An electrochemical biosensor test strip with four new features. The test strip includes an indentation for tactile feel as to the location of the strips sample application port. The sample application port leads to a capillary test chamber, which includes a test reagent. The wet reagent includes from about 0.2% by weight to about 2% by weight polyethylene oxide from about 100 kilodaltons to about 900 kilodaltons mean molecular weight, which makes the dried reagent more hydrophilic and sturdier to strip processing steps, such as mechanical punching, and to mechanical manipulation by the test strip user. The roof of the capillary test chamber includes a transparent or translucent window which operates as a “fill to here” line, thereby identifying when enough test sample (a liquid sample, such as blood) has been added to the test chamber to accurately perform a test. The test strip may further include a notch located at the sample application port. The notch reduces a phenomenon called “dose hesitation”.

The invention discloses a device and a method for multi-region dynamically backlight driving. Light sources having different colors in each backlight sub-region of different sub-screen time regulating backlight modules and each colorful light switch unit (such as different liquid crystal pixels) are switched on or off in a sub-display sub-region corresponding to a display panel. For instance, when a red light source in a sub-backlight sub-region is switched on, the light source can pass by a red light switch unit on a corresponding sub-display sub-region while the red light switch units in other sub-display sub-regions in other adjacent sub-display sub-regions are switched off, thereby preventing the other adjacent sub-display sub-regions from being affected by the red light source. The method is applied to controlling other color light sources and light switches of the display in order to prevent the display of other adjacent sub-display sub-regions from being interfered by a backlight source corresponding to a specific sub-display region, so the light field disturbing effect between adjacent backlight sources is slight and no light separating unit is needed in the backlight sub-region.
