Description

显示控制的方法及设备 The display control method and apparatus

技术领域 FIELD

[0001] 本发明涉及数字通信领域,具体而言,本发明涉及显示控制的方法及设备。 [0001] The present invention relates to digital communications, in particular, the present invention relates to a display control method and apparatus. 背景技术 Background technique

[0002] 如何控制LED的亮度,技术发展从开始的模拟调光方式到现在的脉宽调制脉冲调光方式,甚至现在很多应用中可以将模拟调光和脉宽调制脉冲调光结合使用。 [0002] How to control the LED brightness, analog dimming technology from the beginning to the present embodiment the pulse width modulation burst dimming mode, even now many applications may be analog dimming and pulse width modulation dimming pulse combination. 模拟调光是指,通过写入的数据,调节流过LED的电流大小,使得LED亮度发生变化。 Analog dimming means, the data written by adjusting magnitude of the current flowing through the LED so that the LED luminance change. 脉宽调制脉冲调光是指,通过在一段时间内,调节LED亮或者灭的时间宽度。 Width modulated pulse dimming means, LED light off time width or a period of time by adjusting. LED导通的时候,是固定电流驱动,可以通过外置电阻设定;LED关断的时候,没有电流通过。 When the LED is turned on, driving current is fixed, it can be set by an external resistor; when the LED is off, no current flows through. 这样,在一定的时间内的显示效果是灯的亮度发生了变化。 Thus, in a certain display time it is the brightness of the lamp changes. 并且在这个固定时间内,灯亮的时间越长,总体效果为灯就越亮。 And within the fixed time, the longer the time the lights, the overall effect of the brighter light. 这样可以达到在一定时间内,对LED进行亮度调节的目的。 Such can be achieved within a certain time, the LED luminance adjusting the purpose.

[0003] 模拟调光的缺点主要有如下两点:1、改变经过LED的电流,会改变LED的光色, 这样会使得像素的色配增加很多不确定性;2、如果要增加LED的灰度等级,需要高精度的DAC,其线性度和精度受到限制。 [0003] The main drawback of analog dimming the following points: 1, changing the current through the LED, the LED light will change color, so that the pixel color will increase with many uncertainties; 2, if you want to increase the LED gray grade, high accuracy is required of the DAC, their limited linearity and accuracy.

[0004] 脉宽调制脉冲调光则完全规避了上述模拟调光的缺点。 [0004] width modulated pulse dimming completely avoid the disadvantages of the analog dimming. 灯点亮的时候,流过的是固定的电流,光的波长不会变化。 Lamp is lit when the flowing current is fixed, the wavelength of light does not change. 如果需要增加灰度等级,将用于脉宽调制脉冲的基本时钟提速,在原来固定的时间周期内,容许的占空比选择会更多;或者将原来时间周期加长,用原有的基本时钟,也会有更多的占空比选择。 If additional gray scale, for the pulse width modulation speed basic clock pulse, in the original fixed time period, will be more tolerable duty cycle selector; the original time period or longer with the original base clock , the duty cycle will have more choice.

[0005] 所以,业内基本都采用脉宽调制脉冲调光的方式对LED调光。 [0005] Therefore, the industry uses basically the burst dimming mode pulse width modulation dimming of the LED. 不过,脉宽调制脉冲调光也有自身的缺陷。 However, the burst dimming pulse width modulation has its own shortcomings. 因为此种调光方法是需要将亮度在一定时间内平均的,所以当LED 的灰度等级较高时,周期较长。 Since this dimming method is the need to average brightness within a certain time, when the high gradation LED, a longer period. 这样,LED亮或灭的时候,或者捕捉的时间太短,以至于该时间内接受到的亮灭比,不能很真实的体现原有亮灭比。 In this way, LED on or off when the time is too short or capture that received within this time than the light off, it can not reflect the true original light off ratio. 摄像机等数码摄像产品拍摄画面时, 捕捉时间远远小于人眼对画面的捕捉时间。 Cameras and other digital imaging products when taking pictures, capturing time is much smaller than the human eye to capture the time on the screen. 这样,人眼看起来较清晰的画面,被摄像机或者相机拍摄时,画面可能造成闪烁感,或者说产生条纹。 In this way, the human eye looks clearer picture taken by the camera or the camera, the picture may cause light flashes, or streaks.

