Description

LED显示屏时间片非均匀间隔消隐扫描时间序列调制方法 Non-uniform spacing blanking scan time series modulation method LED display time slices

技术领域 FIELD

[0001] 本发明涉及一种平板显示屏扫描时间序列调制方法,特别涉及一种LED显示屏时间片非均勻间隔消隐扫描时间序列调制方法。 [0001] The present invention relates to a flat screen scanning time sequence modulation method, and particularly relates to the modulation time series blanking scan method of the LED display time slice non-uniform spacing.

[0002] 背景技术 [0002] BACKGROUND OF THE INVENTION

[0003] 平板显示屏LED的显示亮度有两种控制方法。 [0003] There are two methods to control the display luminance of LED flat panel displays. 一种是改变流过LED的电流;另一种方法是利用人眼的视觉惰性,用脉宽调制方法来实现灰度控制,也就是周期性改变光脉冲宽度(即占空比),只要这个重复点亮的周期足够短(即刷新频率足够高),人眼是感觉不到发光象素在抖动。 One is to change the current flowing through the LED; Another method is to use the human visual inertia with a pulse width modulation method to achieve gray scale control, i.e. periodically changing the optical pulse width (i.e. duty cycle), as long as the repeating cycle of light is short enough (i.e., the refresh rate is high enough), the human eye can not feel emitting pixels in the jitter. 由于脉宽调制更适合于数字控制,目前几乎所有的LED屏都是采用脉宽调制来控制灰度等级的。 Since the pulse width modulation is more suitable for digital control, almost all of the LED screen using pulse width modulation are used to control the gray level.

[0004] 目前所采用的标准时间片扫描灰度级控制方法,是将计数器输出的每个周期Tm 看作一个无灰度级的单位周期控制过程(时间片),采用串行传输的方法,在每个周期Tm 内将本行列数据通过比较器形成该周期对应的列数据,传往列驱动器。 [0004] The current standard time slice scanning using gray scale controlling method, each cycle counter is output as a non Tm gradation control process unit cycle (time slice), a serial transmission method, this ranks the data of the data column formed by the comparator corresponding period within each period Tm, transmitted to the column driver. 一般来说,该过程是重叠处理的过程,即在显示本行本周期的各列数据的同时,准备下一个周期的各列数据或下一行的第一周期数据(在显示本行最后一个周期时),此时的周期Tm实际上为一个扫描时间片,在该周期内的显示驱动过程同无灰度的显示屏相同,重复计数器输出的所有周期就会完成显示屏的灰度显示。 In general, the process is a process overlap processing, i.e., each column of data in a display period, while the Bank present, ready for the next cycle of data for each column or the first row of the next data cycle (last cycle in the display Bank ), the period Tm in this case is actually a slice scanning time, the display driving during the same period in the gradation display without the same cycle is repeated for all of the counter output will complete gradation display screen.

[0005] 目前采用的利用权值时间片进行灰度级扫描的控制方法,是利用权值时间 [0005] weights using the time slice currently employed method for controlling a gray level scanning time using weights

片D[i]在单位时间内对显示屏幕进行多次反复扫描(又称刷新),从而形成有灰度级 Sheet D [i] is repeatedly scanned a plurality of times (also known as a refresh) on a display screen per unit time, thereby forming a gray scale level

层次的视频图像;每个LED的导通时间采用了加权求和的方法,对于任意一个LED像 Level video image; on-time of each LED using a weighted sum method, for any LED image

素的灰度值R[MSB : LSB],都有唯一的一个加权时间TK[MSB:uB]和与之相对应,表示为MSB Pigment gradation value R [MSB: LSB], has only a weighted time TK [MSB: uB] and corresponding thereto, it is represented as MSB

TR[MSB:LSB]= ;其中ϋ的值大于等于零时的D[i]占有的时间为一个基准 TR [MSB: LSB] =; wherein D [i] when a value of zero or greater ϋ occupied a reference time

