顯示裝置之調整方法及調整裝置Display device adjustment method and adjustment device

本發明是有關於一種調整方法及調整裝置,且特別是有關於一種顯示裝置之調整方法及調整裝置。The present invention relates to an adjustment method and an adjustment device, and more particularly to an adjustment method and an adjustment device for a display device.

在電腦的輸出入週邊設備中,顯示裝置是不可或缺的一項裝置。如何在讓使用者的眼睛感到舒適的情形下呈現畫面,是判斷一個顯示裝置優劣的重要標準。The display device is an indispensable device in the peripheral device of the computer. How to present a picture in a situation where the user's eyes feel comfortable is an important criterion for judging the merits of a display device.

在省電的考量下,顯示裝置於省電模式中,將以較正常模式低的畫面頻率來呈現畫面。因為畫面頻率低,電源將消耗較少之功率,但是卻也造成了新的問題。畫面頻率的降低將帶來兩個問題:閘極的脈波寬度變寬所造成的充電率及漏電量增加。充電率增加將使畫面變暗,而漏電量增加將使畫面變亮。因為這些改變,顯示裝置的亮度將隨著畫面頻率的不同而改變,造成人眼的不適。此外,頻率降低時,將因正負電壓及共同電壓之差產生不同而造成畫面之閃爍程度不同,亦會造成人眼的不適。Under the consideration of power saving, the display device in the power saving mode will present the picture at a lower picture frequency than the normal mode. Because the picture frequency is low, the power supply will consume less power, but it also creates new problems. The reduction of the picture frequency brings two problems: the charging rate and the leakage current caused by the widening of the pulse width of the gate. An increase in the charge rate will darken the picture, and an increase in the amount of leakage will brighten the picture. Because of these changes, the brightness of the display device will vary with the frequency of the picture, causing discomfort to the human eye. In addition, when the frequency is lowered, the difference in the difference between the positive and negative voltages and the common voltage causes the degree of flicker of the screen to be different, which may cause discomfort to the human eye.

因此,如何設計一個在不同顯示模式切換時,能不影響亮度及閃爍程度之顯示裝置,乃為此一業界亟待解決的問題。Therefore, how to design a display device that can affect the brightness and the degree of flicker when switching between different display modes is an urgent problem to be solved in the industry.

因此本發明的目的就是在提供一種顯示裝置之調整方法,包含下列步驟:提供第一脈波寬度;提供第二脈波寬度;判斷顯示裝置之一畫面頻率;當畫面頻率位於第一畫面頻率範圍,則輸出具有第一脈波寬度之一調整波形;以及當畫面頻率位於第二畫面頻率範圍,則輸出具有第二脈波寬度之一調整波形。Therefore, an object of the present invention is to provide a method for adjusting a display device, comprising the steps of: providing a first pulse width; providing a second pulse width; determining a picture frequency of the display device; and when the picture frequency is in the first picture frequency range And outputting an adjustment waveform having a first pulse width; and outputting an adjustment waveform having a second pulse width when the picture frequency is in the second picture frequency range.

本發明的另一目的是在提供一種顯示裝置之調整裝置,包含:一時間控制模組,連接於顯示裝置之一閘極驅動器;以及一儲存模組,電性連結於時間控制模組。儲存模組係用以儲存第一脈波寬度及第二脈波寬度;其中時間控制模組判斷顯示裝置之一畫面頻率,使當畫面頻率位於第一畫面頻率範圍時,輸出具有第一脈波寬度之一調整波形;當畫面頻率位於第二畫面頻率範圍時,輸出具有第二脈波寬度之一調整波形。Another object of the present invention is to provide an adjustment device for a display device, comprising: a time control module connected to a gate driver of the display device; and a storage module electrically coupled to the time control module. The storage module is configured to store the first pulse width and the second pulse width; wherein the time control module determines a picture frequency of the display device, so that when the picture frequency is in the first picture frequency range, the output has the first pulse wave One of the widths adjusts the waveform; when the picture frequency is in the second picture frequency range, the output has one of the second pulse width adjustment waveforms.

