Description
本發明係關於一種電泳顯示器,尤指一種在關機後仍可正確顯示畫面之電泳顯示器。The invention relates to an electrophoretic display, in particular to an electrophoretic display which can correctly display a picture after being turned off.
平面顯示裝置(Flat Panel Display)具有外型輕薄、省電以及無輻射等優點,所以被廣泛地應用於電腦螢幕、行動電話、個人數位助理(PDA)、平板電腦等電子產品上。而近年來電泳顯示裝置(electrophoretic display)已被提出,電泳顯示器又稱電子紙(electronic paper),以進一步提供更輕薄、便於攜帶之顯示器。一般而言,電泳顯示裝置包含閘極驅動電路、資料驅動電路、共電壓產生器以及複數畫素。閘極驅動電路係用來提供複數閘極訊號,資料驅動電路係用來提供複數資料訊號,且共電壓產生器係用來提供共電壓電位。電泳顯示器係為一種雙穩態(bistability)顯示器,在沒有供電的情況下仍可維持原先顯示的畫面,因此電泳顯示器可在畫面不需要被更新的時候關閉電源,以達到省電效果。然而,就現有的電泳顯示器而言,當使用者關閉電源時,閘極驅動電路、資料驅動電路、共電壓產生器將分別被關閉,使畫素接收到不同準位的閘極訊號、資料訊號及共電壓電位,因而對畫素產生耦合效用並將畫素的電位拉高或拉低,因此畫素的電位與共電壓電位之間具有電壓差。就用以顯示黑白影像的電泳顯示器而言,若畫素的電位與共電壓電位之間存 在電壓差,且畫素的電位係小於共電壓電位,會吸引電泳顯示器中的黑色粒子往下沉積,使得電泳顯示器在關機後所維持的畫面有黑色有變淡(fading)的現象,亦即畫面將會偏白。Flat Panel Display is widely used in computer screens, mobile phones, personal digital assistants (PDAs), tablet computers and other electronic products because of its slimness, power saving and no radiation. In recent years, electrophoretic displays have been proposed, and electrophoretic displays, also known as electronic papers, further provide a lighter, more portable display. In general, an electrophoretic display device includes a gate drive circuit, a data drive circuit, a common voltage generator, and a plurality of pixels. The gate drive circuit is used to provide a plurality of gate signals, the data drive circuit is used to provide a plurality of data signals, and the common voltage generator is used to provide a common voltage potential. The electrophoretic display is a bistability display that maintains the original display without power supply. Therefore, the electrophoretic display can turn off the power when the screen does not need to be updated to achieve power saving. However, in the case of the existing electrophoretic display, when the user turns off the power, the gate driving circuit, the data driving circuit, and the common voltage generator are respectively turned off, so that the pixels receive the gate signals and data signals of different levels. And the common voltage potential, thus generating a coupling effect on the pixel and pulling the potential of the pixel high or low, so there is a voltage difference between the potential of the pixel and the common voltage potential. In the case of an electrophoretic display for displaying black and white images, if the potential of the pixel is between the potential and the common voltage potential In the case of a voltage difference, and the potential of the pixel is less than the common voltage potential, the black particles in the electrophoretic display are attracted to be deposited downward, so that the image maintained by the electrophoretic display after being turned off has a black fading phenomenon, that is, The picture will be white.