[0006] 现在人们要求显示画面越来越清晰,画面内容越来越复杂。 [0006] It is now increasingly clear requirements of the display screen, the picture is more complex content. 这就是说,画面的数据量越来越大,而同时需要较高的平板显示刷新频率。 That is to say, the amount of data the screen more and more, while flat panel display requires a higher refresh rate. 这就需要平板显示芯片能以更高的频率生成脉宽调制脉冲信号,并且不影响原有数据的精度。 This requires a flat display chip width modulated pulse signals can be generated at a higher frequency and does not affect the accuracy of the original data.

[0007] 现有的方法中,都是采用系统传送芯片处理的方法。 [0007] In the conventional method, the method is transmitting chip processing system. 这种方法是将显示的有效时间平均分布在一个脉宽调制基本周期中。 This method is effective time display is evenly distributed in a fundamental pulse width modulation cycle. 这样可以解决静态屏的上述条纹或者闪烁的问题。 This can solve the above static screen stripes or flickering problem. 但是在动态屏中,刷新率主要取决于换行扫描的频率,简称为行扫频率。 However, in a dynamic screen, the refresh rate depends on the frequency of the scanning line feed, simply referred to as the line scan frequency. 依照上述方法, 如果显示一个固定精度或者数据位数的亮度,需要在每一行LED灯完整显示一个脉冲宽度调制基本周期后,才能换行。 In accordance with the method described above, if the brightness of a fixed number of data bits or the accuracy of the display, the display requires a pulse width modulation period substantially complete in every row LED lamp, in order to wrap. 动态屏的刷新率用如下公式表述: Dynamic screen refresh rate expressed by the following equation:

[0008] [0008]

Figure CN102194421AD00041

[0009] 其中是行扫频率,Fgclk是基本时钟的频率,η是显示数据精度或者显示数据位数,m是扫描行数。 [0009] where is the line scan frequency, Fgclk basic clock frequency, η is the accuracy of the display data or the display data bits, m is the number of scanning lines. [0010] 如果沿用原有的方式进行,数据的精度越高,动态屏的刷新率就越低。 [0010] If you use the original way, the higher the accuracy of the data, the dynamic refresh rate of the lower screen. 但是刷新率较低,则会影响到拍摄效果。 But the refresh rate is low, it will affect the shooting.

[0011] 因此,有必要提出一种有效的技术方案,在显示数据精度较高时,能有效提高显示的刷新频率。 [0011] Accordingly, it is necessary to provide an effective technical solution, when the data shows a high accuracy, can effectively improve the refresh rate of the display.

具体实施方式 detailed description

[0033] 下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。 [0033] Example embodiments of the present invention is described in detail below, exemplary embodiments of the embodiment shown in the accompanying drawings, wherein same or similar reference numerals designate the same or similar elements or elements having the same or similar functions. 下面通过参考附图描述的实施例是示例性的,仅用于解释本发明,而不能解释为对本发明的限制。 By following with reference to the embodiments described are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0034] 现有的方法中,都是采用系统传送芯片处理的方法,示意图如图1所示,主控装置输出信号A、B、C控制译码驱动单元,控制译码驱动单元输出信号控制显示屏;从机装置根据主控装置输入的数据进行显示控制。 [0034] In the conventional method, the method is transmitting chip processing system, As shown in Figure, the master device output signals A, B, C control decoder driving unit 1, the control unit outputs a drive signal to control the decoder display; a display control device of the slave master data input. 这种方法是将显示的有效时间平均分布在一个脉宽调制基本周期中。 This method is effective time display is evenly distributed in a fundamental pulse width modulation cycle. 这样可以解决静态屏的上述条纹或者闪烁的问题。 This can solve the above static screen stripes or flickering problem. 但是在动态屏中,刷新率主要取决于换行扫描的频率,简称为行扫频率。 However, in a dynamic screen, the refresh rate depends on the frequency of the scanning line feed, simply referred to as the line scan frequency. 如图2所示。 as shown in picture 2. 主控装置接收到显示数据后,根据显示数据的灰度等级,来调整译码驱动单元的输入信号。 After the master device receives the display data, in accordance with gradation display data, decoding an input signal to adjust the drive unit. 图2所示图中,C信号是译码驱动单元的最大时间长度输入,其频率代表了一个完整扫描频率。 Shown in FIG. 2, C is the maximum time length of the input signal decoding drive unit, which represents a complete frequency sweep frequency.