本發明之優點在於藉由本發明之儲存模組所儲存之理想脈波寬度,將脈波寬度調整至一最佳值,俾使亮度能在畫面頻率改變後亦能維持在最佳亮度,而輕易地達到上述目的。The invention has the advantages that the pulse width is adjusted to an optimal value by the ideal pulse width stored by the storage module of the invention, so that the brightness can be maintained at an optimal brightness after the screen frequency is changed, and To achieve the above objectives.

在參閱圖式及隨後描述之實施方式後,具有本發明所屬技術領域之通常知識者便可瞭解本發明之目的、特徵及優點,以及本發明之技術手段及實施態樣。The objects, features, and advantages of the invention will be apparent to those skilled in the <RTI

第1圖係繪示本發明顯示裝置之第一實施例。如第1圖所示,顯示裝置1包含調整裝置10以及閘極驅動器12。調整裝置10包含時間控制模組100以及儲存模組102,其中時間控制模組100連接於顯示裝置1之閘極驅動器12,儲存模組102則電性連結於時間控制模組100。儲存模組102係用以儲存第一脈波寬度及第二脈波寬度。於其他實施例中,儲存模組102可以選擇儲存第三、第四、...、第n脈波寬度,並取決於顯示裝置1具有之顯示模式數目而定,本發明並不限於本實施例所例舉之數目。各脈波寬度係可對應至一畫面頻率範圍。時間控制模組100判斷顯示裝置1之畫面頻率101,使當畫面頻率101位於第一畫面頻率範圍時,輸出具有第一脈波寬度之一調整波形103;當畫面頻率位於第二畫面頻率範圍時,輸出具有第二脈波寬度之一調整波形103。舉例來說,如顯示裝置1具有60Hz及40Hz兩種顯示模式,則當畫面頻率落於55Hz-65Hz區間時,時間控制模組100將擷取儲存模組102中對應55Hz-65Hz之第一脈波寬度之值,而將輸出之調整波形101脈波寬度設定為第一脈波寬度;當畫面頻率101落於35Hz-45Hz區間時,時間控制模組100將擷取儲存模組102中對應35Hz-45Hz之第二脈波寬度之值,而將輸出之調整波形101脈波寬度設定為第二脈波寬度。Fig. 1 is a view showing a first embodiment of the display device of the present invention. As shown in FIG. 1, the display device 1 includes an adjustment device 10 and a gate driver 12. The adjustment device 10 includes a time control module 100 and a storage module 102. The time control module 100 is connected to the gate driver 12 of the display device 1 , and the storage module 102 is electrically connected to the time control module 100 . The storage module 102 is configured to store the first pulse width and the second pulse width. In other embodiments, the storage module 102 can selectively store the third, fourth, ..., nth pulse widths, and depends on the number of display modes that the display device 1 has, and the present invention is not limited to the present embodiment. The number exemplified in the example. Each pulse width can correspond to a picture frequency range. The time control module 100 determines the picture frequency 101 of the display device 1 to output one of the first pulse width adjustment waveforms 103 when the picture frequency 101 is in the first picture frequency range; and when the picture frequency is in the second picture frequency range And outputting one of the second pulse width adjustment waveforms 103. For example, if the display device 1 has two display modes of 60 Hz and 40 Hz, the time control module 100 will capture the first pulse corresponding to 55 Hz-65 Hz in the storage module 102 when the picture frequency falls within the interval of 55 Hz-65 Hz. The value of the wave width is set to the pulse width of the output adjustment waveform 101 as the first pulse width; when the picture frequency 101 falls within the interval of 35 Hz-45 Hz, the time control module 100 will capture the corresponding 35 Hz in the storage module 102. The value of the second pulse width of -45 Hz is set to the pulse width of the output adjustment waveform 101 to the second pulse width.

