Description

顯示裝置及其控制方法Display device and control method thereof

本發明是有關於一種顯示裝置及其控制方法，且特別是有關於一種可提升顯示品質的顯示裝置及其控制方法。 The present invention relates to a display device and a control method thereof, and in particular, to a display device and a control method thereof that can improve display quality.

習知技術中，虛擬實境的顯示器，其背光光源都需要等到液晶顯示器的訊號掃描完後才會被點亮，並藉此避免殘影的感覺。但隨著顯示器解析度以及更新頻率的提高，同一幀週期(frame period)中，可能面臨到訊號來不及掃描完或者液晶還未達到穩定狀態就要點亮背光光源。這樣的情況，將導致顯示畫面出現嚴重的殘影現象。 In the conventional technology, the backlight of the virtual reality display needs to wait until the signal of the liquid crystal display is scanned before it is lit, thereby avoiding the feeling of afterimage. However, with the improvement of display resolution and update frequency, in the same frame period, the backlight source may be turned on before the signal has time to be scanned or the liquid crystal has not reached a stable state. Such a situation will lead to serious image retention on the display screen.

本發明提供一種顯示裝置及其控制方法，可有效提升顯示品質。 The present invention provides a display device and a control method thereof, which can effectively improve display quality.

本發明的顯示裝置包括顯示面板、第一光源以及第二光源。第一光源鄰近顯示面板的第一側邊進行設置，對應顯示面板 的第一部份顯示區域。第二光源鄰近顯示面板的第二側邊進行設置，對應顯示面板的第二部份顯示區域，其中第一側邊與第二側邊相對。其中第一光源以及第二光源分別在第一時間區間以及第二時間區間被點亮，第一時間區間以及第二時間區間中具有間隔時間。 The display device of the present invention includes a display panel, a first light source and a second light source. The first light source is arranged adjacent to the first side of the display panel, corresponding to the display panel The first part of the display area. The second light source is disposed adjacent to the second side of the display panel, corresponding to the second partial display area of the display panel, where the first side is opposite to the second side. The first light source and the second light source are respectively lit in the first time interval and the second time interval, and there is an interval time in the first time interval and the second time interval.

本發明的控制方法包括：鄰近顯示面板的第一側邊設置第一光源，使第一光源對應顯示面板的第一部份顯示區域；鄰近顯示面板的第二側邊設置第二光源，使第二光源對應顯示面板的第二部份顯示區域，第一側邊與該第二側邊相對；以及，分別在第一時間區間以及第二時間區間點亮第一光源以及第二光源，其中第一時間區間以及第二時間區間中具有間隔時間。 The control method of the present invention includes: setting a first light source adjacent to the first side of the display panel so that the first light source corresponds to the first part of the display area of the display panel; setting a second light source adjacent to the second side of the display panel so that the second light source The two light sources correspond to the second part of the display area of the display panel, and the first side is opposite to the second side; and the first light source and the second light source are respectively lit in the first time interval and the second time interval, wherein the first light source and the second light source are respectively lit. There is an interval time in the first time interval and the second time interval.

基於上述，本發明的顯示裝置具有側入式的第一光源以及第二光源，並透過在第一部分顯示區的畫素穩定後點亮對應的第一光源，並在第二部分顯示區的畫素穩定後點亮對應的第二光源。如此一來，顯示裝置不會在光源點亮過程中，因畫素的不穩定動作而產生殘影現象，可有效提升顯示品質。 Based on the above, the display device of the present invention has a side-type first light source and a second light source, and lights up the corresponding first light source after the pixels in the first part of the display area are stabilized, and lights up the pixels in the second part of the display area. After the element is stable, the corresponding second light source is turned on. In this way, the display device will not produce residual images due to unstable movements of the pixels during the lighting process of the light source, which can effectively improve the display quality.

In step S630, the first light source and the second light source are respectively lit in the first time interval and the second time interval, where there is an interval time in the first time interval and the second time interval.

關於上述步驟的實施細節，在前述的實施例中已有詳細的說明，在此恕不多贅述。 The implementation details of the above steps have been described in detail in the foregoing embodiments and will not be described again here.

綜上所述，本發明的顯示裝置透過在顯示面板相對的兩個側邊上設置側入式光源，並透過在對應的畫素穩定後，分時點亮側入式光源，可有效減低因畫素(液晶翻轉)的不穩定狀態所造成的殘影現象，有效提升顯示品質。 To sum up, the display device of the present invention can effectively reduce the risk by arranging side-illuminated light sources on two opposite sides of the display panel, and by lighting up the side-illuminated light sources in a time-sharing manner after the corresponding pixels are stabilized. The image retention phenomenon caused by the unstable state of pixels (liquid crystal flipping) effectively improves display quality.
