiment first determines the number of current display lines V of the screen by the first determining unit 901. active and the original display line number V original , so that the second determining unit 902 can determine the number of rows currently displayed Vactive 、Original display line number V original and the initial blank line V P The reserved blank lines of the screen are determined, and the control unit 903 controls the current corresponding to the reserved blank lines to gradually approach the minimum value to adjust the display picture of the screen, so that the display picture is displayed at the specified position. In this way, the image display system of this embodiment determines the reserved blank lines of the screen by the number of display lines that do not pass the resolution, and controls the current corresponding to the reserved blank lines, and finally adjusts the screen display picture, thereby achieving the purpose of displaying images of different resolutions, overcoming the defects of being unable to output according to the specified resolution due to the limitation of the SOC platform or the need for the SOC to adapt to the AMOLED for re-debugging, and solving the problem that the fixed module and platform in the related technology cannot realize the display of images of different resolutions.

[0068] In the above embodiment, the reserved blank line is divided into the front reserved blank line V FP Leave a blank line after V BP , where the number of leading and trailing blank lines is the same.

[0069] V FP =V BP =V P +(V original -V active ) / 2

[0070] The control unit 903 is also used to control the current corresponding to the front reserved blank line and the rear reserved blank line of the screen to gradually approach the minimum value, so that the display image of the screen is displayed in the middle position of the screen. It should be understood that the reserved blank line is divided into the front reserved blank line V FP Leave a blank line after V BP Afterwards, Figure 4 As shown, the SIN signal moves forward to the area corresponding to the reserved blank line (i.e., the SIN signal moves forward (1988-1280) / 2 lines), i.e., the porch area. In this way, the currents corresponding to the front reserved blank line and the rear reserved blank line gradually tend to the minimum value, so that the front reserved blank line and the rear reserved blank line both present a black screen state, so that the screen area between the front reserved blank line and the rear reserved blank line is displayed normally, that is, the display image of the screen is in the middle position of the screen.

[0071] Furthermore, the control unit 903 is also used to control the voltage corresponding to the current display number of the screen to be the set data voltage value, so that the current display number of the screen is normally displayed by controlling the control current corresponding to the data voltage value. That is, for the reserved blank lines, the reserved blank lines can be controlled to be black (i.e. not displayed) by controlling the corresponding current. For the screen area between the front reserved blank line and the rear reserved blank line, the current corresponding to each line of the screen is also controlled separately, so that each line area of ​​the screen is normally displayed with different pixels.