第二脈波寬度係設定於該第一脈波寬度與第二基準脈波寬度之間,其中第二基準脈波寬度係以第一脈波寬度,藉由第一畫面基準頻率及第二畫面基準頻率間之一倍數關係而取得。以前述之例子來說,第一及第二畫面基準頻率係分別為40Hz及60Hz,第二基準脈波寬度係為第一脈波寬度之60/40,即3/2倍。因此,第二脈波寬度將設定於第一脈波寬度及3/2倍的第一脈波寬度(即第二基準脈波寬度)間。The second pulse width is set between the first pulse width and the second reference pulse width, wherein the second reference pulse width is the first pulse width, by the first picture reference frequency and the second picture Obtained as a multiple of the reference frequency. In the foregoing example, the first and second picture reference frequencies are 40 Hz and 60 Hz, respectively, and the second reference pulse width is 60/40 of the first pulse width, that is, 3/2 times. Therefore, the second pulse width is set between the first pulse width and the third pulse width (ie, the second reference pulse width) of 3/2 times.

第2圖為本發明之調整波形之波形圖。如第2圖所示,訊號組20表示兩種畫面頻率,訊號組21代表具有第一脈波寬度210及第二基準脈波寬度211之調整波形,訊號組22代表具有第一脈波寬度210及第二脈波寬度212之調整波形。Figure 2 is a waveform diagram of the adjustment waveform of the present invention. As shown in FIG. 2, the signal group 20 represents two picture frequencies, the signal group 21 represents an adjustment waveform having a first pulse width 210 and a second reference pulse width 211, and the signal group 22 represents a first pulse width 210. And an adjustment waveform of the second pulse width 212.

於其他實施例中,第二脈波寬度可根據顯示裝置1之第一亮度及第二亮度而設定。第一亮度係為畫面頻率於第一畫面頻率範圍時之亮度;第二亮度係為畫面頻率於第二畫面頻率範圍時之亮度。第二脈波寬度係可使第一亮度與第二亮度差異小於一理想亮度差異值。In other embodiments, the second pulse width can be set according to the first brightness and the second brightness of the display device 1. The first brightness is the brightness of the picture frequency in the first picture frequency range; the second brightness is the brightness of the picture frequency in the second picture frequency range. The second pulse width is such that the first brightness and the second brightness difference are less than an ideal brightness difference value.

調整波形103輸出至顯示裝置1之閘極驅動器12,閘極驅動器12更連接至複數個畫素單元之閘極(未繪示),調整波形103係用以控制畫素單元之充電週期,進而調整顯示裝置1之亮度。The adjustment waveform 103 is output to the gate driver 12 of the display device 1. The gate driver 12 is further connected to the gates (not shown) of the plurality of pixel units, and the adjustment waveform 103 is used to control the charging period of the pixel unit. The brightness of the display device 1 is adjusted.

表一係為針對60Hz轉換至40Hz的顯示模式後,於輸入不同資料灰階等級狀況(L16、L32、L48)下,在調整波形101上分別使用第一脈波寬度、第二基準脈波寬度及第二脈波寬度之亮度值之比較。自表一可以觀察到,如未更改脈波寬度而繼續使用第一脈波寬度(即17.4um),亮度將因此變亮;如直接隨頻率等比例改變而使用第二基準脈波寬度(即26um),則亮度將因此變暗;而本發明再進一步調整為第二脈波寬度(即22um)’則可讓亮度維持不變,使人眼感覺舒適。Table 1 is for the display mode of 60Hz conversion to 40Hz, after inputting different data grayscale level conditions (L16, L32, L48), the first pulse width and the second reference pulse width are respectively used on the adjustment waveform 101. And comparison of the brightness values of the second pulse width. It can be observed from Table 1 that if the pulse width is not changed and the first pulse width (ie, 17.4 um) is used, the brightness will be brightened; if the frequency is directly proportional to the frequency, the second reference pulse width is used (ie 26um), the brightness will be darkened accordingly; and the invention is further adjusted to the second pulse width (ie 22um)' to keep the brightness constant and to make the human eye feel comfortable.

