液晶显示面板及其驱动方法 Liquid crystal display panel and a driving method

技术领域 FIELD

本发明涉及一种显示装置,特别是涉及一种液晶显示面板及其驱动方^^。 The present invention relates to a display apparatus, particularly to a liquid crystal display panel and a driving side ^^. 背景技术 Background technique

目前市场对于薄膜晶体管液晶显示器(thin film transistor liquid crystal display, TFT-LCD)的性能要求是朝向高对比(high contrast ratio)、 无灰阶反转(no gray scale inversion)、色偏小(little color shift)、 亮度高(high luminance)、高色彩丰富度、高色饱和度、快速反应与广视角等特性发展。 Currently the market for TFT-LCD (thin film transistor liquid crystal display, TFT-LCD) performance requirements toward the high contrast (high contrast ratio), no gray scale inversion (no gray scale inversion), the color is too small (little color shift), high brightness (high luminance), high color-rich, high color saturation, fast response and wide viewing angle characteristics of the development. 目前能够达成广视角要求的技术,例如扭转向列型液晶(TN)加上广!见角月莫(wide viewing film)、共平面切换式(in-plane switching, IPS) 液晶显示器、边际场切换式(fringe field switching)液晶显示器与多域垂直配向式(multi-domain vertically alignment, MVA)薄膜晶体管液晶显示器等方式。 Now possible to achieve a wide viewing angle technical requirements, such as twisted nematic (TN) wide plus! See May Mo angle (wide viewing film), Formula plane switching (in-plane switching, IPS) liquid crystal displays, fringe field switching formula (fringe field switching) liquid crystal display with a multi-domain vertical alignment of formula (multi-domain vertically alignment, MVA) mode liquid crystal display, a thin film transistor.

对于公知的多域垂直配向式液晶显示面板而言,形成于彩色滤光基板或薄膜晶体管阵列基板上的配向突起物(alignment protrusion)或狭缝(slit) 可以使液晶分子呈多方向排列,而得到数个不同的配向领域(domain),因此多域垂直配向式液晶显示面板能够达到广视角的要求。 For known multi-domain vertical alignment type liquid crystal display in terms of panel formed in with the color filter substrate or a TFT array substrate, the projections (alignment protrusion) or slit (Slit) can cause the liquid crystal molecules multidirectional arrangement, and to give a number of different alignment field (domain), therefore the multi-domain vertical alignment type liquid crystal display panel to achieve a wide viewing angle requirements.

图1A为公知多域垂直配向式液晶显示面板的正规化穿透率(normalized transmiUance)与灰阶(gray level)的关系图。 FIG 1A is a normalized transmissivity of the panel (normalized transmiUance) and gray (gray level) of the diagram known multi-domain vertical alignment type liquid crystal display. 请参考图1A,横坐标为灰阶,纵坐标为正规化穿透率。 Please refer to FIGS. 1A, a gray-scale abscissa, the ordinate is the normalized transmissivity. 由图1A可知,虽然公知多域垂直配向式液晶显示面板能够达到广视角的要求,但随着观察视角的改变,穿透率对灰阶的曲线(transmittance-level curve)具有不同的曲率。 Seen from Figures 1A, although the panel is well-known multi-domain vertical alignment type liquid crystal display can achieve a wide viewing angle requirements, but as an observed change in viewing angle, the transmittance having different curvatures grayscale curve (transmittance-level curve). 也就是说,当观察的视角 That is, when observing perspective

改变时,公知多域垂直配向式液晶显示器所显示出的亮度会产生变化,进而导致色偏(color shift)或色饱和度不足(color washout)等问题。 Changing, well-known multi-domain vertical alignment liquid crystal display exhibited a difference in brightness, leading to the color shift (color shift) or insufficient color saturation (color washout) and so on.

为了解决色偏的问题,己有多种公知技术相继被提出,其中一种方法是在单一像素内形成两个亮度不同的显示区。 To solve the problem of color shift, it has a variety of well-known techniques have been proposed, one method is to form two different regions within a single luminance of the display pixel. 利用输入两显示区的数据电压不同,或是利用不同的电容来耦合两显示区的数据电压,以使得单一像素内的两显示区分别产生不同大小的电场,进而促使两显示区的液晶分子有不同程度的倾倒排列。 Using the input data display region of the two different voltages or data voltages coupled to the two display areas using different capacitance, so that the two regions within a single pixel display generates an electric field are of different sizes, and thus causes the liquid crystal molecules has two display areas pouring arrangement different degrees.

图IB为公知一种多域垂直配向式液晶显示面板的显示状态示意图。 FIG IB is known a multi-domain vertical alignment type liquid crystal display panel in a schematic view a display state. 请参 See

考图1B,液晶显示面板10由多个阵列排列的像素12所组成,其中各像素包括一亮显示区B与一暗显示区D。 Test 1B, the liquid crystal display panel 10 arranged in a plurality of arrays consisting of 12 pixels, wherein each pixel includes a bright display region B and a dark display region D. 如图1B所示,各像素12中的亮显示区B与暗显示区D的配置方式在行方向上呈现周期性的变化,而在列方向上,各像素的亮显示区B与暗显示区D的配置方式则固定不变。 As shown in FIG. 1B, each pixel in the display arrangement 12 light dark display region B and region D exhibits periodic changes in the row direction, and in the column direction, each pixel in the bright and dark display region B the display region D the configuration is fixed.

上述这种亮暗分布模式虽然可以改善色偏现象,但是随着液晶显示面板的尺寸日益增大,像素的尺寸以及排列间距越接近人眼可辨识的尺寸范围,因此液晶显示面板容易产生明显的颗粒状亮度分布,进而影响液晶显示面板的显示 Although the above-described distribution pattern of this light-dark color shift can be improved, but as the liquid crystal display panel, increasing the size, the pixel size and the arrangement pitch of the closer to the human eye can recognize the size range, the liquid crystal display panel and therefore prone to significant particulate luminance distribution, thereby affecting the display of the liquid crystal display panel