i=LSB i = LSB

时间片,一般LSB = 0。 Time slice, generally LSB = 0. 该方法又称为权值时间片扫描方法,(一般情况下,视频显示单基色数据为8bit,即256灰度级,而目前LED显示可以控制的灰度级一般要大于256灰度,即Sbit ;这里的背景技术假定LED显示可以控制的灰度级的上限为65536,16bit ;实际上还可以更大。i这里表示权时间片的最小时间片,例如显示数据为8bit,LED显示可以控制的灰度级为16bit时,i最小为7,最大为15 ;—共有8个大的时间单位,为D7到D15,如果k = 0的情况下,D7对应的时间片为256,D15对应的时间片为32768,总的时间片和为65535,这是一个特例)为保证单基色灰度级至少为256且单基色灰度级为最高能达到65536,可取7彡C彡15 ;C为MSB与LSB的差值;k为常数,为使图像表现的更加细腻,可取0彡k彡9。 This method is also called time slice weights scanning method (In general, single-color video display data is 8bit, i.e. 256 gray levels, and the current can be controlled by the LED display is generally greater than 256 gray scale gradation, i.e. Sbit ; bACKGROUND herein assumed that the LED display gray levels can be controlled to limit 65536,16bit; .i actually be larger where the right time represents a minimum time slice sheet, for example 8bit data display, the LED display can be controlled gray level is 16bit, i minimum of 7 and a maximum of 15; - a total of eight major unit of time D7 to D15, if the k = 0, D7 corresponding to the time slice 256, D15 corresponding time 32768 sheets, and the total time of 65,535 sheets, which is a special case) to ensure at least one-color gradation 256, and one-color gray levels can reach up to 65,536, preferably 15 7 San San C; and C is the MSB the LSB difference; k is a constant, to make the image appear more delicate, preferably 0 k San San 9. 当i_k的值小于0时,每个权值时间片各自占有一个基准时间片,只是在这个基准时间片里LED显示时间只有一个基准时间片的2i_k倍,有一部分或大部分时间被消隐了。 I_k When the value is less than 0, each weight value each time slice occupies a reference time slice, but only a LED display time 2i_k times the reference time slice of the reference time slot where a part or most of the time there is blanked .

[0006] 这种方法虽然提高了显示屏的刷新频率,但是当i_k的值小于等于0时,在基准时间片里LED显示时间只有一个基准时间片的2i_k倍,有一部分或大部分时间被消隐了,而在连续用完整时间片进行扫描时像素持续点亮,因而在用不同的权值时间片扫描时出现闪动现象,显示的图像动态稳定性较差。 [0006] Although this method improves the refresh rate of the display, but when the value is less than i_k equal 0, LED display time is only a time slice 2i_k times the reference slice at a reference time, there is eliminated a part or most of the time hidden, while the continuous light pixels in successive scanning with the full time slice, thus flicker phenomenon scan different weights with time slice, the dynamic stability of the image display poor. [0007] 另外,中国专利公报还公开了“一种平板显示屏行列时间片分布重组扫描调制方法”(专利号:200510016793. 7 ;公开日:2006. 11. 22),该方法采用的技术方案是:选择k的数值,将扫描面积为LXV的基本驱动点阵的扫描周期分为k个阶段,在每一个阶段内对基本驱动点阵完成一次扫描过程,新的行扫描周期Tl' = V(L • k),在新的行扫描周期完成n,'的调制;其中T,为扫描面积为LXV的基本驱动点阵的巾贞周期,L为基本驱动点阵的扫描行数,V为基本驱动点阵的扫描列数,显示的灰度级为n,,k为大于1小于n,的正整数,n, 能被k整除,= ,¾'为正整数;每完成一个阶段的扫描过程后,进行下一个阶段的扫描,直至完成k个阶段的扫描过程。 [0007] In addition, Chinese Patent Publication also discloses a "recombinant modulation method A flat screen scanning time slot distribution ranks" (patent number: 2005100167937; Publication Date: 2006 11.22), using the technique of the method is: selecting the value k, the scan area LXV lattice basic drive period is divided into k phases scan, a complete scan of the basic drive dot in each stage, the new row scanning period Tl '= V (L • k), a new row in the scan cycle is completed n, 'modulation; wherein T, the scanning area of ​​the basic drive cycle Chen towel lattice LXV, L is the number of scanning lines driven substantially lattice, V is the basic lattice number of drive scan sequence, to display gray levels n ,, k is greater than 1 less than n, a positive integer, n, is divisible by k, =, ¾ 'is a positive integer; each stage of the completion of a scan after the process, the next stage of the scanning, the scanning process is completed until the k stages.

[0008] 时间片分布重组扫描调制方法虽然增加了显示器刷新的速度,但是在某些情况下,仍存在刷新频率不足的情况,显示的图像动态稳定性较差。 Recombinant scanning modulation method [0008] Although the time slot distribution of the display refresh rate increases, but in some cases still insufficient refresh rate, the display of the dynamic stability of the image is poor.