於本發明之第二實施例中,儲存模組102可以儲存第一起始時間及第二起始時間。時間控制模組100於畫面頻率101位於第一畫面頻率範圍時,於第一起始時間輸出調整波形103;若畫面頻率位於第二畫面頻率範圍,則於第二起始時間輸出調整波形103。如第2圖所示,訊號組23是代表訊號組22在經過第一起始時間231及第二起始時間232調整後之調整波形103。藉由控制起始時間,可以再進一步令調整波形將顯示裝置之亮度做最佳化之調整。In the second embodiment of the present invention, the storage module 102 can store the first start time and the second start time. The time control module 100 outputs the adjustment waveform 103 at the first start time when the picture frequency 101 is in the first picture frequency range; and outputs the adjustment waveform 103 at the second start time if the picture frequency is in the second picture frequency range. As shown in FIG. 2, the signal group 23 is an adjustment waveform 103 representing the signal group 22 after being adjusted by the first start time 231 and the second start time 232. By controlling the start time, the adjustment waveform can be further adjusted to optimize the brightness of the display device.

第3圖係繪示本發明之第三實施例之顯示裝置。如第3圖所示,顯示裝置3之設置係與第一實施例之不同處僅在於時間控制模組300更包含一偵測模組304及一比較模組306,係其可使調整波形303具有一削角。其中顯示裝置3之閘極驅動器32所連接之畫素單元上(未繪示),更包含一共同電極(未繪示)。偵測模組304係用以偵測調整波形301之一脈波起始及結束時,共同電極之一電壓差。比較模組306係用以比較當畫面頻率301位於該第一畫面頻率範圍時之第一電壓差,及畫面頻率301位於該第二畫面頻率範圍時之第二電壓差,俾使時間控制模組於畫面頻率301從第一畫面頻率範圍轉移至第二畫面頻率範圍時,在第二電壓差大於該第一電壓差的情況下,增加第二脈波之一削角幅度。藉由此削角幅度改變,可調整因頻率降低,、正負電壓及共同電壓之差產生不同而造成畫面之閃爍程度不同而造成之影響,使人眼感到舒適。參照第2圖,訊號組24a、24b、24c係代表訊號組22經過偵測模組304及比較模組306之調整後所產生具有削角之調整波形303,分別輸出至三個畫素單元之閘極後之波形圖。於其他實施例中,更可結合第一實施例而產生如第2圖之訊號組25a、25b、25c,具有適當之脈波寬度、削角及起始時間之調整波形303。Fig. 3 is a view showing a display device of a third embodiment of the present invention. As shown in FIG. 3, the display device 3 is different from the first embodiment only in that the time control module 300 further includes a detection module 304 and a comparison module 306, which can adjust the waveform 303. Has a chamfered corner. The pixel unit (not shown) to which the gate driver 32 of the display device 3 is connected further includes a common electrode (not shown).

The comparison module 306 is configured to compare the first voltage difference when the picture frequency 301 is in the first picture frequency range, and the second voltage difference when the picture frequency 301 is in the second picture frequency range, and enable the time control module. When the picture frequency 301 is shifted from the first picture frequency range to the second picture frequency range, if the second voltage difference is greater than the first voltage difference, one of the second pulse wave clipping amplitudes is increased. By changing the amplitude of the chamfer, it is possible to adjust the effect caused by the difference in frequency, the difference between the positive and negative voltages and the common voltage, and the degree of flickering of the screen is different, so that the human eye feels comfortable. Referring to FIG. 2, the signal groups 24a, 24b, and 24c are representative of the adjustment waveforms 303 of the signal group 22 which are adjusted by the detection module 304 and the comparison module 306, and are output to the three pixel units. Waveform after the gate. In other embodiments, the signal groups 25a, 25b, and 25c of FIG. 2 can be generated in combination with the first embodiment to have an appropriate waveform width 303 of the pulse width, the chamfer, and the start time.

於第四及第五實施例中,當畫面頻率具有改變時,更包含一步驟:偵測調整波形之一脈波起始及結束時,共同電極之一電壓差。若畫面頻率自第一畫面頻率轉換至第二畫面頻率,且第二畫面頻率範圍之第二電壓差大於第一畫面頻率範圍之第一電壓差,即增加該第二脈波之削角幅度。In the fourth and fifth embodiments, when the picture frequency has changed, the method further includes a step of detecting a voltage difference of one of the common electrodes at the start and end of the pulse wave of the adjustment waveform. If the picture frequency is converted from the first picture frequency to the second picture frequency, and the second voltage difference of the second picture frequency range is greater than the first voltage difference of the first picture frequency range, the clipping amplitude of the second pulse wave is increased.