請參考第1圖,第1圖係為習知技術電泳顯示器的時序圖,由上而下依序為閘極訊號、資料訊號、共電壓訊號及畫素電位的時序。在第1圖的舉例中,電泳顯示器在時間點T1之前係為開機狀態,此時閘極訊號的波形係介於正負20伏特(V)之間,且共電壓訊號係呈現負準位。畫素電位的準位會因閘極訊號、資料訊號、共電壓訊號的準位的不同而改變。使用者在時間點T1時將電泳顯示器關閉時(例如按下電泳顯示器的電源開關),共電壓產生器首先於時間點T2進入關閉狀態,因此共電壓訊號從負準位拉至0V的地端電位,畫素電位的準位因而被拉高;接著資料驅動電路於時間點T3進入關閉狀態,而不再傳送資料訊號;最後閘極驅動電路於時間點T4進入關閉狀態,閘極訊號由負20V拉至0V,此時畫素的電位會逐漸小於共電壓訊號的電位,而使共電壓訊號的電位及畫素電位之間逐漸產生電壓差,造成電泳顯示器中的黑色粒子往下沉積,使得電泳顯示器在關機後所維持的畫面有偏白的情形。Please refer to FIG. 1 . FIG. 1 is a timing diagram of a conventional electrophoretic display. The top-down sequence is the timing of the gate signal, the data signal, the common voltage signal, and the pixel potential. In the example of FIG. 1, the electrophoretic display is turned on before time T1, and the waveform of the gate signal is between plus and minus 20 volts (V), and the common voltage signal exhibits a negative level. The level of the pixel potential will vary depending on the level of the gate signal, the data signal, and the common voltage signal. When the user turns off the electrophoretic display at time T1 (for example, pressing the power switch of the electrophoretic display), the common voltage generator first enters the off state at time T2, so the common voltage signal is pulled from the negative level to the ground of 0V. The potential, the potential level of the pixel potential is thus pulled high; then the data driving circuit enters the off state at the time point T3, and no longer transmits the data signal; finally, the gate driving circuit enters the off state at the time point T4, and the gate signal is negative. When 20V is pulled to 0V, the potential of the pixel will gradually be lower than the potential of the common voltage signal, and the voltage difference between the potential of the common voltage signal and the pixel potential will gradually be generated, causing the black particles in the electrophoretic display to deposit downward, so that The screen maintained by the electrophoretic display after shutdown is white.

第二實施例與第一實施例的差別在於,在第二實施例中,採用了不同的閘極訊號以及共電壓訊號,來對畫素電位在時段T2至T7產生補償波形。同樣地,資料驅動器250、閘極驅動器240及共電壓驅動器260係被依序關閉,而關閉資料驅動器250、閘極驅動器240、共電壓驅動器260的方式可如第6圖所示,透過於時間點T5將3.3V的資料電源晶片控制電壓CON1拉到0V、於時間點T6將3.3 V的閘極電源晶片控制電壓CON2拉到0V,以及於時間點T7將3.3 V的共電壓電源晶片控制電壓CON3拉到0V,以依序關閉資料驅動器250、閘極驅動器240、共電壓驅動器260。由第二實施例可知,經由步驟502至520,畫素電位的波形得到補償,因此畫素電位與共電壓訊號的電位之間不具有電壓差,故不會吸引黑色粒子或白色粒子沉積,因此電泳顯示器200在關機之後,關機前的畫面仍可被正常顯示,而不會有顏色變黑或變淡的情形發生。The difference between the second embodiment and the first embodiment is that in the second embodiment, different gate signals and common voltage signals are used to generate a compensation waveform for the pixel potentials in the periods T2 to T7. Similarly, the data driver 250, the gate driver 240, and the common voltage driver 260 are sequentially turned off, and the manner of turning off the data driver 250, the gate driver 240, and the common voltage driver 260 can be as shown in FIG.

It can be seen from the second embodiment that the waveform of the pixel potential is compensated through steps 502 to 520, so that there is no voltage difference between the potential of the pixel and the potential of the common voltage signal, so that black particles or white particles are not attracted, so After the electrophoretic display 200 is turned off, the screen before the shutdown can still be normally displayed without the situation that the color becomes dark or faded.
綜上所述,本發明提供操作電泳顯示器之方法,透過補償畫素電位的波形以及依序關閉資料驅動器250、閘極驅動器240及共電壓產生器260,使得畫素電位與共電壓訊號的電位之間不具有電壓差,因此電泳顯示器200在關機之後,關機前的畫面仍可被正常顯 示,而不會有顏色變黑或變淡的情形發生。In summary, the present invention provides a method for operating an electrophoretic display, which compensates for the waveform of the pixel potential and sequentially turns off the data driver 250, the gate driver 240, and the common voltage generator 260 to make the potential of the pixel potential and the common voltage signal There is no voltage difference between them, so after the electrophoretic display 200 is turned off, the screen before the shutdown can still be displayed normally.
