[0044] 为了示例清楚,结合附图分别描述ー下普通显示控制模式和画卷显示模式。 [0044] For clarity of illustration, in conjunction with the accompanying drawings described are ー normal display mode and a scroll display mode control. 參见图3B,假设为一幅原始图像,该原始图像由两个方格组成,分别为标注了“I”的方格和标注了“2”的方格,当辅屏完全从主屏上伸出时显示该完整原始图像(辅屏从左向右从主屏上伸出)。 3B, the image is assumed to be an original, the original image is composed of two squares, are marked "I" of the box and the box labeled "2", when fully extended from the auxiliary screen on the main screen displaying the original full image (left to right auxiliary screen protrudes from the main screen) of the. 假设辅屏仅从主屏上伸了一半,此时如果选择了普通显示控制模式,将仍然在该ー半辅屏上显示完整的图像,但是完整图像要在水平方向上压缩一半,參见图3C ;仍然假设辅屏仅从主屏上伸了一半,此时如果选择了画卷控制模式,则会在该一半辅屏上按照原图像比例显示一半的图像,參见图3D。 Suppose auxiliary screen on the main screen extends only half the normal time if the display control mode is selected, will remain in the complete image ー auxiliary screen displayed on half, but half of the complete image to be compressed in the horizontal direction, see FIG. 3C ; still assuming auxiliary screen on the main screen only stretch half time if the picture control mode is selected, the half of the display image, see FIG. 3D image according to the original ratio in the auxiliary screen half.

[0045] 步骤302 :当辅屏在使用状态下,位移传感器将探测到的辅屏的伸出长度值传输至显示控制模块。 [0045] Step 302: when the auxiliary screen in the usage state, the displacement sensor will detect the extended length of the auxiliary screen values ​​to the display control module.

[0046] 假设辅屏通过上下两个侧边上安装的滑轨可以在主屏上设置的滑槽内左右滑动,则为了探测辅屏在水平方向上的伸出长度,位移传感器可以安装在上侧边或下侧边的任意一个侧边上,该位移传感器可以具体为容栅传感器或者直线位移传感器。 Sliding around in the chute [0046] Suppose two auxiliary screen by the vertical sides of the mounting rail may be disposed in the main screen, the auxiliary screen in order to detect a length extending in the horizontal direction, the displacement sensor may be mounted on the side on any edge or side of a lower side of the displacement sensor may be embodied as a capacitive sensor or a linear displacement transducer. 位移传感器通常由动尺和定尺两部分组成,通过定尺和动尺的相对位移探测辅屏的伸出长度。 A displacement sensor movable scale usually consists of two parts and cut to length, and cut to length by moving relative displacement detection scale auxiliary screen projecting length.

[0047] 步骤303 :计算探測到的长度值与伸出方向上辅屏的长度值的比值。 [0047] Step 303: calculating the detected value of the length ratio of the length value and a direction extending auxiliary screen.

[0048] 參见图3E,为一种双屏笔记本电脑,该图仅用于描述辅屏相对于主屏的伸出长度,因此未示出所有部件。 [0048] Referring to 3E, the dual as a notebook computer, only the drawing for describing the auxiliary screen to the main screen of the projecting length, and therefore not all of the components shown. 其中,辅屏沿水平方向从主屏上伸出,辅屏从主屏上伸出一段距离,其中L为伸出方向上辅屏的长度值,即辅屏上下侧边的原始长度值,阴影部分为辅屏未伸出的部分,L'表示辅屏上下侧边从主屏上伸出的长度。 Wherein the auxiliary screen in the horizontal direction extending from the main screen, the auxiliary screen protrudes a distance from the main screen, where L is the length value of the projected direction of the auxiliary screen, i.e., the original length of the upper and lower sides of the auxiliary screen value, shaded auxiliary screen unextended portion, L 'denotes the length of the upper and lower sides of the auxiliary panel extending from the main screen.

[0049] 步骤304:判断当前显示控制模式的类型,若为普通显示控制模式,则执行步骤305 ;若为画卷显示控制模式,则执行步骤306。 [0049] Step 304: determining the type of the current control mode display, if the display control mode as normal, step 305 is performed; if the scroll display control mode, step 306 is executed.

[0050] 步骤305 :将主机输出的原始图像按照比值进行压缩,获得调整后的图像,执行步骤308。 [0050] Step 305: the original image is outputted in accordance with the host compression ratio, the image obtained after the adjustment, step 308 is executed.

[0051 ] 參见步骤301中结合图3C对普通显示控制模式的描述可知,假设比值为K,则K =じ/L0假设原始图像的分辨率为MXN,其中M为水平方向的分辨率,N为垂直方向的分辨率,则经过压缩后的图像的分辨率为(KXM) XN,由此实现普通显示控制模式。 [0051] Referring to step 301 in FIG. 3C described in conjunction with the normal display mode control understood assumed ratio is K, then K = ji / L0 is assumed that the original image resolution is Bank of Mexico MXN, where M is the horizontal resolution, N the resolution in the vertical direction, through the resolution of the image after compression is (KXM) XN, thereby enabling normal display control mode.

[0052] 步骤306 :生成參考图像,參考图像由全白图像和全黑图像组成。 [0052] Step 306: generating a reference image, the reference image is a completely white image and black image components.

[0053] 參见步骤301中结合图3D对画卷显示控制模式的描述可知,假设比值为K,则K =じ/L0假设原始图像的分辨率为MXN,其中M为水平方向的分辨率,N为垂直方向的分辨率,生成的參考图像中,其中全白图像的大小对应于辅屏上伸出部分的大小,即全白图像的分辨率为(KXM) XN,将全白图像中每个像素点设置为I (对应显示白色),而剩余全黑图像的分辨率为(IK) XMXN,将全黑图像中每个像素点设置为O (对应显示黒色)。 [0053] Referring to step 301 to scroll the display in conjunction with FIG. 3D description of the control mode is found, it is assumed for the ratio K, then K = ji / L0 is assumed that the original image resolution is Bank of Mexico MXN, where M is the resolution in the horizontal direction, N the resolution in the vertical direction, the reference image is generated, wherein the size of the all-white image corresponding to the size of the projecting portion on the secondary screen, i.e., the full resolution image is white (KXM) XN, each of the all white image pixel is set to I (corresponding to white display), and the remaining black image resolution (IK) XMXN, each image pixel is set to black O (black color corresponding to the display).

[0054] 步骤307 :将參考图像与原始图像进行逻辑与运算,获得调整后的图像。 [0054] Step 307: the reference image and the original image and the logical operation, the image obtained after the adjustment.

[0055] 将步骤306中由全白图像和全黑图像组成的參考图像与原始图像进行逻辑与操作,其中全白图像与原始图像逻辑与操作的结果仍然显示与全白图像大小一致的原始图像,而全黑图像与原始图像逻辑与操作的结果为仍然显示全黑图像,由此实现画卷显示控制模式。 [0055] The reference image in step 306 by the all-white image and a black image consisting of the original image is a logical AND operation, wherein the result of an all-white image and the original image is a logical AND operation of the still display the original image coincides with the full white size , the black image and the original image and the result of the logical operation is still display a completely black image, thereby realizing the display picture control mode.
