Description

顯示裝置display device

本發明是有關於一種顯示裝置，且特別是有關於一種包含兩個顯示面板的顯示裝置。 The present invention relates to a display device, and more particularly, to a display device including two display panels.

近幾年，為了增加顯示裝置的亮暗對比度，常將光閘面板疊加於彩色顯示面板上。光閘面板是一種能夠控制光線的通過與否的面板。在不希望光線通過的部分(例如顯示畫面的黑色部分)，光閘面板能阻擋光線，而在希望光線通過的部分(例如顯示畫面的彩色部分)，光閘面板能讓光線通過，藉此能增加顯示裝置的亮暗對比度。 In recent years, in order to increase the light-dark contrast ratio of a display device, a shutter panel is often superimposed on a color display panel. A shutter panel is a panel that controls the passage of light. In the part where the light is not expected to pass through (such as the black part of the display screen), the shutter panel can block the light, and in the part where the light is expected to pass through (such as the color part of the display screen), the shutter panel allows the light to pass through, thereby allowing the light to pass through. Increases the light and dark contrast of the display device.

The arrangement order of the red sub-pixel SP1, the green sub-pixel SP2 and the blue sub-pixel SP3 can be adjusted according to actual requirements. In this embodiment, two adjacent first scan lines SL1 and two adjacent first data lines DL1 define a sub-pixel region SPr. In other words, two adjacent first scan lines SL1 and two adjacent first data lines DL1 define a sub-picture area of the element. In other words, the area surrounded by the pattern of the two adjacent first scan lines SL1 vertically projected on the substrate and the pattern of the two adjacent first data lines DL1 vertically projected on the substrate is defined as a sub-pixel area. The area of each first pixel PX1 is equal to the sum of the areas of the multiple sub-pixels.

In other embodiments, the active element T1 may also be a bottom gate type or other type of thin film transistor. In some embodiments In the figure, a light-shielding structure (not shown) is disposed under the active element T1, thereby preventing light (eg, light emitted by the backlight module) from irradiating the channel layer CH1, resulting in leakage problems.
