Weighing scale for use on a retail store counter, comprising a housing, a load-receiving platform that is arranged on top of the housing, and operating components that are enclosed in the housing, wherein the operating components include at least one weighing cell that is coupled to the load-receiving platform through a load-transmitting mechanical connection, analog and digital weighing electronics that are operable to convert electrical weight signals of the at least one weighing cell into digital weighing results, and a central processing unit which is operable to lend program-controlled functionality to the weighing scale, and further comprising a touchscreen display panel (7, 21, 22, 23) which is operable to display information to, and receive input from, a human operator, wherein the touchscreen display panel (7, 21, 22, 23) comprises a layered arrangement in which a protective glass plate, a projected capacitive (PCAP) touch screen with a plurality of touch-sensing points, and a liquid crystal display are arranged on top of each other, characterized in that at least a part of the touchscreen display panel (7, 21, 22, 23) is integrated in the load-receiving platform in horizontal orientation, with a top surface of the protective glass plate exposed and facing the human operator, and further that constructive features are present to prevent the occurrence of weighing errors due to electrical connections causing mechanical bypass forces between said at least one part of the touchscreen display panel (7, 21, 22, 23) that is integrated in the load-receiving platform and the operating components that are installed in the housing while the PCAP touch screen and the liquid crystal display are installed in the housing, separated by a small air gap from the glass plate, wherein said constructive features comprises a flexible conductor between the load-receiving platform and the operating components that are installed in the housing and said flexible conductor is configured as a spring element with an elastic restoring force that superimposes itself on the weighing force in a predictable and reproducible manner so that the influence of the flexible conductor will be cancelled in a calibration of the weighing scale; or said constructive features comprise an arrangement without an electrical connection between the load-receiving platform and the operating components that are installed in the housing, wherein the arrangement comprises wireless sending and receiving means for a wireless transmission of power and data between the load-receiving platform and the operating components that are installed in the housing, wherein the top surface of the protective glass plate is operable to perform three functions, namely a first function as load-receiving surface of the weighing scale on which merchandise to be weighed can be placed by the human operator, a second function as touch field keyboard (40, 41, 42, 47) through which inputs are communicated to the weighing scale by the human operator, and a third function as display window (43, 46, 48) through which information is delivered by the weighing scale to the human operator, and that, consequently, said layered assembly (21, 22, 23) forms a combined load plate/touchscreen/display panel (3, 22, 23).