[0035] 依照上述方法,如果显示一个固定精度或者数据位数的亮度,需要在每一行LED 灯完整显示一个脉冲宽度调制基本周期后,才能换行。 [0035] According to the above method, if the brightness of a fixed number of bits or data show the precision required after each line the LED display a complete period of the basic pulse width modulation, to wrap. 这样,动态屏的刷新率用如下公式表述: Thus, the dynamic refresh rate of the screen expressed by the following equation:

_6] Fframe=^-; _6] Fframe = ^ -;

[0037] 其中是行扫频率,Fgclk是基本时钟的频率,η是显示数据精度或者显示数据位数,m是扫描行数。 [0037] where is the line scan frequency, Fgclk basic clock frequency, η is the accuracy of the display data or the display data bits, m is the number of scanning lines.

[0038] 假设显示数据精度n = 12,m = 8,那么这是一个8扫的灰度数据精度为12级的显示屏。 [0038] assumed that the display data precision n = 12, m = 8, then this is an eight-gray-precision data for 12 scan the display screen. 图2中所示每一行的数据Dl〜D8的数据长度为12位,而每一行完整的时间为2n =4096个基本时钟GCLK,其中LED灯点亮的有效时间或占空比是由数据决定的。 Each row of data shown in Figure 2 is the data length Dl~D8 12, and complete the time for each line is 2n = 4096 basic clocks the GCLK, wherein the effective time or duty cycle of LED lights is determined by the data of. 显示屏从第1行开始显示,到第8行显示结束,所用的时间为4096*8 = 32768个GCLK。 Screen is displayed from the line 1, to show the end of the line 8, the time taken for the 4096 * 8 = 32768 GCLK. 应用中,采用Fgclk的频率为16. 7MHz, C信号的频率为: Applications, a frequency of Fgclk 16. 7MHz, the frequency of the signal C is:

Γ Ί Γ \6.1MHz …υ Γ Ί Γ \ 6.1MHz ... υ

[0039] Fc= 2l2*8 =510Ηζ。 [0039] Fc = 2l2 * 8 = 510Ηζ.

[0040] 这样,数据的精度越高,动态屏的刷新率就越低。 [0040] Thus, the higher the accuracy of the data, the dynamic refresh rate of the lower screen. 譬如说数据精度是16比特的,即η = 16,采用FeaK的频率为16. 7MHz,8行扫描屏,即m = 8,那么Fftame = 31. 8Hz。 Accuracy, say 16 bits of data, i.e., η = 16, with a frequency of FeaK 16. 7MHz, 8 screen scan line, i.e., m = 8, then Fftame = 31. 8Hz.

[0041] 图2中,Ll〜L8是8扫屏中某连续8行LED灯的显示情况,由某一个芯片(从机装置)的同一个驱动脚驱动。 In [0041] FIG 2, Ll~L8 8 is a case where a scan screen 8 successive lines of LED lights by one chip (the slave device) of a drive pin driving the same. 主控装置发送数据的顺序为Dl —D2 —......D8。 Transmission data sequence to the master device Dl -D2 -...... D8. 从机装置输出的低电平为し£0灯关闭丄£0点亮的顺序依次为第ー行,第ニ行,......,第八行。 Outputted from the low level unit to the lamp off Shang shi £ £ 0 0 order sequentially as the first lighting ー row, the first row ni, ......, the eighth line. 在图 In Fig.

示し1〜し8内,存储的数据决定其点亮的时间。 Shi shi 1 ~ 8 illustrates the data store to determine their lighting time.

[0042] 以11= 12为例,因为需要显示12比特的数据精度,所以在锋个换行时间内,必须发送4096( = 2i2)个600(周期。 [0042] In Example 11 = 12, since the required accuracy of the 12-bit display data, so that a change in the front lines of time, must be sent 4096 (= 2i2) a 600 (cycles.

[0043] 在图示波形中,刷新率可以简单的用如下公式表示: [0043] In the illustrated waveform, the refresh rate can be simply expressed by the following equation:

Figure CN102194421AD00071

[0045] 其中n是数据精度位数,m是动态屏行扫数。 [0045] where n is the accuracy of the data bits, m is the number of scan lines dynamic screen.

[0046] 譬如上例中,需要显示12比特的数据精度,8扫动态屏,6〔0(的频率为31. 25MHz, [0046] For example the embodiment, the display data required precision 12-bit, 8-screen dynamic sweep frequency [0 6 (of 31. 25MHz,

那么使用此方法,极限的显示刷新率为: So use this method, display refresh rate limit is:

Figure CN102194421AD00072

[0048] 应用中,因为换行时需要保留消隐时间(即两组4096个GCLK的间隔),所以显示刷新率实际约为900Hz。 [0048] applications, because the need to retain linefeed blanking interval (i.e. the interval of two GCLK 4096), so that the actual display refresh rate is about 900Hz. 如果想继续提升刷新率,只有通过降低数据精度或减少行扫行数的方式。 If you want to continue to improve the refresh rate, only by reducing the accuracy of the data, or to reduce the number of scan lines in rows. 前者会使得显示效果不佳,人眼能够觉察到该细微差别;后者使得成本增加,8扫描变4扫描,芯片数量提升1倍。 The former makes the display will be poor, the human eye can perceive the nuances; which increase costs, streak 4 8 scan, the number of chips increases by 1 times. 显然,上述两种情况都存在缺陷不可行。 Obviously, these two cases are flawed feasible.

[0049] 刷新率较低,会影响到拍摄效果,如图3所示。 [0049] The lower refresh rate, will affect the shooting, as shown in FIG. 为了实现本发明之目的,本发明实施例提出了ー种显示控制的方法,包括以下步[0050] To achieve the object of the present invention, embodiments of the present invention proposes a method ー kinds of display control, comprising the steps [0050]

骤: Step:

[0051] [0051]

[0052]主控装置接收m个显示精度为N的待显示数据; [0052] The master device receives the m-th display precision of N data to be displayed;

根据数据传输协议,所述主控装置将锋个所述显示精度为N的待显示数据处理为2N_n部分,将所述m个显示精度为N的待显示数据处理为m*2N_n部分,得到对应编号为k(i, j)的数据序列,其中,1 くi くm, 1 くj く2N_n, 1 くn くN,n为实际显示时锋行的数据精度, m为显示屏的行扫描行数; The data transfer protocol, the master device to the front of said N display accuracy of data to be displayed as 2N_n processing section, the accuracy of the m N display data to be displayed is m * 2N_n processing section, to give the corresponding data sequence number K (i, j), where 1 ku i ku m, 1 ku j ku 2N_n, 1 ku n ku N, the data precision of n is the actual display front row, m is the row scanning line of the display number;

[0053] 所述主控装置将所述m*2N_n部分数据以m为周期给从机装置发送数据,其中,第j 个周期按照1到m的顺序依次发送编号为k(i,j)的数据给所述从机装置,所述主控装置通过译码驱动单元控制显示屏,所述从机装置根据接收的所述/-n*m部分数据进行显示控制。 [0053] The master device to said m * 2N_n partial data in m machine cycles to transmit data from the device, wherein the j-th transmission period are sequentially numbered k (i, j) in the order of 1 to m data to the slave device, the master device controls the display screen by decoding the driving unit, the display control apparatus according to the slave receiving / -n * m data portion.

[0054] 如图4所示,为本发明实施例显示控制的方法流程图,包括以下步骤: [0054] As shown in FIG 4, a display control method according to the flowchart embodiment of the present invention comprises the steps of:

[0055] SllO :主控装置接收显示精度为N的待显示数据。 [0055] SllO: means for receiving a master display precision of N data to be displayed.

[0056] 在步骤SllO中,主控装置接收到完整ー巾贞的原始数据,锋行的数据位数为N,即主控装置接收m个显示精度为N的待显示数据。 [0056] In step SllO, the master device receiving the original data integrity ー towel Zhen, the front row of data bits is N, i.e., the master device receives the m-th display precision of N data to be displayed. 如果显示屏是m行扫描的动态屏,譬如是8 行扫描的动态屏,那么m = 8;特殊的,如果是窬态屏,此时m=l。 If the display screen is dynamically m row scanning, such scanning lines are dynamic screen 8, then m = 8; particular, if the state is the hole in a wall panel, when m = l. 对于m行扫描的动态屏, 因为主控装置需要在锋个扫描周期内,共发送m次数据,对应到显示屏的第1行至第m行的LED灯。 For dynamic scanning line m screen, because the master device needs to be within the front scan cycle, a total of m times the data transmission to the row corresponding to the first to m-th row of the LED display. 窬态屏在锋个扫描周期内,仅发送1次数据。 State in the front hole in a wall panel scan cycle, data is transmitted only once.

[0057] 由刷新率和基本时钟(GCLK)时间决定了1行扫描的时间,选取锋1行的完整周期是2"*T_,即1行要显示2"个T_时间长度的占空比,且有n くN, n是显示数据精度或者显示数据位数。 [0057] 1 determined by the line scan time and refresh rate of the basic clock (the GCLK) time, a front row select complete cycle is 2 "* T_, i.e. 2 to show one line" length of the duty cycle time T_ , and n-ku N, n is a number of bits of display data or the accuracy of the data.
